What is ASO titre negative?
A negative test result means that you do not have strep infection. Your health care provider may do the test again in 2 to 4 weeks. At times, a test that was negative the first time may be positive (meaning it finds ASO antibodies) when done again. Normal value ranges may vary slightly.
When does ASO titer positive?
The antibodies level starts to rise in 1-3 weeks after streptococcal infection, peaks in 3-5 weeks, and then goes back to insignificant level over 6-12 months, so a positive test can indicate current but more recent group A, C, and G streptococcal infection and may support the diagnosis of poststreptococcal infection …

Increased levels of ASO titre in the blood could cause damage to the heart and joints. In most cases, penicillin is used to treat patients with increased levels of ASO titre.
What is a high ASO titre?
An elevated titer of antibody (positive ASO) or an ASO titer that is rising means that it is likely that the person tested has had a recent strep infection. ASO titers that are initially high and then decline suggest that an infection has occurred and may be resolving.
What is streptococcal infection?
Streptococcal infections are any type of infection caused by the group of bacteria Streptococcus. There are many different types of Streptococci and infections vary in severity from mild throat infections to pneumonia.

What causes high ASO levels?
ASO antibodies will remain detectable in your blood for several months after an infection. If you have elevated levels of ASO antibodies, it means that you have probably had a recent strep infection. If your levels are taken again later and are higher, it also means you’ve probably had a recent strep infection.

Normal values for both the ASO titer and the ADB titer rose sharply during early childhood and then declined gradually with age. The estimated titers that were 80% of the upper limit or normal at age 10 years were 276 IU/ml for ASO and 499 IU/ml for ADB.
