What's this test for?

This test is ideal if you're experiencing a sore throat, painful swallowing, fever, or swollen glands in your neck. It checks for Group A Streptococcus bacteria, the germ behind most cases of strep throat. Knowing whether strep is the cause helps you get the right treatment quickly and avoid complications.

What's included in this test?

This test looks for Group A Streptococcus antigen, the specific marker that shows this bacteria is present in your throat. Detecting this antigen directly is what allows for a fast, accurate answer about whether strep is causing your symptoms, rather than a virus or something else.

What happens after I get my results?

Your results will be available in your account, with a clear explanation of what a positive or negative result means. If your result is positive, next steps typically include starting treatment promptly to feel better faster and prevent the infection from spreading or leading to complications. A standard lab report is available to download from your account at any time. You can also use the trends feature to track results if you're tested more than once.

How can I naturally support my throat while recovering?
Gargling with warm salt water, staying well hydrated, and resting your voice can ease throat pain and swelling. Warm liquids like tea with honey, and soft, non-irritating foods can also make swallowing more comfortable. A humidifier at night can help keep your throat from drying out further.
When will I get my results?
Results are typically ready within about 7 days of your lab visit. You'll receive a notification and can log into your account to view the detailed report as soon as it's available.
Who should consider this test?
Anyone with a sore throat that comes on suddenly, along with fever, red or swollen tonsils, or tender neck glands, should consider this test. It's especially useful if you've been around someone recently diagnosed with strep throat. Adults who get frequent throat infections may also want to test to confirm the cause each time.
What symptoms indicate I may need this test?
Common signs include a sudden sore throat, pain when swallowing, fever, red and swollen tonsils sometimes with white patches, and tender or swollen lymph nodes in the neck. Headache and stomach upset can also occur, especially without a cough or runny nose, which is more typical of viral infections. If you notice these symptoms, testing can clarify whether bacteria are the cause.
What does a positive result mean?
A positive result means Group A Streptococcus bacteria were detected in your throat, confirming a bacterial infection. This usually calls for prompt treatment to reduce symptoms faster and lower the risk of complications like abscesses or kidney inflammation. It also means you're contagious, so taking steps to avoid spreading it to others is important.
What causes a Group A Strep infection?
Group A Strep spreads through respiratory droplets from coughing, sneezing, or close contact with an infected person, or by touching contaminated surfaces and then your face. It's especially common in school-age children but easily spreads to adults in households or close-contact settings. Crowded environments and weakened immune defenses can increase your risk of catching it.
What should I do if my results are positive?
If you test positive, focus on rest, hydration, and soothing remedies while starting appropriate treatment to clear the infection. Avoid close contact with others until you're no longer contagious, and disinfect shared items like utensils and toothbrushes. Seek medical care promptly if you develop difficulty breathing, severe throat swelling, or a high fever that doesn't improve, as these can signal a more serious complication.

What this means

A negative result means no Group A Streptococcus antigen was detected, so your sore throat is likely caused by something other than strep, like a virus. If symptoms persist or worsen, further testing may be needed to identify the cause.

* Regular blood test results (e.g., CBC) typically start arriving the next business day after sample collection. More advanced tests may take longer due to complexity.
