Does FDA approval of a new technology guarantee that the test is infallible?

The FDA approval process evaluates the safety and efficacy of medical devices and technologies, ensuring they meet specific standards for use in clinical settings. However, approval does not equate to absolute accuracy or infallibility of the test. Even after receiving FDA approval, tests can still have limitations, including false positives or negatives, variations in patient anatomy, and differences in operator proficiency.

Clinical testing is a complex process, and while FDA approval indicates that a technology has met certain performance benchmarks, it cannot guarantee that it will perform flawlessly in every possible scenario. This is particularly true in areas like mammography, where interpretation can be subjective and influenced by multiple factors. Hence, the understanding that FDA approval does not ensure infallibility is crucial in maintaining realistic expectations about the performance of medical technologies and in promoting continuous quality improvement in clinical practice.
