It depends on your goal. If you want to know what’s happening in your gut microbiome, to get a « snapshot » of it and moreover, to understand how you can improve it or be more aware of the different factors that can cause more or less gastrointestinal or extra-intestinal symptoms, you should wait 5 to 6 months before using the test so that your microbiome more closely resembles what it was before antibiotic therapy.
