Rapid Strep Test
If you are having any symptoms or have any questions, please call 811 to speak with a registered nurse 24 hours a day.
Too painful to swallow, too sick to eat — it’s a sore throat that feels worse than normal. Your first thoughts turn to strep throat. A rapid strep test in your healthcare provider’s office is a quick method of confirming your suspicions. Note: rapid strep tests may not be available at all healthcare provider’s offices or walk in clinics.
Viruses cause most sore throats. However, strep throat is an infection caused by the Group A streptococcus bacteria. The infection occurs in the throat and tonsils. The germ spreads through the tiny spray that comes from an infected person’s cough or sneeze. Once you get the germ, symptoms usually appear within two to five days. Plenty of adults get strep throat. However, it is most common in children between the ages of 5 and 15.
Path to well being
Your healthcare provider will look at the inside of your throat using a tongue depressor and flashlight. Physical signs of strep throat include redness, as well as white or yellow spots on the tonsils. If you have strep throat, you also may have swollen glands in your neck. Your healthcare provider may place their hands around your neck to feel for swelling. Your healthcare provider may check your temperature (a fever of 101 degrees or more is typical with the strep infection). They may ask you if you have experienced chills, headache, loss of appetite, nausea, a rash, or an overall feeling of illness, as these are also common symptoms.
Test confirmation: After reviewing your physical signs and symptoms of strep throat, your healthcare provider may perform a rapid strep test (also called a rapid antigen test). A rapid strep test is done in the healthcare provider’s office during your visit. It involves sampling the bacteria from the back of your throat and tonsils. The healthcare provider will insert a long, sterile cotton swab in your mouth and rub the back of your throat and tonsils to collect a bacteria sample. Swabbing is quick. However, the procedure can make you gag. If your child is being swabbed for strep throat, encourage them to relax and sit still to make the procedure go smoothly. Most people react with little more than a cough after the procedure. The sample then undergoes rapid testing in the office while you wait for the results. The wait may take 7 to 15 minutes to find out if you test positive or negative for the strep infection. If the test is negative for strep bacteria, your healthcare provider will give you tips on how to ease the pain of a sore throat. If the results are negative, but all physical signs and symptoms point to an infection, your healthcare provider may send the sample to an outside lab for additional testing. It could take a few days to get the results. If the test is positive for the strep infection, your healthcare provider will prescribe an antibiotic to kill the bacteria.
Things to consider
Strep throat will worsen if not treated or if you don’t finish all of your antibiotic medicine. Complications from untreated strep throat include kidney inflammation or rheumatic fever (an inflammatory disease that causes pain in the joints, a certain type of rash, or heart valve damage). Other things to consider include:
- You can continue to spread the infection to others during the first 24 to 48 hours of antibiotic use. Adults and children with strep throat should stay home from work, school, and daycare during that time.
- Replace your (or your child’s) toothbrush after the first few days of starting antibiotics. The infection can survive on your toothbrush and re-infect you or another family member if toothbrushes are kept together.
- If you have (or your child has) strep throat repeatedly, contact your healthcare provider. You may be a carrier. A carrier has strep in their throat but show no signs of illness. Treating the carrier can keep others in your family from getting the infection.
- A rapid strep test will not find other causes of a sore throat.
Don’t share food, drink, or utensils with someone who has the strep throat infection. That’s good advice for any type of sore throat or cold symptoms.
