Murine models are readily used to investigate mechanisms potentially involved in anaphylaxis. Determining successful sensitization with current methods remain potentially lethal, invasive, expensive and/or cumbersome. Here we describe the use of thermography to read intradermal testing to detect peanut allergic sensitization in the murine model and as a first time sensitive tool for anaphylaxis stratification. The relative wheal size in the thermal image can be used to stratify anaphylaxis severity risk groups prior to a challenge. This screening method is nonlethal, inexpensive, minimally invasive and can be carried out expeditiously.
