Specimen Information

The intended use for this assay is measurement of serum PSA in conjunction with digital rectal examination as an aid in the detection of prostate cancer in men aged 50 years or older. These is also a second indication for this assay, which is serial measurement of PSA to aid in the prognosis and management of patients with prostate cancer; as such, specimens from patients under the age of 50 are not rejected by the laboratory. Interpretation of results, and use of provided reference range (established for the indication of prostate cancer detection in men 50 and older), should take intended uses into consideration.

Patient Preparation

Specimens should be drawn prior to (at least one week) such prostatic manipulations as digital rectal exam (DRE), prostatic massage, transrectal ultrasound (TRUS), and prostatic biopsy. Specimens should be dawn six weeks after a transrectal needle biopsy.
