Vitamins and minerals are micronutrients that provide support for many crucial functions throughout the body. If a person has concerns over their vitamin and mineral levels, they can use an at-home test to check for deficiencies.

When a person develops a nutritional deficiency, the body may produce signs and symptoms, some of which can go unnoticed. Though an at-home test should not act as a substitute for a doctor or nutritionist’s advice, it may indicate missing nutrients in a person’s diet.
High risk groups
- undernourished people
- older adults
- people who are pregnant
- young children
A person interested in seeing if they may have a vitamin deficiency can purchase a home-testing kit to check for possible deficiencies.
At-home tests offer convenience, confidential results, and ease of use. However, as with most at-home tests, the main drawback is that a person will still usually need to contact a doctor if their test results show a deficiency. They may also need to visit a doctor if they have symptoms but the test comes back negative.
An at-home test can sometimes be expensive, depending on the brand. An individual may sometimes find it more cost-effective to go directly through a lab, which sometimes bills their insurance provider directly.

Regardless of the results of an at-home vitamin deficiency test, a person should consider consulting a doctor. If their results are positive, a doctor will likely double-check the the results, run other appropriate tests when needed, and help diagnose any underlying cause of the deficiency 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 attempt to treat a vitamin or mineral deficiency without first discussing it with a doctor.
Here are some of the most common questions about these tests.
Are at-home vitamin deficiency tests accurate?
The accuracy depends on the company, the sample collection, and various procedures. If the company has designed its devices in line with medical guidelines and people take their samples correctly, the test results may be accurate.
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 that they may have an imbalance in vitamin or mineral levels should consider speaking with a healthcare professional.
If a person does not have access to healthcare or cannot leave the house, for example, an at-home vitamin deficiency test is a useful alternative.
What should I do if I have a deficiency or excess of a vitamin or mineral?
Some at-home testing companies provide supplements on a subscription basis. However, due to a company’s interest in making profits, there are concerns about bias.
A person should consult 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
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 should consult a doctor, especially if a test returns a positive result. The doctor can check for any underlying health issues, carry out further tests, and offer treatment, if needed.
