Lymphocyte Transformation Test (LTT) Blood Test

By Yesha KarmeliPublished Updated

The lymphocyte transformation test (LTT) shows immune reactions to toxins

Dental materials can cause allergies Metals, acrylates (plastics), but also numerous other components, for example those contained in root canal filling materials or cements, can be potential allergens. Qualitative toxic burden therefore refers here to how the body reacts to the toxins. Whether a sensitization to substances such as dental materials is present can be examined with so-called lymphocyte transformation tests (LTTs), which are carried out in specialized laboratories. Your physician or naturopathic practitioner (Heilpraktiker) will advise you on this and can initiate the necessary tests.

Which materials can be tested in the LTT?

LTT metals Gold, nickel, palladium, chromium, cobalt, molybdenum, aluminum, platinum, cadmium, mercury, copper, silver, tin, ethylmercury
LTT plastics Methyl methacrylate (MMA/PMMA), TEGDMA, BISGMA, HEMA, diurethane dimethacrylate, ethylene glycol dimethacrylate, butanediol-1,4-methacrylate, N,N-dimethyl-4-toluidine, benzoyl peroxide, hydroquinone, camphorquinone, phthalates, formaldehyde
LTT combination profile (dental check) Gold, nickel, palladium, chromium, cobalt, platinum, mercury, copper, silver, tin, methyl methacrylate (MMA/PMMA), HEMA, TEGDMA, BISGMA
LTT gold alloys Gold, silver, platinum, copper, palladium, tin, gallium, indium, iridium, rhodium, tantalum, ruthenium
LTT amalgam Amalgam components and organic mercury compounds: mercury, copper, silver, tin (amalgam), ethylmercury, phenylmercury, methylmercury
LTT root canal filling materials Raw gutta-percha, Peru balsam, eugenol, polydimethylsiloxane, silicone oil, bismuth oxide, silver, turpentine oil, colophony, triethanolamine, peanut oil, paraformaldehyde, bisphenol A, epichlorohydrin
LTT ceramics + cements Vanadium, aluminum, titanium, cobalt, chromium, barium, silicon, cerium, boron, manganese, antimony, phosphate cement (Harvard), glass ionomer cement (Ketac-Bond)
LTT native material Testing for selectively chosen materials, which can also be sent to the laboratory.

The lymphocyte transformation test for Borrelia (LTT Borrelia)

The diagnosis (laboratory test with blood test) of Lyme disease in the early stage should be based mainly on clinical criteria. Antibodies are only detectable up to eight weeks after infection. It should be noted, however, that a considerable number of clinically symptomatic cases at all stages cannot be clearly assessed serologically, which is another reason why clinical diagnosis is of the greatest importance.

Indications for the LTT Borrelia

  • Clinical suspicion of Lyme disease with questionable serological findings
  • Suspicion of persistent Lyme disease after previous antibiotic treatment
  • Therapy monitoring after antibiotic treatment
  • Clinical suspicion of reactivation of a Borrelia infection
