Can Biotin Affect A Drug Test?

Will biotin show up on a drug test? Biotin, AKA vitamin B7, appears to significantly throw off the results of certain lab tests. The FDA has issued a Safety Communication about biotin, also known as vitamin B7. Taking high levels of it can significantly interfere with certain lab tests, rendering the results incorrect.

How long before lab tests should I stop taking biotin? It is recommended that patients who have consumed 5–10 mg biotin wait a minimum of 8 hours before having blood collected for laboratory tests (29, 40, 49). Longer washout periods, up to 72 hours, may be required to prevent interference in assays with interference thresholds <30 ng/mL (<122.8 nmol/L) (29). What supplements can cause a false positive drug test? In addition to prescription medications, these other common substances can lead to a false positive drug test.
