Additional Information
Serial monitoring should use only one method.
Biotin Therapy may invalidate results. Some assays may exhibit interference when samples are collected from patients consuming higher than recommended doses of biotin or supplements (including prenatal multivitamins), which also contain biotin. Simple daily supplementation, recommended dosage, is not problematic. It is recommended that all patients be asked if they are consuming high-dose biotin or biotin containing supplements. Patients should be cautioned to stop using biotin-containing supplements at least 72 hours prior testing.
