Cancer Antigen 125

Container/Tube Type:

Green No Gel (Lithium Heparin)
Light Green (Lithium Heparin Plasma Separator Tube)
Red (No Additive)
SST (Serum Separator)

Preferred Collection Container:

Green No Gel (Lithium Heparin)
Light Green (Lithium Heparin Plasma Separator Tube)

Also Acceptable Collection Container:

Plasma from Lavender tubes is acceptable but will not route in the Laboratory Information System (Sunquest).

Transport Information:

1 mL serum, frozen.

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.
