Useful as a biomarker of various CNS pathologies and as a tumor marker for malignant melanoma.
Quantitative Enzyme-Linked Immunosorbent Assay
Serum separator tube or plain red.
Allow serum specimen to clot completely at room temperature. Separate serum from cells ASAP or within 2 hours of collection. Transfer 2 mL serum to an ARUP Standard Transport Tube. (Min: 0.5 mL)
After separation from cells: Ambient: 24 hours; Refrigerated: 1 week; Frozen: 3 months
This assay is performed using the CanAg® S100 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.
