In brief: Timing

There is a period of time during which the antibody response has not reached a level that RF would be triggered.
Studies suggest you have up to 10 days from first fever to start abx before the trouble would start.It is likely 5 days for the kidney damage sometimes associated with strep. Consider it a near miss.
