COVID-19 Testing Group
The COVID-19 Testing Group is a community resource for sharing COVID-19 prevalence, seroprevalence, and burden studies, as well as planning tools and data. This website is maintained by the Larremore Lab at the University of Colorado, Boulder and the Grad Lab at the Harvard T.H. Chan School of Public Health.
Prevalence calculator
with known sensitivity and specificity
This calculator is one of multiple resources available through the COVID-19 Testing Group. It accompanies the preprint "Estimating SARS-CoV-2 seroprevalence and epidemiological parameters with uncertainty from serological surveys". This work is not yet peer reviewed.
Given test results in a population sample, using a test with known sensitivity and specificity, what is the posterior distribution of prevalence in the population?
| # positive tests | |
|---|---|
| # negative tests | |
| Sensitivity | |
| Specificity |
