Vitamins and minerals are micronutrients that support many crucial body functions. At-home tests can check for deficiencies, but a person should not make health decisions based on their results without input from a doctor.

A quick look at 6 of the best at-home vitamin deficiency tests

Although the Dietary Guidelines for Americans 2020–2025 indicate that a person must aim to meet their vitamin and mineral needs through their diet, sometimes they may need a multivitamin to supplement their intake.

When a person develops a nutritional deficiency, the body may produce symptoms, some of which can go unnoticed. Though an at-home test should not substitute for a doctor’s or registered dietitian’s advice, it may indicate missing nutrients in a person’s diet.

The Centers for Disease Control and Prevention (CDC) lists several of the most common deficiencies in the United States. These include:

High risk groups

A 2019 research review showed specific groups of people with a higher risk of developing vitamin or mineral deficiencies. The groups included:

  • undernourished people
  • older adults

  • adolescents
  • young children

The researchers write that addressing these deficiencies should include improved, more diverse diets, and supplementation.

A person interested in seeing if they may have a vitamin deficiency can purchase a home-testing kit to check for possible deficiencies. However, it is important to consider the pros and cons of these services.


  • The test kits are convenient.
  • The results are confidential.
  • The test kits are easy to use.
  • Tests often come in discrete packaging.
  • The tests include complete instructions for providing a sample.
  • A person can get their results quickly with certain companies.


  • People may still have to contact a doctor if the results show a deficiency.
  • People may have to contact a doctor if they have symptoms but a negative test result.
  • At-home tests can be expensive, and it may be more cost-effective to go directly through a lab.
  • It can take up to 2 weeks to get results.

People may wish to consider these factors before buying a test online:

  • The nutrients tested: Many companies offer comprehensive panels, which test for several vitamins and minerals. However, some tests only check the levels of certain vitamins. A person should pick the test that best suits their needs.
  • The collection method: Anyone uncomfortable drawing a finger-prick blood sample may prefer a test that relies on a saliva sample instead. However, many vitamin and mineral tests require a blood test.
  • Fasting: Some tests require a person to fast before taking a sample. A person should check the fasting period before taking the test. They may also require people to stop taking certain supplements for a few days before collecting a sample.
  • The timing of results: Some tests have shorter turnaround times, but these may be more expensive.
  • Price: Different at-home vitamin deficiency tests fit different budgets. Those that test for a wider range of vitamins may cost more.

According to the CDC, the most common deficiencies are in vitamin B6, iron, and vitamin D. Therefore, a person may wish to test for these vitamins. Iron deficiencies were most common in adult females, but they may also be present in children aged 1–5 years.

Typically, an at-home vitamin test will include instructions on how to take the test, the sample collection kit, and shipping labels and packaging.

A finger-prick blood sample kit will include several lancets, a collection tube, alcohol wipes, bandages, and instructions.

If a test shows that a person has a vitamin deficiency, it is important that they contact a doctor. A person may also wish to inform a doctor if their test does not show a particular deficiency.

If a person receives treatment from a doctor, they may wish to conduct the test again after their treatment ends to see how their vitamin levels change.

It is advisable for a person to avoid making health decisions based on the results of an at-home test without first consulting a doctor.

The FDA states that at-home tests can be an effective way to detect health conditions and monitor existing ones. However, it warns people should not replace doctor’s appointments with at-home tests.

The most reputable companies selling at-home tests send customers’ samples to CLIA-certified labs. These are the labs that hospitals and doctor’s offices use, which may suggest the sample analysis will be as accurate as it is for tests people will get from a doctor.

However, there is a risk of people making mistakes or contaminating their samples when they collect them at home. Those uncomfortable collecting their own sample may wish to visit an in-person testing center.

Regardless of the results of an at-home vitamin deficiency test, a person may want to consider consulting a doctor. If their results are positive for a deficiency, a doctor will likely double-check them, run other appropriate tests when needed, and help diagnose any underlying cause before setting out a treatment plan.

If an individual’s results are negative, but they are still experiencing symptoms of a vitamin or mineral deficiency, a doctor may carry out further tests to diagnose any underlying conditions.

A person should not treat a vitamin or mineral deficiency without discussing it with a doctor.

Below, we answer some of the top frequently asked questions about vitamin deficiency tests.

Are at-home vitamin deficiency tests accurate?

The accuracy of a vitamin deficiency test depends on the company, the sample collection, and various procedures. If the company designs its devices in line with medical guidelines and people take their samples correctly, the test results may be accurate.

The Food and Drug Administration has a list of approved at-home tests, and anyone concerned about accuracy may prefer to use one.

To help ensure accuracy, carefully follow the instructions about taking, storing, and sending off samples.

Who should use an at-home vitamin deficiency test?

Anyone who thinks they may have an imbalance in vitamin or mineral levels should speak with a healthcare professional.

An at-home vitamin deficiency test is a useful alternative if a person cannot easily access healthcare services due to location, health, or insurance coverage, but they should not replace regular doctor appointments.

What should I do if I have a deficiency or excess of a vitamin or mineral?

A person should speak with a healthcare professional to understand the reason for any vitamin or mineral excess or deficiency before deciding on a treatment.

Genetics, prescription medications, and other factors can affect levels of vitamins and minerals in the body, and a healthcare professional will consider these.

Some at-home testing companies provide supplements on a subscription basis to help treat a vitamin deficiency.

What causes a vitamin deficiency?

In most cases, a vitamin deficiency stems from not having enough nutrients in the diet.

People who are most at risk of developing a vitamin deficiency are people with malnourishment, older adults, pregnant people, teenagers, and young children.

How can I tell if I have a vitamin deficiency?

The specific symptoms of a vitamin deficiency will depend on which vitamin deficiency a person has.

For example, a vitamin C deficiency can cause dental problems, bone fractures, dry eyes, and hair loss. An iron deficiency can cause fatigue, while a lack of vitamin D can be responsible for muscle twitches, fatigue, and osteoporosis.

A person should speak with a doctor about their symptoms before getting a vitamin deficiency test.

How can I get my vitamin levels checked?

There are two main ways a person can get their vitamin levels checked. A person can contact a doctor, who will order the test and help the person provide a sample. Or, they can order an at-home test and complete the test themselves.

It is important for a person to always discuss their reasons for testing and their test results with a doctor before making any health decisions.

Does CBC test for vitamin deficiencies?

A complete blood count (CBC) test can pick up vitamin deficiencies. A person can get this test from a doctor.

At-home vitamin deficiency tests check levels of vitamins and minerals in a blood or saliva sample. They are generally convenient, but they can be expensive.

Anyone concerned about a deficiency may want to consider consulting a doctor, especially if a test returns a positive result. The doctor can check for any underlying health conditions, perform further tests, and offer treatment if needed.
