What is Serial Testing?
COVID-19 Serial testing is when one person tests themselves multiple
times for COVID-19 on a routine basis, such as every day or every other
day. By testing more frequently, you may detect COVID-19 more quickly
and reduce spread of infection. Serial testing (i.e. testing every day or
every other day) is more likely to detect COVID-19, especially when you
do not have any symptoms.
What is the difference between
an antigen and molecular test?
An antigen test, such as the QuickVue At-Home OTC COVID-19
Test, detects proteins from the virus. Molecular tests detect
genetic material from the virus. Antigen tests are very specific for
the virus, but not as sensitive as molecular tests. This means that a
positive result is highly accurate, but a negative result does not
rule out infection. If your test result is negative, you should
discuss with your healthcare provider on whether an additional
test is necessary and if you should continue isolating
at home.
There is a higher chance of false negative results with
antigen tests than with laboratory-based molecular tests.
This means that there is a higher chance this test will give
you a negative result when you have COVID-19.
How Accurate is this Test?
Based on the interim results of a clinical study where the
QuickVue At-Home OTC COVID-19 Test was compared to an
FDA
authorized molecular SARS-CoV-2 test, QuickVue
At-Home OTC COVID-19 Test correctly identified 83.5% of positive
specimens and 99.2% of negative specimens.
The performance of this test is still being studied in patients without signs
and symptoms of respiratory infection and
for
serial
screening.
Performance may differ in these populations
