Previous Next Image >>

This picture shows a blood sample being taken from a patient. A blood sample can be used to test for PSA (Prostate-Specific Antigen). Higher levels of PSA are associated with prostate cancer.

The results are not given immediately. The blood sample must first be sent to a laboratory for analysis.

It is possible to have a high PSA level and not have prostate cancer. PSA levels above 4 ng/ml can prompt a doctor to ask for further tests to be taken which may include a digital rectal examination and a biopsy.
