Clinical Significance

No sample should be collected on patients receiving therapy with high biotin doses(i.e. biotin therapy for Multiple Sclerosis or oncology patients; skin, hair and nail supplements, or multivitamins containing > 5 mg/day) until at least 12 hours after the last biotin administration. If unsure, or if the clinical picture does not fit the results please contact the laboratory. We have methods to check for biotin interference as well as for any other interferences and for the accuracy of the results.

Biotin interference would falsely decrease the result of this assay.
