Individual tests

Fibrinogen is one of several proteins in the body referred to as clotting factors. These work together to form blood clots and stop bleeding when your body’s tissues or blood vessels are damaged. Fibrinogen testing helps evaluate and monitor symptoms like excessive bleeding or abnormal blockages in veins or arteries.
PSA is a protein made by the prostate, part of the male reproductive system. Most PSA in the blood is bound to serum proteins. A small amount is not protein-bound and is called free PSA. In men with prostate cancer, the ratio of free (unbound) PSA to total PSA is decreased. The lower the ratio, the greater the probability of prostate cancer.
