LTT 56 – Food Allergy Test

LTT is a scientifically accepted and approved laboratory test, which is applied in diagnosis of Type IV Allergy (Hypersensitivity) to food, metals and various allergens. 

Developed by Prof. Rüdiger von Baehr at SYNEVO-IMD Berlin Private Immunology Laboratory (Labor für Spezielle Immunologie), this method has been widely applied in diagnosis of Type IV Allergy in Germany since 2000.    

For LTT, blood sample is taken from patients to special tubes 

Samples are taken until 12 p.m. on Mondays, Tuesdays, Wednesdays and Thursdays on an empty stomach. The results are prepared in about 2 weeks.  

At the laboratory, the immunity cells (T lymphocytes) in blood are divided and micro cultures are reproduced under proper circumstances and put in contact with specific antigens (suspicious foods, metals and etc.). If there are any lymphocytes sensitized to allergens previously, the lymphocyte proliferation increases. The proliferation of specific T lymphocytes is observed by integrating radioactive Thimidine (3H-Thimidine) into the DNA of divided lymphocytes.

It is observed that food allergies frequency has increased 50% in society. 

This worrying situation is due to genetically modified foods, food additives, dyes, toxins, chemicals and metals. Particularly, when these factors come together with allergic genetic susceptibility and stress, a hyper response – sensitivity of the immunity system develops to foods. 

Another important function of bowels besides digestion and absorption of foods is the defense system. About 70% of immunity cells protecting the body exist in the bowels. 

Moreover, the bowels surface is covered by a protective layer comprising of constructive bacteria called biofilms. When food is digested, useful nutrients, vitamins and minerals are absorbed from the bowels, foreign matters, toxins and microbes are removed and destroyed by the intestinal barrier and immunity cells. However, if exposure to allergens continues, the resistance of the intestinal barrier and immunity cells is broken, the bowels become hyperpermeable and the response of the immunity cells is broken. In this situation called ‘hyperpermeable bowel syndrome’, the immunity cells become hyper reactive – sensitive to many foods to which they used to tolerate previously and also loses its function to block entry of foreign matters to the body. Inflammation (inflammatory reaction of the immunity system) develops in the bowels, influences on the full body and autoimmune diseases, rheumatic diseases start to develop in time.  

 At the present time, one out of every five persons complains about food allergy. 

In Germany, about 17% of women and 8% of men have Type-IV Allergy to nickel. Both skin contact to jewels and allergic reaction to nickel contained in nutrients, which is absorbed through bowels, are observed.

It has been detected that in approximately 30% of affected patients, nickel is taken through foods. Chocolate, nuts, processed meats, fruit peels, some vegetable types, seashells and dishware we use in kitchen are deemed the reasons for the nickel allergy.

Research shows an increase in the symptoms of chronic inflammation diseases such as skin reactions, eczema, rash, rheumatism, autoimmune diseases and chronic fatigue syndrome in society and nickel is among the factors that are hold responsible for.      

Therefore, nickel is included in the LTT 56 food allergy test.
