What to Do for Acute Tonsillitis When the Rapid Strep Test Is Negative or the Centor Score Is Low
When acute tonsillitis presents with one or no Centor criterion, or a negative rapid antigen detection test (Strep A), the clinical picture does not support a streptococcal aetiology. Clinical practice guidelines and expert consensus converge on a specific evidence-based approach for this scenario.
Clinical scenario: Acute tonsillitis with one or no Centor criterion, or a negative rapid antigen detection test (Strep A). Expert recommendations and clinical practice guidelines agree that no further test or antibiotic is necessary in this presentation.
Treatment approach
Management centres on symptomatic relief, combining supportive measures with analgesic and anti-inflammatory therapy. The complete structured regimen — including agent selection and the evidence behind each choice — is available in the full protocol.
