Assessment of Anti-Streptolysin-O Titre in Healthy School-Age Children in Alexandria Governorate

Background: Serology of streptococcal [GAS] group-A is used for post-streptococcal disease diagnoses, such as acute rheumatic fever, and occasionally for streptococcal pharyngitis diagnoses. Streptococcal titers vary according to a number of factors, including age and population. In developing count...
