This test will check for the total level of Prostate Specific Antigen (PSA) in the blood, a protein released into the body by the prostate gland.
Increased presence of PSA can indicate possibility of prostate cancer, to be checked with further tests by your GP.
Please avoid strenuous exercise and ejaculation in the 48 hours before the test as this will affect the results. Please do not take biotin supplements for 48 hours before the test. If you are prescribed biotin please speak to your doctor before taking the test.
