TempTest®

Unique system for cold contact urticaria determination and finding the trigger temperature

Cold contact urticaria is known as a type of physical urticaria (Wheals), in which red allergic skin lesions and itching are produced by exposure to heat or cold.

TempTest® is to be used to evaluate and determine patient’s allergy to cold contact urticaria and as well is capable to determine the threshold of temperature for this symptoms.  

TempTest® provides temperatures of 4°- 44° C and transfers to the patient’s skin by placing the inner forearm on an U shape aluminum stencil on the device for 5 minutes. The U-stencil indicates the temperature range continuously. By this method it is possible easily to specify and asset at which threshold temperature (Cold urticaria is indicated by  highest temperature and heat urticaria by lowest temperature) wheals are triggered.  

As well, TempTest® is able to find and determine heat contact urticaria (In general, the wheals and skin redness occur only where the skin has come into contact with a heat source (Critical temperature varies between 38 °C to 50 °C). This is very rare and the cause is unknown. Cold contact urticaria however is the more frequent type.
