Get the Basics on a Food Allergy Blood Test!

 

It is estimated that there are over ten million people in the United States that have some form of food allergies. The symptoms of food allergies can vary, but some of the most common include: swelling of the tongue and throat, difficulty breathing, hives, vomiting or a tingling sensation in the mouth. There are two different types of tests doctors can do to find the cause of food allergies. One is a skin prick test and the other is a food allergy blood test. Depending on the severity of the reaction, a doctor might choose to perform one or both of these tests.

Many children are susceptible to food allergies. Currently there is no cure for these ailments, but it is possible to outgrow them over time. Strictly avoiding the foods that cause the allergic reactions is the best way to prevent future reactions. The problem for some people is that they don't know exactly which foods, or food ingredients are causing the reactions. The skin prick test that many doctors do involves poking an area of the skin and then introducing a food substance to that area. A small welt will form if a person has an allergy to that particular substance.

While the skin prick test is a good way to determine the cause of allergies, the food allergy blood test is a more comprehensive and definitive test. The blood test looks for specific antibodies that show up when allergies are present. By testing the level of these antibodies after certain foods are introduced to the body, doctors can narrow down which foods may be causing the allergic reactions. 

If the skin prick test and the food allergy blood test are not able to determine the cause of an allergy, further testing and observation will be done. Knowing the history of food reactions and symptoms is information that can be invaluable for doctors. The most common type of medication that is used to treat these allergies is Epinephrine. Most people with food allergies carry this medication with them at all times in the form of an EpiPen. Food allergies occur when the immune system reacts to a certain food. The symptoms of reactions can lead to life threatening conditions, and that is why it is so important to deal with any allergic reactions as soon as they happen. Working with a doctor is the best way to determine the cause of reactions, and to set up a treatment and management plan for the future...
