HOB Food Intolerance Screening ELISA Test - The “Nutrition Consultant”

The incidence of food intolerance in the general population is as high as 50%, resulted from high serum food-specific IgG levels. This leads to many chronic diseases such as eczema, urticaria, anaphylactoid purpura, lichenoid amyloidosis, acne, and so on. Due to the wide spectrum of clinical symptoms, it is in general difficult to diagnose. Patients are not usually aware of food intolerance and its consequences, and continue to consume the foods that exacerbates the underlying pathology and outward symptoms. A timely change of diet is now possible thanks to this food intolerance screening test, finally relieving patients from long-term suffering. HOB Food Intolerance Screening ELISA Test measures the food-specific IgG antibodies in human serum, providing a comprehensive overview of human body’s immunological response to up to 100 different types of food and/or ingredients. Quality of life can be greatly improved by making dietary changes based off of these screening results.

Intended Use

* For patients suffering from chronic symptoms such as chronic urticaria, eczema, erythema, lichenoid amyloidosis, anaphylactoid purpura, psoriasis, acne, long-term abdominal pain, chronic diarrhea, anabrosis, ozostomia, nausea, flatulence, irritable bowel syndrome, migraine, chronic cough, asthma, allergic rhinitis and so on;
* For people who have food preference;
* For people with suboptimal health status.
Multiple Panels
Test Principle
1. Specific allergens are immobilized into individual microplate wells.
2. The allergens are allowed to react with specific antibodies present in the patient’s serum.
3. Excess serum proteins are removed by the washing step.
4. Enzyme labeled antibody conjugate is allowed to react with the allergen-antibody complex.
5. A color is developed by the addition of a substrate that reacts with the coupled enzyme.
6. The color intensity is measured by photometer and is proportional to the concentration of IgG antibody specific to a particular allergen.
Testing Procedure
Features and Benefits
Simple: 2 mL of whole blood is drawn from patients for testing. Fasting or dietary change is not needed.
Comprehensive: Multiple and customizable panels are available.
Easy: The testing procedure can be performed either manually or automatically.
Fast: Software enables automated result interpretation and reporting in 2 hours.
Reliable: The semi-quantitative determination is highly sensitive and specific.
Safe: Post screening, dietary modification is recommended with no drug intervention.
Results Interpretation
The result, per serum food specific IgG antibody concentration (U/ml),
is categorized into four classes as shown in below table.
