WebMay 9, 2024 · What does low sensitivity high specificity mean? A highly specific test means that there are few false positive results. It may not be feasible to use a test with low specificity for screening, since many people without the disease will screen positive, and potentially receive unnecessary diagnostic procedures. WebJul 15, 2016 · For this screening test you want to set the sensitivity very high, even at expense of a low specificity. This ensures that you will have few false negatives but many false positives. That’s OK. False positives aren’t so bad, they just result in a need for a more expensive and more accurate (but safe) test.” ion orchard ecco
