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 uses 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. These are the at-home micronutrient tests we recommend.

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

To complete the test and get your results, you’ll first need to activate the test on the LetsGetChecked app or website. Then, collect your sample and mail it off. You’ll be notified when your results are ready. If you have the LetsGetChecked app, you can use it to both order tests and check your results.

Key Specs
  • Pricing: Approximately $115
  • Availability: Not available in New York
  • Wait Time for Results: About three days after kit arrives at 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, vitamin D, hsCRP, and homocysteine levels. It’s an optional part of the company's vitamin subscription service, and you can use your results to customize the vitamin formulation you receive.

Order the Blood Vitamin Test online for roughly $115. You can also opt into quarterly testing for $95 and a monthly vitamin subscription for about $69 per month.

Rootine also offers an optional DNA test that also runs about $115. 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. Its labs CLIA approved, plus it also conducts extensive in-house and third-party testing on its supplements through NSF International, Institut Kurz, and GE Labs.

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 three 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 customers' DNA and blood testing results.

Best on a Budget : Thorne Vitamin D Test



Key Specs
  • Pricing: Approximately $99
  • Availability: Not available in Maryland, New Jersey, New York, or Rhode Island
  • Wait Time for Results: Eight to 10 business days
Why We Chose It

If you’re on a budget, single nutrient tests are more cost-effective than a more complete panel. The Vitamin D Test from Thorne is under $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 four 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 blood levels of multiple biomarkers cost well over $100, so it’s more cost-effective to choose one marker to test. This Vitamin D Test from Thorne costs about $99; shipping is free, and your test should arrive within five bussiness 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 four states from its tests due to legal restrictions: Maryland, New York, New Jersey, and Rhode Island.

Final Verdict

There are only a handful of companies offering at-home micronutrient testing. Rootine offers micronutrient tests as part of its supplement subscription model. Thorne also offers limited micronutrient testing, like a vitamin D test.

Our top pick, 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 uses CLIA- and CAP-certified laboratories and provides clear and thorough testing instructions for customers.

Guide to Choosing the Best At-Home Micronutrient Testing

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.

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: Vegans who avoid food from animal sources are generally at a higher risk of vitamin B12 deficiency and may need supplements. People with darker skin synthesize less vitamin D during sun exposure than people with lighter skin. Pregnant people may want to know their folate (vitamin B9) levels due to the fetal risk for spinal cord defects.

Comparing At-Home Micronutrient Testing

When deciding which micronutrient test is the best fit for you, here are some factors 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 ones. 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: These tests usually rely on a finger-prick blood sample.
  • Accuracy: While none of these services made any claims about 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. 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 testing 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

  • Is At-Home Micronutrient Testing Accurate?

    Accuracy of at-home blood tests depends on factors like whether you fast or take supplements when the blood sample was taken, and how it was handled during collection, shipping, and at the lab. Certifications like CLIA, COLA, or CAP help to ensure that quality control procedures will maximize test accuracy.

  • Can At-Home Micronutrient Testing Find Vitamin Deficiencies?

    At-home micronutrient testing can show you if blood levels of a certain nutrient are low, but these services stop short of diagnosing nutrient deficiencies or other conditions. You’ll need to discuss results with your healthcare provider to get a diagnosis.

  • Is At-Home Micronutrient Testing Worth It?

    At-home micronutrient testing may be helpful to test for a specific deficiency like vitamin D. You may need to have lab work ordered through your healthcare provider, though. For example, none of these home testing kits check your iron level, but that remains a key concern for pregnant people.

  • How Do You Fix Micronutrient Deficiency?

    The remedy for many vitamin and mineral deficiencies is often found in changing or improving your diet, or by adding supplements. Sometimes, an underlying health condition may need to be treated. Be sure to discuss your results with your healthcare provider.


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.
