The anti-streptococcal hemolysin “O” test, also known as the anti-streptococcal hemolysin “O” test, may be elevated due to group A hemolytic streptococcal infections and non-hemolytic streptococcal infections. 1. Group A hemolytic streptococcal infections: The anti-streptococcal hemolysin “O” test is often used to assist in the diagnosis of group A hemolytic streptococcal infections. If the test is found to be high, it may be due to hemolytic streptococcal infections, tonsillitis, streptococcal pharyngitis, scarlet fever, and salmonella. 2. Non-hemolytic streptococcal infections: high results of anti-streptococcal hemolysin anti-streptococcal “O” test may also be caused by non-hemolytic streptococcal infections, such as connective tissue disease, subacute infective endocarditis, multiple myeloma, viral hepatitis, nephrotic syndrome, tuberculosis and other diseases. It is recommended that patients with high anti-streptococcal hemolysin anti-streptococcal “O” test results should go to the hospital in time to improve the relevant examinations and determine the cause of the disease, and then follow the doctor’s instructions to standardize the treatment.
