Stratification of peanut allergic murine model into anaphylaxis severity risk groups using thermography

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.
