1. Can an anti-DNase B or an ASO be used to diagnose strep throat?
No, because Anti-DNase B and ASO are not detectable when a person first becomes infected. A throat culture or a rapid strep test is the best method to diagnose streptococcal pharyngitis. It is important that strep throat be promptly identified and treated to avoid complications and to avoid passing the infection on to others.
2. Can I develop rheumatic fever or glomerulonephritis at the same time as my strep throat?
These complications develop after the initial strep infection resolves. There is a delay when signs and symptoms of these sequelae appear after the streptococcal infection, about 1-2 weeks for glomerulonephritis and about 2-3 weeks for rheumatic fever.
3. If I am diagnosed with strep, will an anti-DNase B or ASO always be performed?
No. In general, these tests are only performed when someone has symptoms suggesting that a complication may have developed after a group A strep infection that was not diagnosed and treated appropriately. Most people do not experience these complications, so these tests are not routinely done.
