IgG food reaction testing has been a useful test in our practice for many moons. The immune inflammatory cascade triggered by an antibody based reaction to foods can impact a variety of tissues and system well beyond the GI: chronic soft tissue pain, mood disorders, skin outbreaks, chronic rhinitis, fatigue and poor immune resistance just to name a few. Up until recently there have been some logistical barriers to complete the test, namely the need to get a regular blood draw. Genova had recently expanded their offerings to include a home blood spot option for the routine 70 antigen food IgG panel. It only requires a finger prick and collection of blood spot onto a paper blot that is mailed directly to the lab.
