PSA Free and Total PSA Test in Delhi & Gurgaon

A brief on Prostate Specific Antigen (PSA)

Prostate is a walnut size gland which helps in production of seminal fluid and control of urination in men.

Prostate enlargement is a common problem associated with aging in men & is also known as Benighn Prostatic Hyperplasia.

PSA is a protein produced by normal as well as cancerous cells of the prostate gland. Amount of PSA present in the blood is used as a screening test for prostate cancer, but an increase is also commonly seen in cases of BPH.

PSA exists in both bound and free form in the blood. Total PSA is the total amount of both bound and free form of PSA present in the blood, while free PSA test tells us about the free PSA present in the blood.

Ratio of free and total PSA is a more sensitive indicator of the presence of malignancy as compared to total or free PSA alone. People with benign enlargement of the prostate have a greater proportion of free PSA as compared to those with malignancy. Additionally, PSA levels may change due to intake of antibiotics, a per rectal examination, a prostate biopsy or hormone therapy.

Always consult your physician in case of any increase in your PSA levels.
