One of my relative's son has low biotinidise enzyme. He was born 2 weeks ago in USA and is using biotin 5MG tablets now. They are in USA and want to come to Chennai - in 3 months from now [2-June-2015]. They were told that a blood sample needs to be tested for biotin every 6 months to adjust the dosage of Biotin prescribed for the baby. Is Biotin tablets for infants available in Chennai? Is there medical centers/labs/doctors at Chennai who treats such biotin related gene disorder? Any early response is greatly appreciated. Thanks !
