Description
The PSA Total Blood Test measures the level of total prostate-specific antigen (PSA) in your blood. PSA is a protein produced by the prostate gland and is normally present in low levels in the bloodstream. Elevated PSA levels may signal prostate cancer, but can also be caused by benign prostatic hyperplasia (BPH) or inflammation (prostatitis).
This test is commonly used as a screening tool for prostate cancer and to monitor prostate health in men, especially those over age 40 or with a family history of prostate disease.
Purpose of the Test
- Screen for prostate cancer
- Evaluate symptoms related to enlarged prostate (BPH)
- Monitor PSA levels in individuals with a history of prostate cancer
- Assess prostate inflammation or infection (prostatitis)
- Establish a baseline PSA for future comparison
Who Should Consider This Test?
- Men 40 years or older
- Individuals with a family history of prostate cancer
- Men experiencing:
- Frequent or urgent urination
- Difficulty starting urination
- Weak urine stream
- Pelvic discomfort
- Patients undergoing treatment or surveillance for prostate cancer
What the Test Measures
- Total PSA (Prostate-Specific Antigen):
- Measures the overall concentration of PSA in the blood, which can rise due to prostate cancer, inflammation, or benign enlargement of the prostate.
Common Reasons for Elevated PSA
- Prostate cancer
- Benign prostatic hyperplasia (BPH)
- Prostatitis (prostate inflammation)
- Urinary tract infections
- Recent ejaculation or prostate stimulation
Note: Elevated PSA doesn’t always mean cancer. It is often used as a starting point for further evaluation.
Fasting Required?
No fasting required, but avoid ejaculation and strenuous activity for 24 hours before testing for most accurate results.
