Strep Throat

 

Strep Throat Treatment in Princeton & Lawrenceville, NJ

Strep throat is a bacterial infection caused by Group A Streptococcus.

Unlike most sore throats, which are viral, strep throat requires testing and treatment with antibiotics. Prompt diagnosis reduces complications and shortens contagious spread.

If you live in Princeton, Lawrenceville, West Windsor, Plainsboro, Hopewell, Pennington, or Robbinsville, early evaluation can clarify whether your symptoms are viral or bacterial.

Quick Takeaways

• Strep throat is bacterial and requires testing

DIAGNOSIS

What We Assess in Clinic

Evaluation includes:

• Symptom onset

If rapid testing is negative in children but suspicion remains high, a throat culture may be considered.

Not every sore throat requires testing.
