Test LTT-MELISSA

MELISA is a blood test derived from the “lymphocyte transformation test”, designed to diagnose delayed (Type IV) hypersensitivity to metal components (primarily mercury, palladium, and lead salts), chemical substances (such as formaldehyde), and other low-molecular-weight allergens, including medications and certain bacteria (such as Candida albicans)

Please note: MELISA not measure the levels of metals (heavy/toxic metals) in patients’ bodies; rather, it determines whether the patient has a hypersensitivity to these substances. The level of reactivity is measured using a Stimulation Index (SI). Each substance tested is assessed at two different concentrations. A value above 3 is considered positive. For screening for ten metals, 36 mL of blood is required. Results are obtained in approximately ten days.

EACim Partner Laboratories for LTT-MELISSA Testing

Tests routinely performed

  1. Methylmercury / Inorganic mercury / Thimerosal (ethylmercury = vaccines)

  2. Flours (cereals) / Gluten

  3. Casein / Cow’s milk

  4. Candida (sugar intolerance) / Baker’s yeast

  5. Nickel (contact dermatitis, stainless steel cookware)

  6. Glutamate (E621)

A number of theories link these hypersensitivity phenomena to chronic conditions, such as eczema and psoriasis (in the field of dermatology), chronic fatigue syndrome, autoimmune diseases (thyroid disorders and Sjögren’s syndrome), and neurodegenerative disorders (multiple sclerosis, ALS, and Alzheimer’s disease).

In some cases, patients experience an improvement in their health after eliminating the sources of allergens.

However, we have major reservations:

  • These tests are very expensive, although they are reimbursed in some countries (e.g., Switzerland).

  • These tests are extremely specific (perhaps too specific?); for example, a patient may have an intolerance to certain mercury salts but not to others.

  • Organic cofactors (regulatory factors) are not taken into account, which may explain the high number of failures, even after careful elimination of the identified irritant.

  • It is often impossible to act upon the identified irritant; in some cases, complete tooth extraction has even been proposed
