Why undergoing this examination?

Immune allergic reactions are complex immune processes, which can be mediated by both immunoglobulin E (IgE) and specific immunoglobulin G (IgG) antibodies to food antigens (proteins). IgE-mediated reactions are food allergies per se, while IgG-mediated reactions are known as food hypersensitivity (popularly known as food intolerances). Many individuals suffer from chronic food intolerance to certain foods. It is estimated that approximately 20-35% of the population may present this type of reaction. The withdrawal of foods from the diet to which the individual presents specific IgG antibodies provides a significant improvement in their symptoms.

What is this exam?

The A200 test consists of the determination of serum IgG antibodies against more than 200 food proteins of the Mediterranean diet. Dietary elimination of foods with hypersensitivity (abnormal levels of IgG) provides a remarkable improvement in a high percentage of patients. Thus, the A200 is an important option to take into account any adverse clinical manifestations without diagnosis (gastrointestinal disorders, dermatological processes, respiratory changes, etc.).

For whom is it indicated?

People who present any of the following clinical symptoms without an etiological diagnosis and/or no improvement with usual medical treatments:
• Gastrointestinal disorders: abdominal pain, constipation, diarrhea, abdominal bloating, nausea, acidity, ulcers and ulcers, gastritis, colitis.
• Dermatological processes: acne, eczema, psoriasis, hives.
• Neurological diseases: headache, migraine, dizziness, vertigo.
• Respiratory disorders: cough, bronchitis, asthma, rhinitis.
• Psychological conditions: anxiety, depression, fatigue, hyperactivity.
• Musculoskeletal disorders: pain, stiffness, arthritis, fibromyalgia.
• Others: fluid retention and obesity.
