How Do COVID-19 Antigen Tests Work?
2
What Is a Rapid
COVID-19 Antigen Test?
COVID-19 antigen tests require a sample of cells
that come from your upper respiratory tract. In
particular, they can be taken from inside your
nose or from your nasopharynx, which is the top
part of the throat that is behind the nose. The
test sample is taken using a cotton swab that is
inserted into your nostril.

Before The Test
-Diagnosis is testing once a person has shown
symptoms of a disease or has a known exposure to
a disease. An antigen test can be used for
diagnosis in people who have symptoms consistent
with COVID-19. -Screening is looking for a
disease in people who dont have any signs or
symptoms. Because antigen tests can be performed
rapidly and at a relatively low cost, they may
be used in large screening programs that involve
repeatedly testing people to help prevent the
spread of Covid.

During The Test
Whether taken in a medical setting or at-home,
the test sample is obtained by inserting a
cotton-tipped swab into your nostril. The sample
may be taken from lower in your nose, or the
swab may go toward the back of your nose. Once
the swab is inserted, it is usually rotated, and
a sample is often taken from both nostrils. -It
takes under a minute to take the test. The
insertion of the swab into your nose can be
uncomfortable, especially when a sample is being
taken from your nasopharynx. -There may be a
temporary sting or need to cough, and you may
feel your eyes water.

After The Test
There are no special post-test procedures, and it
is rare to have any lasting effects after your
test sample is taken. -If you are having a
point-of-care test, your sample will be
immediately analyzed to detect viral
antigens. -If you are taking an at-home test, you
will need to follow the specific instructions
for carrying out this part of the test analysis.
