This marker is one of the key indicators of prostate health. It measures a prostate-derived substance in the blood and analyzes it as total and free components. The ratio between them helps differentiate elevations caused by inflammation or age-related changes from those that may require deeper evaluation. It is not a standalone diagnostic tool but a valuable aid for early detection, monitoring treatment response, and assessing long-term progression.
It is a substance produced by the prostate gland, and its level may rise with abnormal activity.
Comparing the free portion to the total amount helps understand the cause of elevation.
