PCA3 Urine Test for Prostate Cancer
The PCA3 test for the detection of prostate cancer is highly specific and more precise than all other available screening tests for prostate cancer. The PCA3 test is a new gene‐based test that is performed on a urine sample. Unlike PSA, the PCA3 result is not elevated when a man suffers from a disease that increases the size of the prostate such as BPH or prostatitis. PCA3 is specific to prostate cancer. Therefore, it gives very useful information, in addition to PSA, in deciding if a biopsy is really needed.
