β-lactam antibiotics such as penicillin G are readily able to form haptens due to the susceptibility of the β-lactam ring to nucleophilic attack by free amino groups, such as those possessed by lysine side chains (Levine and Ovary, 1961). What is an example of a hapten? Hapten is a typeRead More →
Risks to a patient of a false negative test result include: delayed or lack of supportive treatment, lack of monitoring of infected individuals and their household or other close contacts for symptoms resulting in increased risk of spread of COVID-19 within the community, or other unintended adverse events. What toRead More →
Molecular tests are generally more accurate and mostly processed in a laboratory, which takes longer; antigen tests—which are sometimes referred to as ‘rapid tests’—are processed pretty much anywhere, including in doctor’s office, pharmacies, or even at home. How long does it take to get results for COVID-19 antigen tests? AntigenRead More →
The false positive rate — that is, how often the test says you have the virus when you actually do not — should be close to zero. Most false-positive results are thought to be due to lab contamination or other problems with how the lab has performed the test, notRead More →
Some of the at-home antigen tests have an overall sensitivity of roughly 85 percent, which means that they are catching roughly 85 percent of people who are infected with the virus and missing 15 percent. How accurate are rapid COVID-19 antigen tests? Rapid antigen tests are very specific for theRead More →
