Hepatitis B Surface Antigen Confirmation

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 lithium heparin plasma separator tube or serum separator tube.

Transport Information:

Centrifuge and aliquot 1.0 mL of plasma or serum into a plastic 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.
