hi anyone at scarleteen,
if i took 1.5 mg of biotin a day or more before a blood draw, probably biotin strepavidin or however it’s called one from quest can that cause a false negative for a blood test 9-11 weeks post event? my urine one was negative too. please let me know i don’t know much about the blood tests
