What does a test with high sensitivity indicate regarding disease identification?

A test with high sensitivity indicates that it is particularly effective at identifying individuals who have a disease. This means that the test is capable of correctly identifying a large proportion of people with the condition, leading to a low rate of false negatives. In other words, when a sensitive test yields a negative result, it is highly likely that the disease is truly absent.

This characteristic of high sensitivity makes such tests very useful for screening purposes, where the goal is to ensure that cases of the disease are not missed. The ability to "rule disease out" is particularly emphasized with highly sensitive tests; if the test result is negative, the likelihood that the disease is present is very low. Thus, a common interpretation of a highly sensitive test is that it is excellent at excluding the disease when the result is negative.

The other options do not accurately represent the function of a highly sensitive test. While ruling disease in suggests a confirmation of presence, a highly sensitive test primarily serves to identify those who do have the condition through its ability to catch almost all true cases.
