Pca3 Test

The PCA3 test, or Prostate Cancer Antigen 3, is a diagnostic tool used to assess the risk of prostate cancer. It detects the levels of a specific RNA molecule associated with prostate cancer in urine samples. It complements traditional prostate-specific antigen (PSA) testing.

Men at risk for prostate cancer, especially those with rising PSA levels or previous negative biopsies, can benefit from the PCA3 test. It aids in making informed decisions about further diagnostic procedures.

A urologist performs a digital rectal examination (DRE) to collect a urine sample from the patient. The urine is then sent to a lab for analysis. The test detects PCA3 RNA levels, which are associated with prostate cancer.

A high PCA3 score may suggest an increased risk of prostate cancer, while a low score indicates a lower risk. It can help determine whether a prostate biopsy is necessary. It's essential to interpret the results in consultation with a urologist.
