PSA BLOOD TEST Meaning and
Definition
-
A PSA blood test is a medical diagnosis tool that measures the level of prostate-specific antigen (PSA) in a person's blood. PSA is a protein produced by the cells of the prostate gland, a small organ located below the bladder in males. This blood test is commonly used to screen for prostate cancer and monitor the progression or recurrence of the disease in individuals who have already been diagnosed.
During a PSA blood test, a small sample of blood is typically drawn from a patient's arm and sent to a laboratory for analysis. The test measures the concentration of PSA in the blood and provides a quantitative value. Elevated PSA levels may indicate the presence of prostate cancer, although they can also be influenced by other conditions such as an enlarged prostate or inflammation.
The results of a PSA blood test are usually reported as nanograms per milliliter (ng/mL). A higher PSA level may prompt a healthcare provider to recommend further diagnostic tests, such as a digital rectal exam or a prostate biopsy, to confirm or rule out the presence of prostate cancer.
It is important to note that while a PSA blood test is a valuable tool, it is not definitive evidence of prostate cancer. False-positive and false-negative results can occur, and the test is often used in conjunction with other diagnostic methods to provide a more accurate assessment of an individual's prostate health. It is essential to consult with a healthcare professional to interpret the results and make informed decisions about further treatment or monitoring.
