An anti-streptococcal hemolysin of 700 indicates the presence of a streptococcal infection, which may have symptoms such as fever and cough, and may even affect the joints and the heart, and is often more serious. Antistreptococcal hemolysin above 500 is clinically significant (400 in rheumatoid diseases, depending on geographic location) and indicates the presence of a streptococcal infection, which can cause symptoms such as sore throat and fever. Streptococcal infections may also lead to rheumatoid arthritis and, when the heart muscle is involved, to rheumatic heart disease. In addition to streptococcal infections that can cause elevated anti-streptococcal hemolysin, other non-streptococcal infections can also cause elevated anti-streptococcal hemolysin, such as viral hepatitis, lupus erythematosus, and other diseases. To summarize, it is recommended to consult a doctor in time, combined with other relevant examinations and symptoms, to make a clear diagnosis, and then carry out targeted treatment.
