Consider the Covid-19 global prevalence as 0.02. However, the analytic performance of PCR based tests is good where PCR based Covid-19 test has 80% Specificity and 75% Sensitivity. A patient underwent a first Covid-19 test and he got the test result as positive. He underwent a second Covid-19 test and again he got the test result as positive. To make sure the both tests, he underwent the third test and surprisingly we got positive again. What is the probability of having Covid-19 of that patient?
