Allergy Blood Test. Blood & Skin Allergy Testing In Children and Adults To Discover The Root Cause.
Environmental and food allergy testing using a sample of blood is called allergen-specific IgE antibody test (a.k.a. allergy screen). It's to help diagnose an allergy to a substance for a person who might be exhibiting allergy symptoms.
Some people can have an allergic reaction or intolerance to food and/or the environment which causes unwanted reactions. Symptoms happen because your body reacts to the allergens as an invader. Chemicals are released into your system and they manifest themselves as allergic reactions.
Food and allergy testing can determine the cause. Allergy symptoms vary from person to person and can display themselves in a variety of ways.
These symptoms can manifest themselves within a few minutes (most of the time) to a few hours after coming into contact with the allergen.
Some of the most common symptoms are:
In severe cases the victim can get Anaphylaxis shock which is very dangerous.
A scratch test (skin prick test) carefully exposes the patient to different substances. Allergy testing in children using these methods can useful but skin conditions such as eczema can certain medications can alter the outcome.
An allergy skin test is not without its risks for potential severe reactions up to and including life-threatening anaphylaxis. If you have known severe reactions to certain food or allergens, an alternative can be an allergen-specific IgE antibody test.
This is normally a rast test (radioallergosorbent test) and has a minimal effect on the patient.
An blood test is not perfect and can be dependent upon the physician’s interpretation. The IgE test may come back positive but the person may not have a real physical allergy or may never have experienced an allergic reaction.
A negative result may indicate the you might not have a real true allergy. It's a good rule to listen to your body and know the possible symptoms even if your blood test results say something else.
If you think you have an allergy, an intolerance or other symptoms of food and/or environmental allergies, it's best to talk to your doctor or allergist. Another avenue is a chiropractor who practices Applied Kinesiology or muscle testing.
These kinds of food allergy symptoms can be potentially life threatening due to Anaphylactic shock so it's best to get professional help. The doctor, allergist, or chiropractor can perform different types of allergy tests, including an allergy blood test, to determine the root cause of the allergy and treat it accordingly.
