TempTest®

Device to determine cold contact urticaria and the individual threshold temperature for the patient

TempTest® produces temperatures of 4°- 44° C. which are applied to the skin. The patient places the inner forearm on an aluminum stencil on the device for 5 minutes. The stencil shows the temperature range continuously. With this procedure it is determined at which threshold temperature (highest temperature for cold- and lowest temperature for heat urticaria) wheals are triggered.
TempTest® determines if a patient suffers from cold contact urticaria (CCU) and at what threshold temperature the symptoms occur. Cold contact urticaria is a form of physical urticaria, in which with contact of the skin with temperatures below skin temperature, symptoms like itching, burning wheals and/or angioedema will occur.
TempTest® can also detect heat contact urticaria (reaction to contact with temperatures above skin temperature). Cold contact urticaria however is the more frequent type.

Quick Fact TempTest®

    • The TempTest® is extremely easy and quick to handle.
    • Only by permanently checking the threshold temperature, the success of a therapy becomes measurable.
    • The comfortable measurement at the inner forearm helps the patient to understand the diagnosis and the treatment success.
    • The device can be used on adult and pediatric patients.
    • Once the patient knows the individual threshold temperature for the CCU, symptoms can be avoided as far as possible: e.g. by avoiding special food, drinks or specific sports, by wearing protective clothes whenever it is below the threshold temperature, by using skin protection products and many more precautions.
    • Other doctors can be informed of the critical temperature before any possible treatment to minimize risks.
    • Unwanted side effects are very uncommon. If the test is positive and wheals form, they may last some minutes up to hours, including in some cases itching and/or burning. However, they regress after several hours without lasting consequences.
