Introduction to allergy blood test

 

An allergy blood test is a medical test used to measure the level of specific antibodies (IgE) in your blood that your immune system produces in response to allergens. These allergens can be things like pollen, dust mites, mold, pet dander, or certain foods. The test helps identify what substances might be causing allergic reactions in your body.

How It Works:

1. Blood Sample Collection: A healthcare professional will take a small sample of your blood, usually from a vein in your arm.
2. Laboratory Testing: The sample is sent to a lab where it is tested for the presence of IgE antibodies specific to various allergens.
3. Results: The test results will indicate whether you have elevated IgE levels for certain allergens, suggesting a potential allergic reaction.

 

Importance of allergy blood test

 

Allergic blood tests are important for several reasons, especially in the diagnosis and handling of allergic reactions. Here it is important:

 

1. The accurate diagnosis of allergies

Allergic blood tests can help identify specific allergies that trigger reactions, whether related to food, pollen, dust, mildew, pets or other environmental factors. This helps doctors confirm the cause of symptoms such as sneezing, itching, urticaria or asthma.

2. Helps with symptom management

By identifying specific allergies, the test allows individuals to avoid or reduce contact with these triggers. This is an important step in handling allergies and prevents unpleasant or dangerous reactions.

3. When the skin test is not possible, it is used

In some cases, skin tests may not be suitable due to skin conditions (eg eczema) or drug use (such as antihistamine). Allergic blood tests provide an alternative under these conditions.
