A new blood test to detect prostate cancer by measuring prostate specific antigen (PSA) was given to 1,000 male members of a large HMO. Although 50 of the men actually had prostate cancer, the test was positive (PSA> 4 ng/mL) in only 15; the other 35 patients with prostate cancer had negative tests. Of the 950 men without prostate cancer, the test was positive in 200 men and negative in 750. What is the positive predictive value of this blood test?
