Specimens with biotin concentrations up to 3ng/mL demonstrated a less than or equal to 10% change in results. Serum biotin concentrations >3 ng/mL may falsely decrease FSH results.
For diagnostic purposes, the results should always be assessed in conjunction with the patient's medical history, clinical examination, and other findings.
