Prostate-Specific Antigen (PSA)

What is Prostate-Specific Antigen (PSA)?
Prostate-specific antigen (PSA) is a glycoprotein closely related to the glandular kallikreins, primarily produced by the prostate gland. It plays a crucial role in the diagnosis and monitoring of prostate health, especially in men over 50.

Causes of Elevated PSA Levels
Increased PSA levels in the blood are commonly linked to prostate-related conditions such as prostatitis, benign prostatic hyperplasia (BPH), or prostate cancer. However, PSA is also found in para-urethral and anal glands, and in some cases, in breast tissue or with breast cancer—meaning that low levels may also appear in female patients.

PSA Testing After Prostate Surgery or Treatment
PSA may still be detectable in the blood even after a radical prostatectomy. The decline in PSA levels after treatments like radiotherapy, hormone therapy, or prostate removal can indicate how successful the treatment has been. A rapid fall in PSA levels is typically a positive sign.

Other Factors That Influence PSA Levels
Inflammation, physical trauma, or medical procedures involving the prostate can temporarily raise PSA levels. Situations like urinary retention, rectal examinations, cystoscopy, colonoscopy, prostate biopsy, or laser treatments may all contribute to short-term fluctuations in PSA readings.

Private PSA Testing in Slough and Nearby Locations
Comprehensive PSA blood testing is available for men in Slough, Windsor, Maidenhead, and surrounding Berkshire areas. This test helps monitor prostate health, detect abnormalities early, and assess the effectiveness of prostate cancer treatments.
