Rotavirus test, Nucleic acid detection test, Isolation in cell culture
The rotavirus test is a stool test used to diagnose a rotavirus infection. Rotavirus affects the intestines and causes vomiting and diarrhea. This infection is especially common in young children, but it can affect adults, too. A rotavirus infection causes a condition called viral gastroenteritis.
A rotavirus vaccine is available for children, but it's possible to get infected even after vaccination. There are many different strains of rotavirus, and the vaccine doesn't protect against all of them. You can also get rotavirus more than once, even if you've had the vaccine.
Rotavirus passes easily from person to person. It can also be picked up by touching a surface contaminated by someone with rotavirus. Sharing food or drink with an infected person can also spread it. Rotavirus can be dangerous, especially in children, because it can cause dehydration. Dehydration happens when the body doesn't have enough fluids, as can happen with frequent diarrhea and vomiting. Most people don't need treatment for rotavirus, but it's still important to diagnose the infection and watch for signs of dehydration.
You may need this test if you have symptoms of a rotavirus infection. Symptoms usually start about 2 days after coming into contact with the virus. They include:
Nausea and vomiting
Belly (abdominal) pain or cramping
Loss of appetite
Symptoms of dehydration include:
Dry mouth and throat
Less urination than usual
Dizziness when you stand up
In children, few or no tears when crying
You may have other tests to diagnose rotavirus or check for dehydration, including urine tests and blood tests.
Many things may affect your lab test results. These include the method each lab uses to do the test. Even if your test results are different from the normal value, you may not have a problem. To learn what the results mean for you, talk with your healthcare provider.
The lab technician looks for the wheel-shaped rotavirus in the sample. If the test results show rotavirus in your stool sample, you have the infection.
It's best to do this test 1 to 4 days after symptoms start, but definitely within 8 days of when you first notice symptoms.
You must collect a stool sample for this test. Your healthcare provider will tell you how to collect a sample in a disposable specimen container with a lid. Do not collect stool from the toilet bowl or put toilet paper into the specimen container.
Give your sample to a healthcare provider or lab technician. At the lab, your stool sample will be tested for the rotavirus.
This test only involves collecting a bowel movement, so there are no risks from this test.
Only having the rotavirus in your digestive tract can cause rotavirus in your stool. Medicines, diet, or lifestyle habits will not affect your results. Be careful not to contaminate the sample with urine or water from the toilet.
You don't need to prepare for this test.
