A new screening test for colon cancer is developed. The screening test is evaluated by comparing results of 500 patient MRI results (in this case, considered the “gold standard” or confirming diagnostic tool). Of the 264 people who had a positive result on the new test, 211 were confirmed to have the disease by the MRI. Of the 236 people who had a negative result on the test, 97 were confirmed to have the disease by the MRI. Please calculate...

Prostate-specific antigen (PSA) test is a common screening test used for detecting prostate cancer. From Harvard Medical School “Prostate Knowledge” webpage. Is PSA reliable? Although PSA testing can help catch prostate cancer at an early stage, having an elevated PSA (generally considered more than 4 ng/ml) doesn’t necessarily mean that a man has cancer. Noncancerous conditions, including benign prostatic hyperplasia (BPH), or an enlarged prostate, and prostatitis, can raise PSA levels. In fact, studies have shown that about 75% of...

A screening test for breast cancer is used in the same way in two similar populations, population A and population B. The positive predictive value for the screening test in population A is higher than the positive predictive value population B. What is the likely explanation of this discovery? (NOTE: The same test is used the same way in the two populations) (Choose the one best answer) The prevalence of disease is lower in population A than in population B....

Suppose that your company has just developed a new screening test for a disease and you are in charge of testing its validity and feasibility. You decide to evaluate the test on 1000 individuals and compare the results of the new test to the gold standard. You know the prevalence of disease in your population is 30%. The screening test gave a positive result for 292 individuals. Two hundred eighty-five (285) of these individuals actually had the disease on the...

At the first screen, 1132 women were positive on the screening test. All of these positive women had a breast biopsy and 136 were diagnosed with breast cancer. Of the 48,868 who screened “negative” on the...
