Fasting Required	Specimen Type	Preferred Container/Tube	Acceptable Container/Tube	Specimen Volume	Specimen Minimum Volume (allows for 1 repeat)	Pediatric Minimum Volume (no repeat)
No	Plasma/Serum	Lithium Heparin Plasma Separator Tube (PST)	Lithium Heparin Green Top Tube (GTT), Serum Separator Tube (SST), Red Top Tube (RTT)	0.5 mL	0.4 mL	0.3 mL

GTT/RTT- physically separate plasma or serum from contact with cells as soon as possible of before transport. Separatefrom cells within 30 minutes to minimize uptake of corticosteroids by RBCs

Collection/Processing Instructions

Samples collected in a RTT must be removed from the clot within one hour for storage or transport. Samples collected in gel barrier tubes must be removed from the primary tube prior to transporting to Marshfield. Do not send the primary collection tube.

Specimen Stability Information

Specimen Type	Temperature	Time
Plasma/Serum	Ambient	8 hours
	Refrigerated	2 days
	Frozen	>2 days

Rejection Criteria

Marked Icterus

Interferences

Human Anti-Murine Antibodies (HAMA) may develop leading to test interference in patients receiving murine-based agents for chemotherapy or tumor-imaging studies.

For testing performed at The Diagnostic & Treatment Center lab (Weston Center): High doses of exogenous biotin (also termed Vitamin B7, Vitamin H or Coenzyme R) may interfere with this assay. It is recommended that patients refrain from consuming any multivitamin or supplement containing biotin for at least 72 hours prior to collection of a blood sample.
