Rheumatic fever can occur 2-4 weeks after the initial event of strep throat.
The test to consider would be blood tests, such as the the antibody antistreptolysin O. Other antistreptococcal antibodies can be considered, such as anti-DNAse B, anti-DNAse, and antihyaluronidase, if the initial tests are negative.
Accompanying symptoms such as arthritis or involuntary movements can be associated with rheumatic fever.
These options can be discussed with your personal physician.
Followup with your personal physician is essential.
