What is a strep A test?Strep A, also known as group A strep, is a type of bacteria that causes strep throat and other infections. Strep throat is an infection that affects the throat and tonsils. The infection is spread from person to person through coughing or sneezing. While you can get strep throat at any age, it's most common in children 5 to 15 years old. Show
Strep throat can be easily treated with antibiotics. But left untreated, strep throat can lead to serious complications. These include rheumatic fever, a disease that can damage the heart and joints, and glomerulonephritis, a type of kidney disease. Strep A tests check for strep A infections. There are two types of strep A tests:
Other names: strep throat test, throat culture, group A streptococcus (GAS) throat culture, rapid strep test, streptococcus pyogenes What is it used for?A strep A test is most often used to find out if a sore throat and other symptoms are being caused by strep throat or by a viral infection. Strep throat needs to be treated with antibiotics to prevent complications. Most sore throats are caused by viruses. Antibiotics don't work on viral infections. Viral sore throats usually go away on their own. Why do I need a strep A test?Your health care provider may order a strep A test if you or your child has symptoms of strep throat. These include:
Your provider may also order a strep A test if you or your child has a rough, red rash that starts on the face and spreads to another part of the body. This type of rash is a sign of scarlet fever, an illness that can happen a few days after you've been infected with strep A. Like strep throat, scarlet fever is easily treated with antibiotics. If you have symptoms such as a cough or runny nose along with your sore throat, it's more likely that you have a viral infection rather than strep throat. What happens during a strep A test?A rapid test and a throat culture are done in the same way. During the procedure:
Will I need to do anything to prepare for the test?You don't any special preparations for a rapid strep test or a throat culture. Are there any risks to the test?There is no risk to having swab tests, but they may cause slight discomfort and/or gagging. What do the results mean?If you or your child has a positive result on a rapid strep test, it means you have strep throat or another strep A infection. No further testing will be needed. If the rapid test was negative, but the provider thinks you or your child might have strep throat, he or she may order a throat culture. If you or your child has not already provided a sample, you will get another swab test. If the throat culture was positive, it means you or your child has strep throat or other strep infection. If the throat culture was negative, it means your symptoms are not being caused by strep A bacteria. Your provider will probably order more tests to help make a diagnosis. If you or your child was diagnosed with strep throat, you will need to take antibiotics. Most often you will need to take them for 10 days. After a day or two of taking the medicine, you or your child should start to feel better. Most people are no longer contagious after taking antibiotics for 24 hours. But it's important to take all the medicine as prescribed. Stopping early can lead to rheumatic fever or other serious complications. If you have questions about your results or your child's results, talk to your health care provider. Learn more about laboratory tests, reference ranges, and understanding results. Is there anything else I need to know about a strep A test?Strep A can cause other infections besides strep throat. These infections are less common than strep throat but are often more serious. They include toxic shock syndrome and necrotizing fasciitis, also known as flesh-eating bacteria. There are also other kinds of strep bacteria. These include strep B, which can cause a dangerous infection in newborns, and streptococcus pneumoniae, which causes the most common type of pneumonia. Streptococcus pneumonia bacteria can also cause infections of the ear, sinuses, and bloodstream. References
