The city council has asked you, a nurse leader, to serve on a COVID-response committee to select the COVID antigen test they plan to use for mass testing. Four different tests, by 4 different manufacturers, are under consideration. The tests’ sensitivity ranges from 31 to 99 percent. Specificity range ranges from 85 to 99, shown in the table below.
The council knows you are great nurses and trust your judgment. They would like you to explain what a negative test and a positive test means and to help the council decide on which test to purchase.
