Initial biotinidase enzyme test to diagnose or rule out biotinidase deficiency.
A control specimen needs to be sent with the patient specimen. The control specimen needs to be drawn from a normal, healthy individual who is not biologically related to the patient. Collect control specimen within 30 minutes of patient specimen.
Plain red or serum separator tube (patient) AND plain red serum separator tube (control).
