Your child wakes up with a fever, a sore throat, or a nasty cough — and you need to know what you're
dealing with right now. Is it the flu? RSV? Strep? At Fairway Children's Medical Group, we don't make you
wait for a lab report to come back in two days. A simple nasal or throat swab and 10-15 minutes is all it
takes to get a clear, accurate answer — so we can start the right treatment immediately, whether
that's antivirals for the flu, antibiotics for strep, or supportive care for RSV.
Getting it right matters — and so does getting it fast. Treating a virus with antibiotics doesn't work, and
leaving a strep infection untreated can lead to serious complications. Rapid testing takes the guesswork
completely out of it. At Fairway Children's Medical Group, we test on-site, read the results with clinical
expertise, and walk you out with a diagnosis and a treatment plan — all in one visit, all in one place.
That's the kind of care that actually makes a difference when your child is miserable and you need
answers.

We run all three tests right here in
the office. No sending samples to
an outside lab, no waiting 24-48
hours for results. You get answers
within minutes — and treatment
starts the same day.

Flu, RSV, and Strep all look similar
— but they're treated very
differently. Our rapid tests make
sure your child gets exactly what
they need, not a guess. No
unnecessary antibiotics, no missed
antiviral windows.

Whether your sick child is 6 weeks
old or 16 years old, we're equipped
to test and treat. Rapid Flu and
RSV testing for any age, Strep
testing for children 3 and up — all
under one roof at Fairway
Children’s Medical Group.
Rapid tests (Flu, RSV, Strep) Q&A
Flu and RSV are viruses that cause respiratory illness, often with overlapping symptoms like fever, cough, and congestion. Strep throat is a bacterial infection that typically causes a sore throat, fever, and sometimes a rash. They all need specific testing because:
👉 Treatment is different: The Flu may be treated with antivirals, Strep is treated with antibiotics, and RSV treatment is usually supportive (managing symptoms).
👉 Complications vary: Untreated Strep can lead to serious complications like rheumatic fever, while Flu and RSV can cause severe respiratory issues in young children. A rapid test guides the proper medical response for each specific illness.
Rapid tests are primarily focused on symptomatic patients, and there are no strict age cutoffs, but here are the general guidelines:
👉 Age Groups: Rapid Flu and RSV testing may be done on patients of any age, but often prioritize infants, young children, and those with underlying health risks. Rapid Strep testing is most common in children age 3 and older, as Strep throat is rare in children under 3.
👉 Sample Collection: Collection is quick and generally well-tolerated, though it may cause a brief tickling sensation.
- Flu and RSV: A gentle nasal swab is used.
- Strep Throat: A throat swab is used to rub the tonsils.
The entire collection process takes only a few seconds, and the results are typically available in about 10–15 minutes.
Not always. While rapid tests have very high specificity (meaning a positive result is almost certainly correct), they have varying sensitivity. This means a false-negative result is possible, especially if the sample has low levels of the virus or bacteria, or if the test is done very early or very late in the illness. If your child's rapid test is negative but your pediatrician still has a strong clinical suspicion, they may recommend further confirmation with a more sensitive test (like a molecular PCR test) or treat your child based on their symptoms. We are committed to providing the most accurate and timely diagnostics possible to guide your child's care.
Fairway Children's Medical Group offers fast, on-site rapid testing for Flu, RSV, and Strep, ensuring that your child receives an accurate diagnosis and the most appropriate treatment plan as quickly as possible.
