The Antistreptolysin O (ASO) Titre Test is a blood test used to detect antibodies produced by the body in response to an infection caused by Group A Streptococcus bacteria. It helps diagnose recent or past streptococcal infections, which can lead to complications such as rheumatic fever or post-streptococcal glomerulonephritis (kidney disease).
Why is the ASO Titre Test Done?
Doctors recommend this test to:
- Confirm a recent streptococcal infection, especially if symptoms of complications appear.
- Diagnose rheumatic fever, which can affect the heart, joints, and nervous system.
- Identify post-streptococcal kidney disease (glomerulonephritis).
- Help monitor ongoing streptococcal-related conditions.
Test Procedure and Preparation
- A blood sample is taken from a vein in the arm.
- No special preparation (such as fasting) is required.
- Results are typically available within a few days.
