Allergy Genetic Testing

Allergy genetic testing is an essential medical examination that analyzes an individual's genome to assess their risk of allergic reactions. This test focuses on identifying genetic variations related to allergies, thereby helping to determine a person's sensitivity to specific allergens. The primary advantage of this test is that it can provide patients with more personalized medical advice, including preventive measures and treatment options.

Gene Tested

HLA, ADAM33, ORMDL3,  IL-4 and IL-13,  and FCER 

The essence of allergy gene testing lies in identifying key genes that affect the individual's immune system response. These genes include, but are not limited to, HLA, ADAM33, and ORMDL3, which play a crucial role in the normal function of the immune system and are associated with an increased risk of allergic diseases. For example, the HLA gene is related to an increased risk of diseases such as allergic rhinitis and asthma. Additionally, IL-4 and IL-13 are two proteins that regulate immune responses, and genetic variations in these proteins may lead to the development of allergic symptoms like allergic rhinitis, eczema, and asthma.

Moreover, the FCER1 gene is also a focus of allergy gene testing. This gene is responsible for encoding the α subunit of the immunoglobulin E (IgE) receptor, a crucial immunoglobulin closely related to allergic reactions. Variations in the FCER1 gene may increase an individual's sensitivity to allergens.
