Sensitivity measures how often a test correctly generates a positive result for the condition being tested. These measures are not independently validated by the Johns Hopkins Center for Health Security. These tests inform researchers and health providers of the presence of the pathogen, either by amplifying and detecting its genetic material or identifying unique markers of the pathogen itself. If individuals who have the condition are considered "positive" and those who don't are considered "negative", then sensitivity is a measure of how well a test can identify true positives and specificity is a measure of how well a test can identify true negatives: ShelfLife : At least 9 months from date of manufacture. Given the data in hand, it makes sense to say that the probability he is one of the infected is 45/93 = 0.49 or 49%. Sensitivity is calculated based on how many people have the disease (not the whole population).
