Strep testing, fast diagnosis

A sore throat can be caused by a virus, by bacteria like strep, or by less common issues like mono or post-nasal drip. The treatment is very different depending on the cause. Strep needs antibiotics; viral sore throats don't (and antibiotics don't help). Guessing wrong means either antibiotic side effects you didn't need or days of unnecessary discomfort.

Our providers examine the throat, run a rapid strep test on site with results in about 5 minutes, and start treatment the same visit if needed. We also provide signed return-to-school or work notes.

When to come in

Sore Throat Treatment FAQs

You can't reliably tell by looking — even doctors can't. Strep tends to come on suddenly with fever, swollen tonsils, and no cough. Viral sore throats often come with cough, runny nose, and hoarseness. The only way to know for sure is a rapid strep test, which we do on site.

The throat swab takes a few seconds. Results are ready in about 5 minutes. If strep is confirmed, treatment starts the same visit.

Most people with strep feel significantly better within 24–48 hours of starting antibiotics. Finish the full course (usually 10 days) even after you feel better.

Once you've been on antibiotics for 24 hours and are fever-free, you're no longer contagious and can return. For viral sore throats, return when fever has resolved and you feel up to it.

Only if it's strep or another bacterial infection. Most sore throats are viral and antibiotics don't help — they can cause side effects and contribute to antibiotic resistance.

Yes. Tonsillitis, mononucleosis, post-nasal drip from allergies or sinusitis, acid reflux, and dry air all cause sore throats. We evaluate for these when strep is ruled out.

No. Walk in any day from 8 AM to 8 PM.

Yes. Most plans cover urgent care visits with a copay. We accept Aetna, BCBS, Cigna, UHC, Horizon, Medicare, NJ FamilyCare, Humana, and Oxford.

For routine sore throats, no. Go to the ER if you have trouble breathing, can't swallow your own saliva, have a stiff neck, or feel severely ill.
