TABLE 3.
Diagnostic sensitivity of ASO, ADB, and anti-SpnA in the triplex assaya
| Patient group | ASO | ADB | Anti-SpnA | P valueb |
|---|---|---|---|---|
| ARF <28 days (n = 72), n (%) | 63 (88) | 63 (88) | 61 (85) | 0.853 |
| ARF 28+ days (n = 25), n (%) | 23 (92) | 24 (96) | 15 (60) | 0.001 |
a
Sensitivity is defined as the number of ARF patients (n) with antibody titers above the experimentally determined ULN cutoffs. ARF patients were stratified into those with sera obtained <28 days after hospital admission and 28+ days after hospital admission.
b
The P values were determined by 3 × 2 χ2 test.
