SARS CoV 2 Tests True Risk

by Agustin X


The Positive Predicted Value (PPV) and the Negative Predicted Value (NPV) of a clinical test are necessary to inform accurate medical decisions and to guide behaviors that directly affect the user and its community (e.g. COVID-19). The PPV / NPV vary profoundly depending on the Specificity and Sensitivity of each test and the ever changing Prevalence of the disease at a given geographical area. This program will provide the Patient / Practitioner with the PPV or NPV for a particular clinical test (e.g. Elecsys from ROCHE for detecting SARS-Cov-2 / COVID-19) in a particular geographical location (e.g. California) for the exact date the test was administered.
