Spotting the Culprit: Food Allergy Blood Test

A simple food allergy can change the way a person live his or her life for it basically makes this person a little altered than his or her allergy-free contemporaries. Allergies with certain types of food are caused by a specific chemical that is a common chemical ingredient in that same food. So, it is not surprising that an allergy to food may also cause a reaction to medications which subsequently leads to an alteration in medications, too.

As a result, medical professionals have been finding ways to detect food allergies as early as possible before the reactions take place. There are numerous testing processes that they utilize in finding out whether a patient is allergic to certain types of chemicals. One of these tests includes blood testing.

But before going further about blood testing, you should first understand what goes on inside the body during the allergic process.

There are two ways that the immune system reacts to an allergy. One approach is that the body, after the detection of allergens, generates immunoglobulin E or IgE which is a kind of antibody. IgE is then disseminated in the blood stream. The other approach is the occurrence of mast cells. Mast cells appear in the body tissues particularly in common allergy sites like the throat, nasal cavity, oral cavity, skin, lungs, and the organs of the gastrointestinal system.

There are cases that the capacity to produce immunoglobulin E to fight off a certain food allergen is in inherited. Individuals who are at higher risk in being afflicted with food allergies are those who have blood relations who have suffered from asthma, eczema, and hay fever.

Furthermore, an individual must initially be in contact with the potential food allergen before his or her body produces the antibody IgE. As the individual is finally exposed to the allergen the IgE is then produced and consequently fastens itself to the mast cells. This team up will eventually cause body chemical reactions the next time the allergen is eaten by the hapless individual.

Now, this immunoglobulin E is important in the detection for allergies through blood testing. The most frequently utilized blood tests are Radioallergosorbent test (RAST) and CAP-RAST (which is basically similar to RAST but more advanced).

In blood tests, the outcome is ranked from one to six, with one the least positive and six the most. Blood tests can be utilized in individuals afflicted with a severe case of eczema since this type of testing can not be influenced by antihistamines.

Following the drawing of blood samples, it is then sent away to the laboratories for further evaluation. Blood tests can be pretty much expensive and results are not immediately available for the patient to know whether they are allergic to certain food or not.

Eventually, an allergy is diagnosed when the medical professionals detected the presence of the immunoglobulin E or IgE in the patients blood. But the results of the blood test can not identify if there is a close connection between the existence of IgE and the allergys intensity. There are even cases wherein the results are negative although the patient manifests symptoms of food allergy.

In case, blood tests fail there are still other tests that the medical professionals may utilize to size up your allergy. These tests may include skin prick tests, elimination diets, and food challenges.

Furthermore, feel free to ask questions to the medical professionals concerning the results to better understand your condition.

Food Allergy and Asthma

There have been a lot of studies about food allergy that involves patients having asthma. You can easily see the symptoms after a couple of hours after eating a certain kind of food. Asthma and eczema are associated with atopic patients with allergies in food.
Atopy has three manifestations including asthma. It is an allergy pattern unknown to most patients. It is usually associated with disorders such as hay fever and eczema. Food allergy causes delayed or immediate asthma patterns. The delayed pattern can bring about bronchitis and/or chronic asthma. The immediate reactions are life threatening, dramatic, and sudden that is a consequence of an anaphylactic reaction to food.

Asthma basic ideas, causes, treatment:

– asthma is considered an allergy unless proven otherwise
– allergies come from food sources and airborne
– solve asthma through diet revision and improved air quality

There are three basic choices for the treatment of asthma including removing the cause, treating the symptoms, and altering the patient to tolerate such causes.

Oftentimes, asthma is known as an allergy that’s airborne, and food allergy is greatly neglected. Most doctors overlook this fact and despite the improvements with drug therapies, asthma is a leading cause of death. Most of the skin tests conducted to patients with asthma are negative, and the symptoms dont appear immediately. For some, it can take hours or even days.

How does this happen? If the person eats a type of food that he or she is allergic to, the food allergens are then incorporated into the bloodstream and it triggers the immune mediators’ release. These chemicals can cause different symptoms like bronchial muscle constriction; and this is an episode of an asthma attack. You will slowly feel the reduction of airflow in your bronchial tubes. You’re already having a noisy and prolonged expiration. This obstructive, inflammatory phase is an important mechanism associated with chronic asthma.

Patients with food allergy are usually given antibiotics over and over again because the infection and allergic symptoms are very similar. But the truth is antibiotics can actually increase your risk of advance allergic reactions. There have been reports about patients with long-standing deterioration after prolonged or repeated antibiotic use. This is one of the reasons why many asthmatic patients are quite hesitant to undergo medication.

Here’s good news to asthma sufferers, with a complete revision in your diet, you can remove the chronic symptoms. You must have a broad management plan that includes solving your food allergy, toxicity, airborne allergy, and providing appropriate medication when certain preventive efforts are unsuccessful.

There are specialized doctors that can help you with your diet plan. If your asthma is indeed caused by certain food allergies, your doctor can help you in identifying which foods you’re allergic to. Once the foods are identified, your doctor can now recommend a new diet plan that is designed to stay away from certain foods. This may take time and you need to visit your doctor periodically. But the results are quite effective according to come patients.

If you’re not that sure, you can do a valuable research online and check if the there are doctors in your place that can help you with your food allergy. You can also ask your friends and co-workers if they know a reputable doctor who can help you out.

Dont start any treatment or diet without proper diagnosis and approval of your doctor to avoid any complications.
