Introduction
Modified Centor Scoring system
| Criteria | Points |
|---|---|
| temperature > 38C | 1 |
| absence of cough | 1 |
| swollen, tender anterior cervical nodes | 1 |
| tonsilar swelling or exudate | 1 |
| age 3-14 years | 1 |
| age 15-44 years | 0 |
| age > 45 years | -1 |
A score of 2 or less makes Streptococcal pharyngitis unlikely & no testing or empiric antibodies indicated
A score of 3 or higher warrants a rapid antigen detection test
A score of 4 or higher formerly warranted empiric antibiotic therapy, but not in MKSAP19[3]
A positive rapid antigen test should warrant antibiotic therapy & a confirmatory throat culture
