4 - Tamaño de grupo variable y prueba perfecta

This method estimates prevalence and confidence limits for variable pool sizes and assumed 100% test sensitivity and specificity. This method should be used if you can be confident that the sensitivity and specificity of the test are both close to 100%, and if pool sizes vary.

For this analysis, it was assumed that samples from 210 individual fruit bats were aggregated into 40 pools of 5 samples each with 10 samples tested individually, that 20 pools and 2 individual samples produced a positive test result and that the test sensitivity and specificity were both 100%. Input values and results for this analysis are summarised in the table below.
