Dietary supplements containing biotin may interfere in assays and may skew results to be either falsely high or falsely low. For patients receiving the recommended daily doses of biotin, draw samples at least 8 hours following the last biotin supplementation. For patients on mega-doses of biotin supplements, draw samples at least 72 hours following the last biotin supplementation.
Overnight fasting is required.
- Fasting before a blood draw means you don't eat or drink anything except water.
- Your doctor should provide any special instructions related to fasting for your test. Always follow your doctor's instructions.
