The importance of total and free psa testing

The Significance of Free PSA

[style=color:#282828]PSA circulates through the body in two ways; bound to other proteins or by itself. Unbound PSA is called free PSA. A free-PSA test will measure the percentage of unbound PSA while a PSA test is used to measure the total of free and bound PSA in the blood (6).

[style=color:#282828]The free PSA is a defective variant of normal PSA that can no longer bind to other proteins and so circulates in the blood in the free form. Although the reason why is poorly understood - patients with cancer may have lower free PSA levels than those with a benign prostate condition (6).
