An ELISA for Hepatitis C has 95 percent sensitivity and 90 percent specificity. This means that the test
A) detects 90 percent of the true positive samples and has 5 percent false positive results.
B) detects 5 percent of the true positive samples and has 90 percent false positive results.
C) detects 5 percent of the true positive samples and has 10 percent false positive results.
D) detects 95 percent of the true positive samples and has 10 percent false positive results.
E) detects 95 percent of the true positive samples and has 90 percent false positive results.

Sensitivity refers to the ability of a test to correctly identify positive samples, and specificity refers to the ability of a test to correctly identify negative samples. In this case, the ELISA for Hepatitis C has a sensitivity of 95 percent, meaning it correctly identifies 95 percent of true positive samples. It also has a specificity of 90 percent, meaning it correctly identifies 90 percent of true negative samples. Therefore, it has a 10 percent false positive rate (incorrectly identifying negative samples as positive) and a 5 percent false negative rate (incorrectly identifying positive samples as negative). Thus, the ELISA detects 95 percent of the true positive samples and has 10 percent false positive results.
