What does 100% sensitivity in a test mean?

The test identifies all negative cases
The test identifies some positive cases
The test identifies all positive cases
The test cannot identify any cases

The correct answer is: The test identifies all positive cases

100% sensitivity in a test means that the test identifies all positive cases correctly. This means that if a test has 100% sensitivity, it will not produce any false negative results. Sensitivity is a measure of how well a test can correctly identify those individuals who have the disease or condition that is being tested for. In this case, since the test with 100% sensitivity can identify all positive cases, it is the correct choice. Option A is incorrect because 100% sensitivity does not relate to identifying negative cases; it is about correctly identifying positive cases. Option B is incorrect because 100% sensitivity does not imply that only some positive cases are identified; rather, it means all positive cases are identified. Option D is incorrect because 100% sensitivity does not mean that the test cannot identify any cases; it means that it can identify all positive cases accurately.
