PSA (Prostate Specific Antigen) - Total – BC265
♂️ Prostate Health ScreeningReport: Same Day
Sample Type: Blood (Serum)
Test Code: BC265
The Total Prostate Specific Antigen (Total PSA) test is a fundamental blood test used to screen for prostate health issues. PSA is a protein produced by cells of the prostate gland. Elevated levels in the blood can be an early indicator of potential problems, including prostate cancer.
✔ The primary screening tool for prostate cancer, especially in men over 50.
✔ Helps in the detection of other prostate conditions like Benign Prostatic Hyperplasia (BPH) and prostatitis.
✔ Used to monitor the effectiveness of prostate cancer treatment.
✔ Important to follow preparation instructions to ensure accuracy.
Total PSA: A Key Marker for Men's Health
The prostate is a small gland in men that is part of the reproductive system. It produces Prostate Specific Antigen (PSA), which is a normal component of semen. A small amount of PSA naturally leaks into the bloodstream. When the prostate gland's architecture is disrupted—due to enlargement, inflammation, or cancer—more PSA can escape into the blood, causing the level to rise.
The Total PSA test measures the sum of all PSA in the blood (both the "free" form and the form "bound" to other proteins). It is a highly sensitive but not perfectly specific test, meaning an elevated level is a red flag that warrants further investigation but is not, by itself, a diagnosis of cancer.
Interpreting Your Total PSA Level
Generally, a lower PSA level is better. However, what is considered "normal" can depend on age, as the prostate naturally enlarges over time.
- Low PSA (e.g., < 4.0 ng/mL): Typically considered normal, though this threshold can be lower for younger men. The risk of prostate cancer is low.
- Borderline or "Gray Zone" PSA (4.0 - 10.0 ng/mL): An elevated level in this range could be due to cancer, but is more often caused by Benign Prostatic Hyperplasia (BPH) or prostatitis (inflammation of the prostate). This is where a follow-up test like the **Free PSA** becomes very important to help stratify the risk.
- High PSA (> 10.0 ng/mL): A level in this range is associated with a significantly higher probability of prostate cancer, and a urologist will almost certainly recommend further investigation, such as a biopsy.
It's crucial to discuss your results with your doctor, who will interpret them based on your age, family history, and other clinical factors.
Frequently Asked Questions (FAQ)
PSA is a protein produced exclusively by the prostate gland. A small amount is normally found in the blood. The Total PSA test measures this amount and is used as a primary screening tool for prostate health.
Not necessarily. While prostate cancer is a primary concern, other common, non-cancerous conditions like an enlarged prostate (BPH) or inflammation (prostatitis) are frequent causes of an elevated PSA. A high level is a signal for further investigation.
Screening guidelines vary, but discussions with your doctor about PSA testing should typically begin around age 50, or earlier (age 40-45) if you have a family history of prostate cancer or are of African descent.
To ensure an accurate result, you should avoid ejaculation and vigorous exercise (especially cycling) for at least 48 hours before the blood draw. Also, let your doctor know if you have had a recent urinary tract infection or prostate exam.
