Medical Laboratory Professionals' Association of Ontario (MLPAO) Practice Exam

Question: 1 / 400

A test for liver function detects impairment in 30% of patients with disease. This test shows:

Poor accuracy.

Low sensitivity.

The test in question demonstrates low sensitivity because it only detects impairment in 30% of patients who actually have liver disease. Sensitivity refers to the ability of a test to correctly identify individuals with a specific condition. In this scenario, low sensitivity means that a significant percentage (70%) of patients with liver disease would not be identified by this test, leading to many cases going undetected.

High sensitivity is desirable for screening tests, as it ensures that most individuals with the condition will receive a positive test result. Therefore, when a test has low sensitivity, it indicates that it may not be the best choice for diagnosing or screening for that particular disease, especially in a clinical setting where detecting all cases is important for patient care and management.
