Disease staging: CliniCal anD CoDeD Criteria - HCUP

Antistreptolysin-O titer (ASO Titer):
Antibody titer for Group A
β-hemolytic Streptococci. Titer rises in 1 week, peaks at 3 - 5 weeks and returns to
baseline in 6 months to 1 year. [serology report]
Increased: > 166 Todd Units
Reference range: ≤ 166 Todd Units
α 1 -Antitrypsin:
Decreased:
Newborn ≤ 114 mg/dL [chemistry report]
Adult ≤ 48 mg/dL [chemistry report]
> 60 y ≤ 94 mg/dL [chemistry report]
Reference Ranges: Newborn 145 - 270 mg/dL
Adult (M-phenotype) 78-200 mg/dL
> 60 y 115 - 200 mg/dL

OR ventricular premature contraction [ECG Report]
OR junctional premature contraction [ECG Report]
OR atrial fibrillation [ECG Report]
OR supraventricular tachycardia [ECG Report]
OR atrial flutter [ECG Report]
