real prevalence a technique of measuring prevalence. It is needed because of the significant errors in estimation of prevalence when the definitive test has high sensitivity but low specificity. When Se = selectivity, Sp = specificity, the real prevalence (RP) can be estimated from the apparent prevalence (AP) by the formula: $$\hbox{RP}={\hbox{AP\ +\ S}_{\rm p}-1\over \hbox{S}_{\rm p}+ \hbox{S}_{\rm e}-1}}$$ How to thank TFD for its existence?
