What is a false negative in the context of screening tests?

In the context of screening tests, a false negative occurs when a screening tool indicates that a patient does not have a condition or issue when, in fact, they do. This means that the screening test yields a negative result (suggesting absence of the condition), but further evaluation reveals that the individual does have the condition.

Option A describes patients who passed the screen but actually aspirated. In this case, the screening test failed to identify the aspiration, leading to a false negative result. The patient appears to be fine based on the results of the test, but they actually experienced a significant health event that went undetected.

This understanding highlights the importance of effective screening tools and the potential risks associated with false negatives. If a screening test does not accurately identify a problem, the patient may miss out on necessary interventions or treatments, which could result in serious consequences.
