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). Simple daily supplementation, recommended dosage, is not problematic. It is recommended that 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 collection.
NUlirt packing list or NPHL Test Order Form (completed in entirety) must accompany the specimen.
