Prostate Specific Antigen, Total : 0070121

Mnemonic: PSA

Methodology:	Quantitative Electrochemiluminescent Immunoassay
Performed:	Sun-Sat
Reported:	Within 24 hours
Specimen Required:	Collect: Serum separator tube or plasma separator tube. Also acceptable: Plain red, green (sodium or lithium heparin), lavender (EDTA), or pink (K₂EDTA). Specimen Preparation: Allow specimen to clot completely at room temperature. Separate serum or plasma from cells ASAP or within 2 hours of collection. Transfer 1 mL serum or plasma to an ARUP Standard Transport Tube. (Min: 0.5 mL) Storage/Transport Temperature: Frozen. Unacceptable Conditions: Grossly hemolyzed specimens. Stability (collection to initiation of testing): After separation from cells: Ambient: 8 hours; Refrigerated: 5 days; Frozen: 6 months

Reference Interval: 0.0-4.0 ng/mL
Interpretive Data:	The Roche Modular E170 PSA electrochemiluminescent immunoassay is used. Results obtained with different assay methods or kits cannot be used interchangeably. The Roche Modular E170 PSA method is approved for use as an aid in the detection of prostate cancer when used in conjunction with a digital rectal exam in men age 50 and older. The Roche Modular E170 PSA is also indicated for the serial measurement of PSA to aid in the prognosis and management of prostate cancer patients. Elevated PSA concentrations can only suggest the presence of prostate cancer until biopsy is performed. PSA concentrations can also be elevated in benign prostatic hyperplasia or inflammatory conditions of the prostate. PSA is generally not elevated in healthy men or men with non-prostatic carcinoma.
