Transcript text: Which of the following is a diagnostic test that measures the level of PSA in a Man's blood?
Digital rectal exam
Prostate biospsy
Protein specific antigen
Prostate-specific antigen
Solution
The answer is the fourth one: Prostate-specific antigen.
Explanation for each option:
Digital rectal exam: This is a physical examination where a doctor inserts a finger into the rectum to feel the prostate gland for abnormalities. It does not measure PSA levels.
Prostate biopsy: This is a procedure where small samples of prostate tissue are removed and examined for cancer cells. It does not measure PSA levels.
Protein specific antigen: This is incorrect because the correct term is "Prostate-specific antigen," not "Protein specific antigen."
Prostate-specific antigen: This is the correct answer. The PSA test measures the level of prostate-specific antigen in a man's blood, which can be an indicator of prostate health.
Summary:
The diagnostic test that measures the level of PSA in a man's blood is the Prostate-specific antigen test.
