3rd Generation IgE Allergy Test - FABER

The first generation of allergy test involves binding allergenic extracts to a solid phase and then incubating this with the patient’s serum, This RAST test involves dangerous radioactive materials and could only be performed in specially equipped laboratories.


The second generation tests involve measuring the degree of colour change or the strength of the fluorescence to determine the quantity of bound anti-IgE antibodies.


Recent developments in allergy blood tests include the use of molecular allergens. Since a crude allergen extract contains many different proteins, only a few of which can cause an allergic reaction, binding to the irrelevant proteins often result in false positive results, the accuracy of the tests would improve. Another recent development is the multiplex assay, the amount of allergens needed is also greatly reduced, thus lowering the cost of the test. It also allows more allergens to be tested with a given amount of blood sample.

Faber Allergy Test employs nanotechnology and is a 3rd generation multiplex assay. It can accurately measure total IgE level up to 25,000 IU/ml in blood serum.
