Hundreds and thousands of Britons suffer from an allergic reaction or other. Allergies are recognized as one of the most common chronic health conditions that particularly affect our natural immune system. Doctors at a London clinic renowned for conducting allergy tests explain the topic further in the following lines.

Under normal circumstances, whenever bacteria, virus or any other infectious agent enters into our body, the immune system becomes active to destroy it. But when you have an allergy, your immune system considers the infectious agent as a threat and triggers an allergic reaction to countermeasure its advances. This is how you suffer from allergic reactions.

Understanding allergens

Allergen or allergens is a term used to refer to substances that trigger allergic reaction – explains a doctor associated with a renowned clinic for private blood tests in London. Numerous varieties of allergens exist in the world, including dust, pollen, types of foods and even certain medicines.

Allergens can trigger varying symptoms, ranging from insignificant ones like sneezing and stuffy nose to more serious and life-threatening ones, which are medically referred to as anaphylactic shock.

If you suffer from frequent attacks abnormalities and not sure of what are triggering them, better get your blood tested. This kind of tests is called allergy blood tests.

Allergy blood tests

Allergy blood tests are not only safe but are also highly accurate to determine if you suffer from any allergy. In order to suppress the threat from an allergen, your immune system produces antibodies, which are known as immunoglobulin E or IgE. Allergy blood tests measure the level of IgE antibodies in your blood to calculate the allergen-specific antibodies present in your system. The presence of IgE antibodies in the blood in lower levels is perfectly normal but when they’re present in higher levels it signifies you have an allergy.

The effective way to avoid an allergic reaction is by avoiding the allergens that trigger it. Allergy blood tests equip you with the necessary information so that you can seek the right treatment and enjoy a normal, healthy life.
