What We Look For in the Best At-Home Thyroid Tests
To make sure you get the best value for money and accurate results, we examined each test against very specific factors.
- Relevant results: A thyroid test should screen for all the biomarkers that influence the function of your thyroid, especially TSH, FT4, and FT3.
- Detailed reports: Your report should be easy to understand and give you all the information you need.
- Accurate results: It’s important that you get results you can rely on and that you know are accurate.
- Quick turnaround: No one wants to be waiting for weeks to discover a potential health problem.
- Budget-friendly: Your thyroid test shouldn’t break the bank, either. It should offer good value for money with everything you need.
1. LetsGetChecked – Best Overall For Accurate, High-Value Thyroid Testing
- Choose from two thyroid tests – thyroid hormones or thyroid antibodies
- Screens for TSH, FT3, FT4, TGAB, and TPO/TPEX
- Subscription options available for ongoing, cheaper testing
- Free follow-up phone call with a nurse for any positive results
- Results in 2-5 days
LetsGetChecked is our top pick for at-home thyroid tests. It’s quick, discreet, and incredibly accurate. You can choose from two different thyroid tests – a thyroid hormone test and a thyroid antibody test.
The thyroid hormone test identifies the presence of key thyroid hormones, including thyroid-stimulating hormone (TSH), free triiodothyronine (FT3), and free thyroxine (FT4). It’s ideal if you’re starting to show signs of hyperthyroidism or hypothyroidism.
The second, more in-depth test screens for the three most important hormones, but it also checks for antibodies that can cause thyroid disorders and autoimmune diseases. It analyzes thyroglobulin antibodies (TGAB) and thyroid peroxidase antibodies (TPO/TPEX) to give you the complete picture of your thyroid function. And it’s one of the few tests that screens for TGAB.
With either test, you get a detailed online report that’s easily digestible. It tells you the exact levels of each hormone or antibody in your body, so you can see how you compare to normal levels.
Taking the test is really easy, too. All it requires is a simple finger-prick blood sample, so you’re done in less than five minutes. It’s free to return to the lab.
All of LetsGetChecked’s labs are CLIA- and CAP-certified, and your results are reviewed by qualified physicians. Best of all, you can get your results in 2-5 days.
Should you test positive, you can speak with a nurse to discuss your results. And it’s free!
Although LetsGetChecked doesn’t accept insurance, you can pay with FSA and HSA cards. You can even sign up for thyroid test subscriptions, so they’re delivered to your door every 3 months. That’s great for keeping on top of your thyroid management, and it saves you 30% in price.

2. Everlywell – Best For Personalized Advice on Thyroid Management
- Screens for TSH, FT3, FT4, and TPO/TPEX
- Personalized advice for all biomarkers with next steps
- Quick, finger-prick blood test
- Results in a couple of days
Everlywell has an all-in-one thyroid test that screens for TSH, FT3, FT4, and the thyroid disorder antibody TPO/TPEX, so you can understand whether you may have a thyroid dysfunction.
The test requires a finger-prick test with a blood sample. It’s quick and relatively painless, so don’t worry.
Your results include a personalized report of each biomarker tested, with your exact levels and whether they’re low, normal, or high. You also get actionable advice on what each biomarker means for your health and what you should do next. These are specific to your body’s needs, rather than generalized tips.
As well as personalized advice, you get access to recommended resources to learn more about your results and how to manage your thyroid.
Although you don’t get a follow-up phone call with a healthcare professional, your results are designed specifically so that you can take them to your doctor. From your secure online platform, you can download your results, send them to your physician, and get treatment sorted right away.
Usually, it only takes a couple of days to get your results. You get an email to tell you when they’re ready, and you just need to log in to the online dashboard.
You can rely on Everylwell for accuracy, too, since your results are reviewed in certified labs by qualified physicians.
There are semi-annual subscription options available for ongoing testing. It gives you a 15% cost saving overall.

3. Paloma Health – Best For Diagnosing & Tracking Thyroid Changes
- Tests for FT3, FT4, TSH, and TPO
- Can diagnose hypothyroidism
- Ongoing testing options to monitor changes, plus nutrition and medical advice
- Personalized tips and advice based on your thyroid’s needs
Paloma Health’s at-home thyroid test is easy to use, quick, and comes with ongoing testing for you to track your thyroid performance over time. It’s the only test to actually diagnose hypothyroidism. Most tests give you information that could indicate a problem, but don’t actually diagnose a condition.
Your kit is sent directly to your home, free of charge. It usually arrives within 3 days and it takes around 7 days to get your results. So the whole process is very quick.
It screens for your levels of FT3, FT4, TSH, and TPO in your blood with a simple finger-prick blood test. You can see your exact levels of each biomarker in your results, which quickly shows you whether you have normal thyroid function or if you’re in the danger zone.
You get a customized plan that advises you on your next steps, based on what your body needs. And for those with thyroid issues, Paloma Health automatically sets up ongoing testing so you can monitor changes over time.
You can even get personalized advice on managing your thyroid for free. There’s an online quiz that asks a series of questions about your history, current health, and goals. It gives you some basic tips to get started.
If you require further support, you can set up a consultation with a doctor or nutritionist. You receive dietary advice, learn about your triggers, and can identify any deficiencies. And the doctors can provide you with all the treatment and medical advice you need. There is a charge for both of these services.
Paloma Health also offers subscriptions for thyroid supplements that are delivered to your home monthly. Again, there’s a charge, but it means you can get everything in one place.

4. SelfDecode – Best For a Lifetime of Thyroid & Wellness Tests
- Annual and lifetime subscriptions with access to 20+ reports
- Screens 23 genes related to thyroid function
- Examines your predisposition for autoimmune thyroid conditions
- Results in 1 month
SelfDecode is quite unique. It offers an annual or lifetime subscription option which gives you access to individual wellness reports, including one for thyroid. There are also reports for sleep quality, vitamin response, cardiovascular health, and much more.
Yearly access gives you five reports every year, plus 50% off any other reports of your choice. You can mix and match as you please – there are over 20 to choose from.
First, you need to take the DNA test to determine your genetic profile, then you can upload your file to get your thyroid report.
The thyroid report analyzes 23 of your genes related to thyroid function, which includes the most common biomarkers: TSH, FT3, and FT4. It also assesses your predisposition for autoimmune thyroid conditions and whether you have any iodine deficiencies.
Your report is very comprehensive and includes both lifestyle and gene-based advice to guide you. It gives you actionable advice on how your nutrition, sleep habits, and stress can impact your thyroid and, importantly, what to do about it.
SelfDecode also recommends thyroid supplements so you know what you should be taking to improve your health.
Plus, you have access to a personalized genetics blog. Every week, you get blog articles personalized to you and your genes. You can find plenty of suggestions based on thyroid biomarkers and how to adapt your lifestyle.
Even if your thyroid biomarker levels come back as normal, you can still track your results to learn how to improve your thyroid function. The Lab Test Analyzer Tool allows you to upload your DNA results and gives you tips to steer you towards optimal health.
Results take one month. But once you’ve tested your genes once, you don’t need to do it again. You can keep uploading your existing DNA file to get new reports in other wellness areas in just a few minutes.

5. EasyDNA – Best For Graves’ Disease Screening
- Assesses your predisposition for Graves’ Disease, caused by an overactive thyroid
- Determines your risk for 33 other genetic diseases
- Easy, quick cheek swabs
- Results within 3 weeks
EasyDNA offers a genetic predisposition test for Graves’ Disease, which might indicate that you have an overactive thyroid. It’s only available in New Zealand and the UK, though.
There’s no blood sample involved, just four simple cheek swabs. It screens your DNA to examine your predisposition to Graves’ Disease, rather than actually testing your levels of Thyroid hormones. So it won’t give you information about your FT3 or FT4 levels, but it will tell you what your risk is compared to average risk.
The genetic predisposition test doesn’t only screen for thyroid dysfunction. You can learn about your lifetime risk for 34 major health conditions, including common auto-immune diseases, eye problems, cardiovascular health conditions, and more. So it’s a good choice for bundling your test and learning more about your health.
Your results usually take 3 weeks.
Your report isn’t the most detailed I’ve seen, but it gives you the basic info you need to know. It tells you your current risk level, and whether it’s high, medium, or low for all the 34 health conditions. There’s no extra support involved, but you can easily print your results to take them to your doctor.
6. Health Testing Centers – Best For Choice of Thyroid Tests
- Huge choice of individual thyroid tests, plus two bundle kits
- Screens for TSI, T3 uptake, FT4, FT3, and more
- Same-day testing available
- Results in 1-2 days
Health Testing Centers has the biggest line up of thyroid tests I’ve seen. You can choose from thyroid tests that screen for individual thyroid hormones, including TSH, FT4, and FT3. There’s even a test for TSI.
If you don’t fancy an individual test, there are also two bundle kits – the expanded panel test and the comprehensive thyroid test. Both of these screen for other thyroid indicators that you might not find anywhere else. That includes a test for T3 uptake, which measures the number of proteins in your blood capable of carrying a thyroid hormone.
With Health Testing Centers, you don’t actually take your test at home. You need to visit one of their labs to take the test instead, so it might not as private as you were expecting. But you still remain anonymous in the lab and don’t have to fill out any extra forms. They’re all CLIA-certified, too.
You can actually buy and take your test on the same day, so it works well for anyone in need of urgent testing. And your results are usually ready in 1-2 days.
You’re notified by email as soon as your results are available from your online platform. They usually look like a medical report, with a simple positive or negative result, so they’re easy to understand. If your results show up anything concerning, a nurse calls you to give you advice on what to do next.

7. TellmeGEN – Best For an All-In-One Thryoid & Overall Health Test
- Comprehensive health test including screening for 100+ health conditions
- Assesses your thyroid function and likelihood of developing hyperthyroidism or hypothyroidism
- Nutrition and medical consultation services available
- Results in 4-6 weeks
TellmeGEN has a comprehensive health test that examines your thyroid function, alongside many other things. It screens for over 45 different personal traits, which include your TRH, TSH, FT3, and FT4 levels to determine the effectiveness of your thyroid.
As well as learning about your likelihood of hyperthyroidism or hypothyroidism, you can learn about your memory, sleep habits, eye color, skin pigmentation, and much more.
It doesn’t end with personal traits, either. The comprehensive TellmeGEN test includes screening for over 100 genetic predisposition to diseases, pharmacological compatibility, whether you’re a carrier of hereditary monogenic diseases, and your overall wellness, including diet information. It even gives you ancestry information.
Testing only requires a saliva sample, with free returns to the testing lab. From arriving at the lab, it usually takes 4-6 weeks to gather your results.
You can access your report online from the dashboard and download it as a PDF if you like. It’s very detailed because of all the different health and wellness aspects the test covers. The actual thyroid section is only small, so you don’t get too much insight into the function of your thyroid. You do get a great overview of your overall health, though.
You can also buy nutritional or medical counseling services for an extra fee, to talk you through your results and give you tips on altering your lifestyle.
What’s In the Fine Print?
Before you buy your chosen test, it’s always worth checking out the fine print to see if you’ll incur any extra costs along the way. It could be added fees for shipping, processing, medical consultations, or even for recommended supplements. And I’ve examined all the terms and conditions for you.
You get free shipping with all the tests on this list. That includes return shipping, too, so you don’t need to pay anything extra to send it back to the lab for processing. With Health Testing Centers, there are no shipping costs anyway because you take your test in the lab, but that’s completely free, too.
No test charges you extra for processing your kit or producing your results, but you usually have to pay a fee for some of the extra services on offer, such as medical or nutritional consultation.
Both Paloma Health and TellmeGEN offer consultancy services, and you are charged for them. The fee usually ranges between $49-$99 for a 30-60 minute consultation and report.
You don’t have to pay everywhere, though. LetsGetChecked offers a free follow-up phone call with a nurse for any positive results. They can talk you through your thyroid management and give you medical advice on what to do next.
You can also buy supplements from Paloma Health designed to help you manage your thyroid, but again, these come at a cost of around $30 a month. If you subscribe to monthly deliveries, you can save 10%, though.
EasyDNA’s genetic predisposition test is only available in the UK or New Zealand, so bear that in mind before choosing your kit.
How Do Our Top Picks Compete on Price?
LetsGetChecked offers the best value for money by far. Although it’s priced the same as Everlywell and Paloma Health, you get much more included with your fee. All three of these tests cost you less than $100.
LetsGetChecked throws in a free follow-up phone call with a nurse, and it has the most comprehensive thyroid testing kit, too. It screens for TGAB, which you don’t see often.
With LetsGetChecked and Everlywell, you can save more money with the subscription options. LetsGetChecked offers the biggest discount of 30% saving with a kit delivered to your door every 3 months. Everlywell cuts the cost of your kit by 15%with a semi-annual subscription, which is also a great deal.
Paloma Health is priced the same as my first two recommendations, so it’s very budget-friendly and you get a lot for that fee. You have to pay extra for consultancy and supplement deliveries, though, so costs can soon add up.
Health Testing Centers offers the cheapest kit on this list, starting at less than $50. That’s for an individual kit, though, so it only screens for one thing. Their bundles are quite a bit more expensive, costing over $130. But you do get screening for TGAB and other factors like T3 uptake.
TellmeGEN’s kit only costs a fraction more than Health Testing Centers’ complete thyroid test, and you get everything there is to know about your health, plus full ancestry information. For an all-in-one kit, TellmeGEN is very well priced.
The most expensive option is Easy DNA, coming in at around $450. It does offer full genetic predisposition screening, though, so as well as your risk of thyroid problems, you can learn about your cancer risk, heart health, and much more.
Which Is the Best Thyroid DNA Test?
I’d recommend any of the seven tests on this list. But if you want the best value for money, go for my top pick LetsGetChecked. Not only is it budget-friendly, but it screens for everything you need to know, and you get a free phone call with a nurse.
LetsGetChecked and Everlywell offer subscription options, which is ideal if you’re in need of ongoing thyroid testing. You can get kits delivered to your door either every three months or twice a year. Plus, it means you save money.
There’s another subscription option on offer from SelfDecode, with yearly access costing you just less than $100. You do have to pay an extra $90 for the initial DNA test, but once you’ve had one test you can keep uploading your DNA file which helps you save money.
Paloma Health might be right for you if you’re looking for the full works. It charges for medical and nutritional consultations, plus on-going supplements, but it means you can get everything from one place, and for a good price, too.
Only interested in one aspect of your thyroid? Go for Health Testing Centers. It has a huge list of individual tests which means you can pick only the one you need. Or, you can choose one of their two bundles. I’d also recommend Health Testing Centers if you want to screen for FT3 uptake or reverse FT3, as you won’t get that anywhere else.
If you want to learn about other aspects of your health at the same time, try EasyDNA or TellmeGEN. EasyDNA tells you your predisposition for tons of different diseases in a detailed report. And tellmeGEN screens for over 100+ different health conditions, examines your ancestry, and looks at your personal traits.

FAQs
Are thyroid tests accurate?
That depends on which test you choose. If you go with any of the recommendations on this list, your results are physician-reviewed and examined in CLIA-certified labs. My top choice LetsGetChecked even manufactures all of its kits with the ISO 13485 accreditation, which is the highest possible medical accreditation around. That means at least 99.9% accuracy of your results.
If you chose an unreputable company, though, you can’t be sure of the reliability of your results, so it’s always best to go with trusted providers. And remember, no test can ever offer 100% accuracy, so there’s always a (very) small room for error, even with the best tests.
What do thyroid test numbers and levels mean?
Thyroid test results can be confusing, but they usually include three main readings – thyroid stimulating hormone (TSH), free triiodothyronine (FT3), and free thyroxine (FT4).
The TSH shows the strength of the signal your brain is sending to produce more thyroid hormone. The normal range for TSH is 0.27 – 4.2 mlU/L, but medical professionals recommend values of <2.0 mlU/L if you’re taking synthetic thyroid hormone medications.
A high TSH value means your brain is sending a strong signal to your thyroid gland, and you’re not producing enough thyroid hormones (FT3 and FT4). A low value means your brain is sending a weak signal to your thyroid gland, and you’re producing too much FT3 or FT4.
FT3 is a thyroid hormone that’s released into your bloodstream to help control your metabolism. The standard range for FT3 levels is between 1.1-3.0 nmol/L.
FT4 is also a thyroid hormone in your bloodstream. A high level of FT4 might confirm the diagnosis of hyperthyroidism, known as an overactive thyroid. Likewise, low levels can indicate hypothyroidism, which means your thyroid is underactive. Usually the standard range is <60-145 mmol/L.
What can a thyroid test detect?
A thyroid test can detect a variety of endocrine conditions. Overall, a thyroid test looks to detect whether your body has enough thyroid hormone, and if the signal from your brain to produce the thyroid hormone is the right strength.
Having thyroid levels that are too high or low could indicate hyperthyroidism or hypothyroidism, which can affect factors like weight gain and loss, sleep quality, anxiety, heart rate, and more. Most thyroid tests can’t diagnose either of these conditions, but they can indicate problems. You will need to take your results to a medical professional to get an accurate diagnosis.
Who should get a thyroid test?
You might want to consider taking a thyroid test if you’re experiencing symptoms related to thyroid dysfunction. This includes difficulty sleeping, rapid weight gain or loss, depression and anxiety, low or high heart rate, and heat intolerance.
If you have a history of thyroid cancer in your family, or your family members have a thyroid condition, it may also be a good idea for you to take a test to determine the likelihood of developing a thyroid-related health condition.
How often should thyroid tests be done?
It’s a good idea to take thyroid tests regularly to determine whether there have been any changes to your thyroid function over time and even if your medication is performing correctly. How often you take the tests, though, is a completely personal decision. And it’s also one you should make in consultation with your doctor.
Certain tests like LetsGetChecked offer subscription options, so you can get a thyroid test delivered to your door every three months. This allows you to keep on top of your thyroid management, and it can help you save money, too, as tests are much cheaper if you sign up for a subscription.
Which thyroid home test should I get?
There are many different at-home thyroid tests available, and I’ve found the top seven for you based on weeks of research and in-depth testing. The best test for you depends on a number of factors, including which thyroid hormones you’re looking to test, the level of detail you need from your report, and obviously, your budget.
I’d recommend LetsGetChecked as the #1 thyroid test because it screens for all the necessary thyroid hormones to give you a highly detailed report with actionable tips. You also get a free call with a nurse to discuss your results, which most other services charge for. And there are subscription options available, too.
