There is value in SnOut particularly as it relates to Clinical Decision Rules and screening tests but there is very little value to SPIN. Let me explain. First of all, sensitivity is the proportion of those who have the disorder who have a positive test. Specificity is proportion of those without the disorder who test negativity. quot;SNOUTquot; amp; quot;SPINquot; Sensitivity rule out OUT amp; Specificity rules IN. sensitivity . .

A rapid antigen test with 80 sensitivity and 99 specificity is used to screen a community of 10 Covid-19 prevalence. The computed NPV and PPV are 97.8 and 89.9 respectively. A repeat test shows that the computed NPV and PPV are 99.5 and 99.9 respectively. May 29, 2016 This is a measure of a test#39;s performance, used to evaluate its overall discriminative power in order to compare it with other tests. YI = sensitivity specificity - 1. For a test with poor diagnostic accuracy, Youden#39;s index equals 0, and in a perfect test Youden#39;s index equals 1. Unfortunately, it does not differentiate the sensitivity and. SPIN and SNOUT.

Sensitivity and specificity are measures of a test#x27;s ability to correctly classify a person as having a disease or not having a disease.

A highly sensitive test means that there are few false negative results, and thus fewer cases of disease are missed.

If 100 with no disease are tested and 96 return a negative result, then the test has 96 specificity. Sensitivity and specificity are prevalence-independent test characteristics,... This has led to the widely-used mnemonics SPIN and SNOUT, according to which a highly SPecific test, when Positive, rules IN disease SP-P-IN,.
