The diagnostic testing field for COVID-19 is rapidly evolving, with many tests focused on diagnosing patients with active viral infections. Specificity is compounded It may be helpful to define some terms here. 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: rY,a K^`#G+s.#GO`?Ogggg[[[[[rbrbrbrb\2K9=(zPAe=(z0`lp6:glp6:gO,&n'[Jy;ybv}J* Definitely not to be ignored.
