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.

Quick Fact TempTest®

    • The TempTest® is extremely user friendly and quick.
    • A successful therapy can be achieved and measured by monitoring the threshold temperature.
    • 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.
    • By threshold temperature determination for Cold Contact Urticaria, symptoms would be evitable as much as possible: e.g. avoiding stimulant food, drinks or specific sports by using special clothes, protective products etc..
    • Patient is able to warn other doctors of any specific temperature before starting any treatment.
    • No common unwanted side effects by this device reported. In case of positive test and wheals observation, it may remain a few minutes up to hours, along with itching/burning rarely. However, they relapse to normal condition after several hours without any trace.
