A Novel Biomarker for the Early Identification of Invasive Stomach

A novel biomarker for the early identification of invasive stomach cancer has been found. When compared to endoscopy with several biopsies, it offers a sensitivity of 89 percent and a specificity of 85 percent. The test is employed in two populations: one in the United States, where 5 out of 100,000 people have stomach cancer, and another in China, where 100 out of 100,000 people have the disease. Which of the following statements about this new test is the most accurate?

A) Negative predictive value of the test is lower in the American population
B) Positive predictive value of the test is higher in the Chinese population
C) Sensitivity of the test is higher in the American population
D) Specificity of the test is higher in the Chinese population
E) The test is not reliable in the American population
