At-home micronutrient testing kits allow individuals to easily check their blood levels of certain vitamins and minerals without leaving home. You collect your sample, mail it in, and receive your results electronically. In some cases, micronutrient testing at home may also be less expensive than having lab work done at a medical facility.

The best at-home micronutrient testing offers simple sample-collection methods and utilizes labs that follow strict quality control and materials-handling guidelines to ensure the accuracy of results. Some may offer tests for several micronutrients from one blood sample, while others may check a single biomarker.

LetsGetChecked’s laboratory is CLIA certified and CAP approved, so you can trust your test results to be accurate as long as the finger-prick blood sample was taken correctly.

LetsGetChecked has overall positive reviews, but some reviewers would like more health recommendations from the company after receiving their results. Note that due to legal restrictions, the test is not available in New York.

Best for Accuracy : Rootine Blood Vitamin Test



Key Specs
  • Pricing: Approximately $105
  • Availability: Not available in New York
  • Results: Available in about three days after your kit arrives at the lab
Why We Chose It

Rootine’s Blood Vitamin Tests are conducted in a CLIA-certified lab.

Pros & Cons
  • CLIA certified lab

  • Pairs blood and DNA testing for customized supplements

  • Tests for 5 analytes

  • Subscription is expensive

  • Vague sample-collection instructions on website


This blood test from Rootine checks your vitamin B9, vitamin B12, hsCRP, and homocysteine levels. It’s an optional part of their vitamin subscription service, and your results can be used to customize the vitamin formulation you receive.

The Blood Vitamin Test can be ordered online for roughly $105. You can also opt in to their monthly vitamin subscription for about $69 per month.

Rootine also offers an optional DNA test for about $105. Shipping is free, but Rootine is not eligible for FSA or HSA funds, and the test cannot be shipped to New York.

Rootine shines in its quality control processes. Not only are its labs CLIA approved, but it also conducts extensive in-house and third-party testing on its supplements through NSF, Institut Kurz, and GE.

The test kit requires a simple finger prick. However, the full instructions for the test are not provided online—at least, not outside of the member area. Results will be ready approximately 3 days after your blood sample is received.

Although the subscription is expensive, many reviewers say that it’s worth it, and they feel much more confident in Rootine vitamins than other brands because they are specially formulated based on their DNA and blood testing results.

Rootine also pairs your test results with your DNA information to make customized vitamins in microbead formulations, which are easier to swallow and may offer time-release benefits superior to pills.

Best on a Budget : Thorne Vitamin D Test



Key Specs
  • Pricing: Approximately $99
  • Availability: Not available in Maryland, Hawaii, North Dakota, South Dakota, New York, New Jersey, or Rhode Island
  • Results: In eight to 10 business days
Why We Chose It

If you’re on a budget, single nutrient tests are more cost efficient than a more complete panel. The Vitamin D Test from Thorne is less than $100 and offers insights into your vitamin D status, which for most people in the United States is less than optimal.

Pros & Cons
  • Less than $100

  • Can be paired with Thorne supplements

  • CLIA or CAP certified

  • Only one biomarker tested

  • Unavailable in seven states

  • Thorne supplements can be expensive


If you can only afford one test, this one from Thorne—a reputable supplement company—is a good choice. According to the National Institutes of Health, most people don’t get enough vitamin D for optimal health.

Most home tests that assess your blood levels of multiple biomarkers cost well over $100, so it’s more cost efficient to choose one marker to test. This Vitamin D Test from Thorne costs about $99; shipping is free, and your test should arrive within three to four days after ordering.

Thorne does accept HSA and FSA funds for its tests, although you may need to request reimbursement after purchase rather than using the funds up front. You can also subscribe to save 20% on future retests.

To test, you’ll need to first activate your kit on the Thorne website. Then, take a finger-prick blood sample and mail it in. Your results will be ready within 10 business days. If your vitamin D levels are low, you’ll be given an option to purchase or subscribe to Thorne vitamin D supplements, which can be expensive compared to other brands.

While Thorne has a mobile app for iOS, it appears to be mostly for shopping and not designed to support test results or other functions. 

Thorne contracts with labs that are either CLIA or CAP certified to help ensure quality and consistency in its processes. There are few reviews available for its tests, but most are favorable and say that the tests provided some valuable insights. 

Note that unlike other testing companies, Thorne excludes seven states from its tests due to legal restrictions: Maryland, Hawaii, North Dakota, South Dakota, New York, New Jersey, and Rhode Island.

Best for B Vitamins : Everlywell B Vitamins Test

EverlyWell Indoor & Outdoor Allergy Test

EverlyWell Indoor & Outdoor Allergy Test

Key Specs
  • Pricing: Approximately $89
  • Availability: Not available in New York
  • Results: Available in five to seven business days
Why We Chose It

Everlywell is a well-known and reputable health testing company, and one of the only companies offering an at-home test just for B vitamins.

Pros & Cons
  • Tests levels of three B vitamins

  • Inexpensive compared to other tests

  • CLIA approved

  • May sell out

  • Not a comprehensive B vitamin panel

  • Slow results according to some reviews

  • B vitamin deficiencies are very rare so tests may not be needed


Everlywell is a health testing company offering a variety of home hormone and nutrition tests. Its lab is CLIA approved, which helps to ensure accuracy. The B Vitamins Test costs roughly $89 with free shipping when you order online. However, Everlywell also offers a membership program called Control, which allows you to take one health test per month for around $25. The company also accepts FSA or HSA funds for payment.

The B Vitamins Test from Everlywell tests specifically for vitamin B12, vitamin B6, and vitamin B9 (folate). Your blood levels of these specific B vitamins can be influenced by your diet, although there are several other B vitamins that aren’t included in this test.

The sample needed is a finger-prick blood test. Simply activate your kit, collect your sample, mail it in, and wait for results, which should be available within seven business days. You’ll be able to view them on the Everlywell website.

Overall, Everlywell and this test in particular have positive reviews. However, many reviewers have complained of long waits to get test results and difficulty getting a complete blood sample using the lancets included in their kit. Note that Everlywell doesn’t offer tests in New York due to legal restrictions.

It should be noted, however, that B vitamin deficiencies are very rare in the US because they are usually fortified in everyday foods — so this test may not be needed for most Americans.

Gastric surgery, pregnancy, and certain neurological complications can all sometimes require people to take B vitamin supplements — but in those cases, your doctor will probably already be monitoring you closely.

Final Verdict

There are only a handful of companies offering at-home micronutrient testing, despite the fact that this is a popular service. Rootine offers micronutrient tests as part of their supplement subscription model. Thorne also offers limited micronutrient testing, like their Vitamin D test.

LetsGetChecked offers a comprehensive micronutrient test that checks your levels of seven different vitamins and minerals, and you may have your results back in as little as two days. LetsGetChecked also utilizes CLIA- and CAP-certified laboratories and provides clear and thorough testing instructions for their customers.

Guide for Choosing the Best At-Home Micronutrient Testing

Is At-Home Micronutrient Testing Worth It? 

Micronutrient testing may be something for you to consider if you’re:

  • Showing signs of a vitamin deficiency: Unexplained fatigue, brain fog, or changes to your hair, skin, and nail quality may be signs of a vitamin deficiency. A home micronutrient test can help shed light on what could be causing these issues, but you should always follow up with a healthcare provider if you are experiencing symptoms such as these.
  • Concerned about your diet: If you are worried that your diet may not be providing all of the nutrients you need, a home micronutrient test can help provide some answers and show you some areas in which your diet may need to be tweaked to support optimal health.
  • In a group that may be at higher risk of vitamin deficiency: Certain groups of people may be at higher risk of experiencing nutrient deficiencies. For example, vegans are generally at a higher risk of vitamin B12 deficiency. Vitamin B12 comes primarily from animal foods and requires supplementation in the vegan diet. People with darker skin may be at increased risk of vitamin D deficiency because they synthesize less vitamin D during sun exposure than people with lighter skin. Pregnant women may be interested in knowing their folate (vitamin B9) levels because a deficiency can increase the risk of spinal cord defects in their baby.

Alternatively, if you’d like a more comprehensive look at your health and micronutrient status, you may need to have lab work ordered through your healthcare provider. For instance, none of these home testing kits check your iron level, but pregnant and premenopausal women may struggle to get enough iron in their diet.

Comparing At-Home Micronutrient Testing

When deciding which micronutrient test is the best fit for you, here are some things to consider:

  • Cost: Most of these kits cost $100 or more, but it’s less expensive to test for a single biomarker than for multiple. If you go through your healthcare provider, you may be able to get lab tests through an in-person lab for a lower out-of-pocket cost depending on your insurance.
  • Turnaround time: If you are anxious for your results, go with one of the quicker testing services like LetsGetChecked. However, if you don’t mind waiting a bit longer, then you have a few more options.
  • Sampling method: All of these tests employ a finger-prick blood test except.
  • Accuracy: While none of these services made any claims about the accuracy, they all have certifications from or compliance with bodies regulating quality control in laboratory testing or supplement development, like CLIA, COLA, CAP, and ICH.
  • Nutrients tested: One of the biggest considerations is which nutrients you want to have checked. For instance, if you’re concerned with immune health, you’ll want a test that includes vitamin D; if you’re pregnant, you’ll want to check your folate status.

Ordering Your At-Home Micronutrient Testing Kit

Most at-home testing kits have to be ordered directly from the manufacturer as they are not usually available via third-party sellers like Amazon or Walmart.

When you receive the kit, do a quick inventory to make sure all of the necessary materials are there, and then thoroughly read the instructions before you collect your sample. Some tests require a fasting period, while others need to be done on certain days of the week for shipping purposes. Some need to be done as soon as you wake up, and others may be done any time of day. Most of them need to be placed in the mail to be sent back to the lab on the same day the sample is taken.

In most cases, you’ll also need to activate your test online before sending off your sample. This lets the testing company know to expect your sample and allows them to keep you updated on where your sample is in the process.

When you receive your results, your report will probably include some additional information about how to interpret your results and further recommendations for supplements or lifestyle changes you can implement. If you have any concerns about your results, make an appointment to speak with your healthcare provider.

Frequently Asked Questions
  • How much does at-home micronutrient testing cost?

    At-home micronutrient tests range from about $65 to nearly $200. The price mostly depends on the number of micronutrients being tested. Single-nutrient tests tend to be less expensive, while more comprehensive panels will command a higher price.

  • Is at-home micronutrient testing accurate?

    At-home blood tests can be accurate, but it depends on a number of factors—like if you were fasting when you tested, if you were taking supplements during your sample period that may have affected your results, how the blood was collected and managed throughout the shipping and testing process, and more.

    Certifications like CLIA, COLA, or CAP help to ensure that quality control procedures are in place to maximize test accuracy. However, if you have any concerns about the results of your home testing kit, you should speak to your healthcare provider.

  • Can at-home micronutrient testing find vitamin deficiencies?

    While at-home micronutrient testing can show you if your blood levels of a certain nutrient are low, these services stop short at diagnosing nutrient deficiencies or other conditions. That is a conversation you’ll need to have with your healthcare provider.

  • Who should use at-home micronutrient testing?

    Anyone can use a home micronutrient test, although it may be better for people who are concerned about the quality of their diet and if it’s providing enough vitamins—for instance, people following a vegan diet or a calorie-restricted diet for weight loss.

    Additionally, you may want to try a test if you’re experiencing unexplained mild symptoms like brain fog or fatigue. A nutrient test may help point you in the right direction. However, you should meet with your healthcare provider to discuss any concerns you may have.


We evaluated nearly 20 different lab testing services to find the best at-home micronutrient testing providers. First, we filtered out the services that did not provide home testing kits. Next, we narrowed down the list to services that specifically offer micronutrient tests. 

Finally, we chose micronutrient testing kits that use a quality standard like CLIA certification or CAP accreditation and blood testing, to help ensure that the test results are as accurate as possible. Tests employing the use of saliva or hair didn’t make the cut, as these don’t provide a snapshot of your current nutrient status.
