Anti-Streptolysin O (ASO) Titer Report Format — Sample & Free Download
An Anti-Streptolysin O (ASO) Titer measures antibodies produced against streptolysin O, a toxin released by group A Streptococcus bacteria. Rising or elevated titres support a recent streptococcal infection and help investigate its post-infectious complications.

When is it ordered?
- Investigating suspected rheumatic fever after a sore throat or scarlet fever episode
- Evaluating post-streptococcal glomerulonephritis or joint symptoms following a strep infection
- Confirming recent group A Streptococcus exposure when a throat culture wasn't done or was negative
- Follow-up testing with a repeat titre 2-3 weeks later to check for a rising trend
Test details
- Specimen type
- Serum
- Turnaround time
- Same day (6 hours)
Anti-Streptolysin O (ASO) Titer report format breakdown
| Parameter | Unit | Normal range | What it means |
|---|---|---|---|
| ASO Titer | IU/mL | 0 - 200 | Elevated titres suggest recent or past infection with group A Streptococcus and support conditions like rheumatic fever or post-streptococcal glomerulonephritis; a single result is interpreted alongside symptoms and, ideally, a repeat titre. |
Frequently asked questions
What does an ASO Titer report format show?
The report lists a single ASO Titer result with unit, reference range, and status — as shown in the sample report above.
Do I need to fast before an ASO Titer test?
No fasting or special preparation is needed for an ASO Titer test.
What does a high ASO titre mean?
A high or rising ASO titre supports a recent streptococcal infection and is used mainly to investigate suspected rheumatic fever or post-streptococcal kidney inflammation, alongside symptoms and clinical history.
Why might my doctor repeat the ASO test?
A single titre reflects a point in time, so doctors often repeat the test 2-3 weeks later to check whether the titre is rising, which is more meaningful than one isolated result.
