total PSA

total PSA

A “raw” PSA serum level (4-10 ng/mL) (as well as a normal digital rectal examination) on which a  doctor will base his or her decision to refer a patient for a prostate biopsy. There is a 20-30% cancer detection rate at a PSA of 4-10 ng/mL.

Veltri and colleagues measured serum total PSA, free PSA and pro-PSA, performed a digital rectal examination semiannually and conducted a surveillance biopsy examination each year.
Instead, the decision to biopsy should be based on other factors, including free and total PSA, PSA velocity and density, age, family history, race or ethnicity, previous biopsy results and co-morbid conditions.
The decision to proceed to prostate biopsy should be based not only on PSA and DRE results, but should take into account multiple factors including free and total PSA, patient age, PSA velocity, PSA density, family history, ethnicity, prior biopsy history and co-morbidities.

A preliminary study found that when total and free PSA were measured in solutions of the 90% PSA-ACT and 10% free PSA (90: 10 PSA) material from Stanford/ WHO, the slope of the regression line that compared the measured free PSA to measured total PSA was 0.
The ratio of free to total PSA in serum has been demonstrated to significantly improve the differential of prostate cancer from benign prostatic hyperplasia (BPH).
One way to determine whether a rising PSA level is due to prostate cancer is to assess the free: total PSA ratio, which is now offered by several labs.
For a man in his mid- to late 40s, even a small elevation in total PSA markedly increased the risk of later being diagnosed with a metastatic or clinical stage T-III or more advanced prostate cancer, said Andrew J.
