Test Code LAB116 Prostate Specific Antigen (PSA), Diagnostic

Important Note

For PSA screening testing order LAB5381

For PSA diagnostic testing order LAB116

Useful For

Elevated serum PSA concentrations have been reported in patients with prostate cancer, benign prostatic hypertrophy or inflammatory conditions of other adjacent genitourinary tissues, but not in apparently healthy men, men with non-prostatic carcinoma, apparently healthy women or women with cancer.  PSA may serve as an accurate marker for assessing response to treatment in patients with stages B2 and D1 prostatic cancer.  Serial measurement of PSA concentrations can be an important tool in monitoring patients with prostatic cancer and in determining the potential and actual efficacy of surgery and other therapies.  This test measures total PSA (see notes regarding free PSA).

 

Results from other manufactures or methodologies may vary in concentrations due to differences in reagent specificity and should not be used interchangeably. When performing serial samples over time, it is recommended that the same method be used, unless “re-baselined” with another method.
