<p class="p__0">Studiesexternal icon have actually revealed that antigen tests have similar sensitivity to laboratory-based NAATs when viral load in the specimen is high and the person is likely to be most infectious. Keep Checking Back Here of antigen tests is normally as high as the majority of NAATs, which means that incorrect positive test outcomes are not likely when an antigen test is used according to the manufacturer's directions.</p>

<p class="p__1">In general, for all diagnostic tests, the lower the frequency of infection in the community, the greater the proportion of false positive test outcomes. Favorable and negative predictive worths of all in vitro diagnostic tests (e. g., NAAT and antigen tests) vary relying on the pretest possibility. Pretest likelihood thinks about both the frequency of the target infection in the population that is being tested along with the scientific context of the individual being evaluated.</p>

<p class="p__2">If the prevalence of infection in the neighborhood is low, and the person being tested is asymptomatic and has actually not had any known contact to an individual with COVID-19, then the pretest probability is usually considered low. See CDC's Interpreting Results of Diagnostic Tests for extra info on the relationship in between pretest probability and the likelihood of positive and negative predictive values.</p>
<br>
<p class="p__3">In addition, state health departments usually release COVID-19 data on testing positivity rates and case rates for their neighborhoods. Processing of Antigen Tests for SARS-Co, V-2 The Conditions of Authorization in the antigen EUAs define that CLIA-certified labs and screening websites are to follow the manufacturer's guidelines for use, generally found in the bundle insert, when performing the test and checking out test results.</p>
