Definition of Rotavirus antigen test:

The rotavirus antigen test detects rotavirus in the feces. Rotavirus is the most common cause of infectious diarrhea in children.

How the test is performed:

There are many ways to collect stool samples. You can catch the stool on plastic wrap that is loosely placed over the toilet bowl and held in place by the toilet seat. Then you put the sample into a clean container. One type of test kit supplies a special toilet tissue to collect the sample, which is then placed in a container.

For infants and young children wearing diapers, try lining the diaper with plastic wrap. If the plastic wrap is positioned properly, it will help prevent urine and stool from mixing to provide a better sample.

The sample should be collected during the acute phase of the infection, which is the period in which diarrhea is occurring.

The sample is taken to the laboratory for evaluation.

How to prepare for the test:

No special preparation is necessary for this test.
