[Antistreptolysin--O titers in normal persons]
Mikrobiyoloji Bulteni
|January 1, 1983
Summary
This study determined antistreptolysin O (ASO) titers in 120 healthy individuals across various age groups. The average ASO titer was found to be 160.37 +/- 14.08 Todd units, with fewer than 20% exceeding 200 units.
Area of Science:
- Immunology
- Clinical Chemistry
Context:
- Establishing reference ranges for serological markers is crucial for accurate disease diagnosis.
- Antistreptolysin O (ASO) titers are important indicators of recent streptococcal infections.
Purpose:
- To determine the normal range of Antistreptolysin O (ASO) titers in a healthy population.
- To establish age-specific reference values for ASO titers.
Summary:
- ASO titers were measured in 120 healthy individuals from diverse age demographics.
- The mean ASO titer was calculated as 160.37 +/- 14.08 Todd units.
- Less than 20% of the normal cohort exhibited ASO titers exceeding 200 units.
Impact:
- Provides essential reference data for interpreting ASO test results in clinical practice.
- Aids in differentiating between normal antibody levels and those indicative of active or recent streptococcal infection.
- Contributes to the understanding of immune responses to streptococcal antigens across different age groups.
