Question

A new blood test has been developed to screen for disease Z. Researchers establish 50 units as a cut point above which a test is considered positive and thereby indicative of disease. The test manufacturers determine that the test’s sensitivity is unacceptably low. However, the manufacturers are concerned with the specificity and do want to diagnose disease Z more precisely. How can they improve the specificity of the test?They cannot improve this test and should begin work developing a new test.Test each person's blood twice.Lower the cut point below 50 units.Raise the cut point above 50 units.

Answer 1

Option (3).

Step-by-step explanation:

Blood test is mainly performed to identify the particular disease. The different blood composition are measured in blood test and if their values vary out of the normal range, the person confirms the disease.

The new blood test is helpful for the disease determination. The blood test sensitivity can be increased by lowering the cut points below the 50 units. The cut point lowers than 50 only determines the positive test if an individual is actually suffering from the disease.

Thus, the correct answer is option (3).
