LAB3739
Collect
Serum separator tube, pink (K2EDTA), or green (lithium heparin).
Patient Preparation
For patients receiving therapy with high biotin doses (e.g. greater than 5 mg/day), specimen should not be drawn until at least 8 hours after the last biotin administration.
Specimen Preparation
Allow serum separator tube to sit for 15-20 minutes at room temperature for proper clot formation. Centrifuge and separate serum or plasma from cells ASAP or within 2 hours of collection. Transfer 1 mL serum or plasma to an ARUP Standard Transport Tube. (Min: 0.5 mL)
Unacceptable Conditions
Hemolyzed specimens.
