Biotin interferes with B12 testing
LabCorps, the medical diagnostics company that dominates blood testing recommends patients and physcians discuss biotin supplements if a B-12 test is ordered. See below for specific test and recommendation to pause your biotin supplement 72 hours prior to your test.
Biotin is a popular supplement for consumers who want healthy hair, nails, and teeth. Biotin also interferes with at least one B-12 level test.
Wondering if it is true?
It is accepted that signs of biotin deficiency include skin rashes, hair loss, and brittle nails.
And it is also true that National Institutes of Health would prefer further research before marketing biotin as a better hair, skin, and teeth vitamin.
Biotin and Health
Hair, nail, and skin health
Signs of biotin deficiency include skin rashes, hair loss, and brittle nails [10,13]. Therefore, biotin supplements are often promoted for hair, skin, and nail health [17,24,25]. However, these claims are supported, at best, by only a few case reports and small studies.
Future studies are needed to determine whether biotin supplements might improve hair, nail, and skin health, especially among healthy individuals.

We set out to make a better biotin.
Multi-Biotin is a biotin supplement designed with Folate + A, C, D, E, and B vitamins and zinc.
This test may exhibit interference when sample is collected from a person who is consuming a supplement with a high dose of biotin (also termed as vitamin B7 or B8, vitamin H, or coenzyme R). It is recommended to ask all patients who may be indicated for this test about biotin supplementation. Patients should be cautioned to stop biotin consumption at least 72 hours prior to the collection of a sample.
