Components of the Test:

  • Quantitative ASO antibody measurement (IU/mL)

Understanding the Test Report:

  • High ASO levels → Recent/ongoing streptococcal infection

  • Rising titers over time → Active or recent infection

  • Decreasing titers → Recovery phase
    Interpretation is based on age, symptoms, and clinical condition.

Preparation and Procedure:

  • Routine blood sample

  • No special preparation needed

How is the Test Done?
