What does a D rating from the UPSTF tell about the benefit of a particular health screening?

• A. The service is universally recommended
• B. There is moderate/high certainty the service has no net benefit or the harms outweigh the benefits
• C. The benefit is uncertain
• D. The service provides a small benefit

Answer: (B)

Think of the rating as a clear signal about overall value in the general population. A D rating means the evidence shows, with moderate to high certainty, that the screening provides no net benefit or that the harms of screening outweigh the benefits. In other words, routine screening should not be offered or recommended because the downsides—such as false positives, unnecessary procedures, anxiety, or other harms—override any potential advantage. This guides clinicians to avoid recommending the test in typical care, reserving any discussion only for special, individual circumstances where the balance might be reconsidered.
