Expert Answer :
The purpose of newborn screening is to identify the babies who otherwise would have shown symptoms later detrimental to their development or survival. It is like TSH is elevated - do we treat them with Thyroxine for life long assuming that they have congenital hypothyroidism_? No = similarly you can`t assume and treat them - just because biotin is cheaper - you need to confirm the diagnosis - this is what Kills the Newborn screening programme!

Please start biotin and repeat level at 3 months or as possible after 3 days of absteinence.
biotin supplementation wont harm wheras withholding it in positive report may raise medico legal concern.
hope this helps.
