Preferred Collection Container:

Pathology Laboratory - SST (Serum Separator)
DM Hospitals - Light Green (Plasma Separator Tube)

Also Acceptable Collection Container:

Red (No Additive)
Green No Gel (Lithium Heparin)

Collection Information:

Collect blood in a serum separator or light green plasma separator tube.

Transport Information:

Centrifuge and aliquot 1.0 mL of serum or plasma into a plastic transport vial. Send refrigerated.

Minimum Sample Volume: Minimum amount of analytical sample (serum, plasma, urine, CSF, etc.) required to perform an assay once. Submitting the minimum volume makes it impossible to repeat the test or perform confirmatory or reflex testing. In some situations, a minimum specimen volume may result in a QNS (Quantity Not Sufficient) result, requiring a second specimen to be collected.
