About This Test
The ASO blood test detects antibodies to Streptococcus pyogenes and helps confirm recent or past streptococcal infection, particularly in cases of rheumatic fever or post-streptococcal glomerulonephritis.
The ASO test measures the level of antibodies (antistreptolysin-O) produced by the body in response to infection with Group A β-hemolytic Streptococcus (Streptococcus pyogenes). These bacteria produce streptolysin-O, a toxin that damages red blood cells and tissues. When the body is infected, it develops ASO antibodies to neutralize this toxin.
Elevated ASO levels therefore indicate recent or past streptococcal infection.
• Elevated values of ASO are consistent with an antecedent infection by group A streptococci.
• Infections by the group A streptococci are unique because they can be followed after a period of latency by serious complications such as rheumatic fever and glomerulonephritis.

TAT Policy
The Turnaround Time (TAT) depends on the following factors:
- Registration date and time
- Type of scan or test
- Scan time or sample collection time
In uncommon circumstances, TAT may be delayed due to test complexity or reasons beyond our control. You will be informed of the estimated TAT at the time of registration.
