Best At-Home Micronutrient Testing

LetsGetChecked offers a variety of at-home health tests, and its Home Micronutrient Test is one of the most thorough nutrient tests available. It assesses blood levels of vitamin D, vitamin B12, vitamin E, copper, selenium, zinc, and magnesium. The Home Micronutrient Test from LetsGetChecked earns our top spot because it’s comprehensive, fast, and processed by a trustworthy lab.

The test is roughly $179, and you can use flexible spending account (FSA) or health savings account (HSA) funds to pay for it. Shipping is free, and the test should arrive within seven days.

The sample-collection process is fairly straightforward, but there are several steps involved so it’s important to closely follow the directions. There is a helpful explainer video on the LetsGetChecked website if you need extra guidance to prepare your sample.

The labs LetsGetChecked uses are Clinical Laboratory Improvement Amendments (CLIA)-certified; this is a quality assessment program administered by the Centers for Medicare and Medicaid Services. They are also accredited by the College of American Pathologists (CAP).

You can expect to receive your results in two to five days. You can view them online, or on the LetsGetChecked mobile app (available in the Apple App Store and Google Play).

Overall, reviewers are pleased with LetsGetChecked tests and the testing experience they provide. However, some express that they’d like more information and health recommendations after receiving their results. Note that the test is not available in New York due to legal restrictions.

The Essential Vitamin Test from LetsGetChecked assesses your blood levels for three key vitamins that may be low for certain people (like vegans): vitamin B12, vitamin D, and vitamin E.

You can order the test for about $109 (with free shipping), and use FSA or HSA funds to pay for it. It should arrive at your home about five to seven days after ordering.

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.

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.

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.

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.
