Beta-Human Chorionic Gonadotropin (BHCG), Quantitative, Serum (HCG Tumor Marker)

Preferred Collection Container:

Light Green (Lithium Heparin Plasma Separator Tube)
SST (Serum Separator)

Also Acceptable Collection Container:

Green No Gel (Lithium Heparin)
Red (No Additive)
Plasma from Lavender tubes is acceptable but will not route in the Laboratory Information System (Sunquest)

Collection Information:

Collect blood in a green lithium heparin plasma separator tube or serum separator tube.
Add-on Requests - Requires additional evaluation for acceptability.

Transport Information:

Centrifuge and aliquot 0.6 mL of plasma or serum in 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.
