Prognostication and monitoring in NSCLC.
Quantitative Enzyme-Linked Immunosorbent Assay
The level of CYFRA 21-1 cannot be used as absolute evidence for the presence or absence of disease.
Plain red or serum separator tube.
Allow serum specimen to clot completely at room temperature. Separate serum from cells ASAP or within 2 hours of collection. Transfer 1 mL serum to an ARUP Standard Transport Tube. (Min: 0.5 mL)
Plasma. Icteric, lipemic, or hemolyzed specimens.
After separation from cells: Ambient: 48 hours; Refrigerated: 2 weeks; Frozen: 2 months (avoid repeated freeze/thaw cycles)
This assay is performed using the Fujirebio Diagnostics CYFRA 21-1 Enzyme Immunoassay. Results obtained with different assay methods or kits cannot be used interchangeably. Results cannot be interpreted as absolute evidence of the presence or absence of malignant disease.
