Inflammatory Markers
The following inflammatory markers are often elevated:
- CBC: Leukocytosis
- C-reactive protein
- Erythrocyte sedimentation rate (ESR)
Diagnosis of Streptococcus Pharyngitis
- Throat culture for group A beta hemolytic streptococci may be performed. However many patients may have negative culture by the time rheumatic fever develops[1].
- Rapid streptococcal antigen test is quicker. However, it has a lower sensitivity (70%) and statistically equal specificity (98%) as throat culture[2]. Therefore, negative test results rules out streptococcal infection.
- Elevated or rising antistreptolysin O antibody titer.
