Allergy component testing (CRD)

This is an AI based test to detect the antibodies against 158 food allergens, 127 respiratory allergens and 10 contact allergens.

• This test helps in improved diagnosis of patients suffering from IgE-mediated diseases and selection of patients for allergen Immunotherapy.
• The test also helps in the prognosis and understanding of cross-reactivity
•  To Differentiate between primary allergen sensitisation and reaction to cross-reacting components
• It can also help establish patient’s allergy to component of different food items allowing rest of the food to be consumed and in some cases allow consumption of allergic component after heat treatment (food component specific).

• Patients with suspected allergies showing common symptoms like itching, running nose, sneezing, coughing, diarrhoea, hives
• Those with suspected parasitic or fungal infections.
• Certain autoimmune disorders.

This test requires a blood sample. A tourniquet (elastic) band is placed tightly on the upper arm. The patient is then asked to make a fist. This helps in the build-up of blood filling the veins. The skin is disinfected before needle insertion and the blood sample is collected in vacutainer.

No special precautions.

Presence of antibodies to specific IgE may indicate allergy positivity as well as cross reactivity to certain allergens.
