Reference Range
<0.10 ng/mLAfter radical prostatectomy
≤4.0 ng/mLIn healthy males without prostatectomy


Clinical Significance
For post-prostatectomy patients.
The lower limit of accurate quantification for this assay is 0.02 ng/mL. PSA values less than 0.02 ng/mL cannot be accurately measured and will be reported as less than 0.02 ng/mL. Specimens with PSA levels below the lower limit of accurate quantification should be considered as negative. In patients with a negative result for post-prostatectomy PSA, serial monitoring of PSA levels at regular intervals, along with physical examinations and other tests, may help to detect recurrent prostate cancer.
