No. Since there is such a large overlap in symptoms between Influenza A/B, Covid-19 and Strep A, especially early in the course of the illness, Rockdoc’s Cold & Flu Rescue Kit was intentionally designed to test for all four. It is important to test early when there is symptom overlap, because the earlier you can identify which of these microbes is causing your illness, the earlier you can receive the correct treatment to reduce the severity of symptoms and shorten the duration of illness. The earlier you start treatment, the more effective the treatments are.
