What will be the sensitivity, specificity, PPV and NPV of two diagnostic tests? Total samples 113 .Microscopy 71 +ive 42 -ive, PCR 110 +ive 3 -ive?

20 May 2019 1 3K Report

Basically i am working on diagnostic sensitivity of two test, How sensitive and specific PCR is over microscopy.

Hello, You need to provide all four values, true positive, true negative, false positive and false negative. Then only we can calculate Sen;Spe;PPV;NPV.

The complete 2x2 table is required to calculate all of them
