What is the pca3 test?

Dr. James Eitner

New Cancer Test: The prostate cancer antigen-3 (pca3) test (awaiting approval by the food and drug administration) measures urine levels of the genetic material mrna. High levels of pca3 indicate an increased risk of cancer, and the results of a pca3 test can add reliability to those of a psa test to reduce false positives. Pca3 is available through some labs and can be done if the psa is elevated.
