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.
What does a high ASO titer mean?
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.
How high is ASO in rheumatic fever?
A significant elevation in ASO titre was also observed in RF (202.48±128.17 IU; P=0.09) than RHD (151.30±91.01). However, similar median value (195 IU) was observed due to a wide range of variation in serum ASO titre in pharyngitis as well as in RF which was suggestive of current and/or recurrent stages of infection.
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 …
How do you reduce ASO?
Corticosteroids and certain antibiotics may reduce ASO antibody levels.
How do you cure ASO?
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 the normal range of ASO?
Generally, an ASO test value below 200 is considered normal. In children under the age of 5, the test value should be less than 100. Results will vary by laboratory. If your results show that you have an elevated ASO value, you may have a post-streptococcal complication.
