   Before the visit

   Prep

   • From Genova's provider guide: [F1]
   • Eat a variety of foods for 2 to 3 weeks before testing (except foods known to cause severe reactions). Antibodies to a food may be absent if you have not eaten it recently.
   • These medications may influence results: glucocorticoids, chemotherapy, other immunosuppressive agents, NSAIDs, anticonvulsants, omalizumab, and heparin. Do not stop any medication without your provider.
   • Freeze the freezer brick overnight.
   • Fasting: Genova does not list a fasting requirement. Follow the instructions in your kit.
