0.12s-0.20s

Normal PR Interval

5,000-10,000

Normal WBC

Elevated WBC

indicates infection

Leukocytosis

more than 10,000 WBC

positive ASO titer

Confirms prior exposure to GABHS

Laboratory Findings

These are commonly our minor symptoms

Penicillin

Medication to eliminate GABHS bacteria

Ibuprofen

Medication reduces inflammation and joint pain (arthritis)

Corticosterioids

Medication reduces inflammation; for carditis
