Some misunderstanding about specificity today. 1 false positive out of 102 samples is 99% specificity but with 95% confidence intervals of 95-100%. If there had been no false positives, ie 100% nominal specificity the confidence interval would have still only been 96-100%.
It can only ever be an estimate and needs thousands to be tested to narrow the CI.
In short its as good as it gets.
