Carcinoembryonic Antigen (CEA), Serum/Plasma

Alias:

CEA, Serum, Embryonic Carcinoma Antigen, Carcinoembryonic Antigen (CEA)

Methodology:

Electrochemiluminescence

Performed:

Monday-Friday 8:00a to 10:00p
Saturday-Sunday 9:00a to 5:00p

Analytical Time:

4 hours

Testing Laboratory:

Pathology Laboratory

Laboratory Section:

Core Laboratory

Interpretive Data:

The testing method is an electrochemiluminescence assay manufactured by Roche Diagnostics Inc. and performed on the Cobas system. Values obtained with different assay methods or kits may be different and cannot be used interchangeably.

Carcinoembryonic Antigen (CEA), Serum/Plasma

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

Transport Information:

Centrifuge and aliquot 1.0 mL 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.
