Report
An allergy is a hypersensitivity disorder of the immune system that causes undesirable reactions to certain substances like food, dust, pollen, drugs or even animal dander. These reactions normally do not occur in others. The substance causing the reaction is an allergen. Immunoglobin E is an antibody that the body produces in case of an allergic reaction. A total IgE test is a blood test used to measure the complete IgE levels in the blood, but it does not indicate what is the specific allergen causing the reaction. Allergy- Dust panel is a screening that tests the body’s reaction to 4 different sources of dust including House Dust (Greer Labs), D Farinae, D Pteronsysinus, and Cockroach using the ImmunoCAP technique. Based on the results the source of allergy/allergies is determined and the course of treatment is decided accordingly. Along with this, the allergen-specific IgE levels are also checked.
The dust allergy panel test is a diagnostic tool designed to identify an individual’s allergic response to specific components commonly found in dust. This test measures the body’s immune reaction, particularly the IgE-mediated response, to four primary sources of inhalant dust allergens: House Dust (Greer Labs), Dermatophagoides farinae (D Farinae), Dermatophagoides pteronyssinus (D Pteronyssinus), and cockroach allergens. This test determines the presence and severity of dust allergies by measuring allergen-specific IgE antibodies in the blood.
This test is key in diagnosing and managing allergies caused by dust. It pinpoints the allergens causing symptoms like sneezing, runny nose, itchy eyes, coughing, and difficulty breathing. The results help healthcare professionals create targeted treatment plans. These might include allergen-specific immunotherapy (ASIT) or other medications.
Additionally, the test allows you to identify and avoid allergens, check how well you control your environment, and diagnose unusual allergic symptoms linked to dust.

Tree pollen allergy panel is done for suspected inhalant allergies due to pollen from trees to determine the exact source causing it (allergen).
Pollen allergy test measures the IgE mediated response to pollen from 4 different trees:
- Alder (Alnus incana)
- Birch (Betula verrucosa)
- Oak (Quercus alba)
- Willow (Salix capera)
Total IgE levels are also measured.
Pollen allergy test requires a blood sample post exposure to the allergens. 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.
Positive result to an allergen indicates that the person is allergic to it. Increased allergen-specific IgE levels further confirms that. Very often the test may be positive for more than one allergen as well. The further treatment course is decided based on the results. Based on the symptom, age, environmental allergens, and region wise allergens further testing may be required for specific diagnosis. Negative result may require other tests for differential diagnosis.
