What is Antistreptolysin O, ASO Titer ?
The ASO (Antistreptolysin O) Titer test is a blood test used to detect antibodies produced by the immune system in response to an infection caused by Streptococcus bacteria, specifically Group A Streptococcus. These bacteria produce a toxin called streptolysin O, and the body generates ASO antibodies to neutralize it. Measuring the concentration of these antibodies helps in diagnosing a recent or past streptococcal infection. A higher-than-normal ASO titer indicates a recent infection, which is important in identifying complications like rheumatic fever or post-streptococcal glomerulonephritis, conditions that can develop after untreated or poorly treated strep throat or scarlet fever. The ASO Titer test is commonly ordered when a patient shows symptoms that may be linked to a previous streptococcal infection, such as joint pain, swelling, fever, or kidney-related issues. It is particularly useful in diagnosing conditions like rheumatic fever, which can affect the heart, joints, and nervous system, or in cases where there is suspicion of a strep-related complication. By providing insight into past infections, the ASO titer test helps clinicians guide appropriate treatment and monitor recovery.
