Will biotin affect my results?

Biotin does not affect hormone levels in the body, but it may interfere with how hormone levels are measured in the lab. With traditional venipuncture (blood draw) tests, this interference can sometimes make results appear abnormal even when hormone levels are actually normal.

The laboratories that perform hormone testing for Everlywell use similar assays to those used by healthcare providers. However, our partner labs have not yet conducted studies to determine the specific impact of biotin on their testing methods. Because of this, we cannot say with certainty how biotin may affect your Everlywell hormone test results.

We recommend speaking with your healthcare provider before making any changes to your medications or supplements.
