Preanalytics/Notes:	Let blood sample (without additives) coagulate after sampling, centrifuge immediately, remove serum, transfer serum into a new tube, label the tube accordingly, freeze and dispatch deep-frozen with dry ice. Patients receiving high doses of Biotin (> 5 mg/day) should be sampled at least 8 hours after the last aplication, as high levels of the Biotin may interfere with the test system.
