Allergy

Three routes by which allergens normally enter in our body are:

1. Skin
2. Mouth
3. Nose

The two tests generally used to diagnose allergy are:

1. Skin prick test.
2. Blood testing

Blood testing — A sample of patient's blood is sent to a laboratory for analysis. Multiple allergens can be detected with a single blood sample. The test measures the concentration of specific antibodies in the blood. The quantitative allergy blood result can help determine what a patient is allergic to, help predict and follow the disease development, estimate the risk of a severe reaction, and explain cross-reactivity.

Histamine

Reason — The body produces Histamine in response to allergens, which leads to allergic symptoms like inflammation, skin rash and constriction of the bronchioles (as in asthma).

Immunoglobulins

Reason — In an attempt to protect our body from these allergens, our immune system produces immunoglobulin proteins that are specific to the allergen.

Anaemia

Reason — Anaemia is a condition where the body does not have enough red blood cells. It is not triggered by the body's immune system's response to an allergen.

Anaphylaxis

Reason — A systemic allergic response is termed as Anaphylaxis.

Ears

Reason — Allergens usually enter our body through skin, nose and mouth, but not through ears.

Allergy is defined as a number of conditions caused by hypersensitivity of one's immune system to allergens like dust, spores, pollen, insect stings, certain types of food and cloth, etc.

The substances that cause allergies are called allergens. Three common allergens are:

1. Dust
2. Spores
3. Insect sting

Blood test is mostly favoured for testing allergy. An allergy blood test is quick and simple, and can be ordered by a licensed health care provider. Unlike skin-prick testing, a blood test can be performed irrespective of age, skin condition, medication, symptom, disease activity, and pregnancy. Thus, we can say that blood test is a better test as compared to prick test.
