Allergy blood testing is a trusted method used to check for elevated levels of immunoglobulin E (IgE) antibodies in the blood. Blood tests are a crucial part of the diagnostic process for people who rely on antihistamines or have a skin condition, as skin prick testing would not be suitable. Atlanta allergists will use the test results, symptom analysis and your medical history to make an accurate allergy diagnosis. If you’re scheduled for a food allergy blood test, here’s how to prepare.
How Should I Prepare for Food Allergy Blood Testing?
Food allergy blood testing does not require significant preparation or lifestyle alterations. By following straightforward instructions you’ll be perfectly prepared to have blood drawn and sent to the lab for analysis.
Pay Attention to Food Allergy Symptoms
Monitor and record any food allergy symptoms you experience after eating specific foods. In many cases symptoms will be fairly mild, and can include itching, swelling, stomach pain or a skin rash. With a record of the type and severity of symptoms, your allergist will have a more clear understanding of the allergens to test for.
Start a Food Diary
Recording the foods you eat in the weeks before a test can also help with a diagnosis. After recognizing the signs you need food allergy testing, start to jot down your dietary intake, including those ingredients found in food items that might be responsible for allergic reactions.
Tell Your Allergist About Medication
Many medications can influence the results of an allergy test, so it’s important to let your allergist know what you’re taking. It may be necessary to pause certain medications (including antihistamines or corticosteroids) before the blood test, but you and your allergist will discuss this.
Follow Food and Drink Guidelines
One advantage of blood testing for food allergies is the ability to follow your usual diet without fasting. However, always check with your allergist, as there could be some restrictions. In addition, make sure you are well-hydrated to help with the blood drawing process.
Wear Comfortable Clothing
Sitting down for a blood test is a quick, straightforward process, and wearing a short-sleeve shirt or blouse allows easy access to your arm for drawing blood.
Wait for the Food Allergy Blood Test Results
After your blood draw the samples are sent for analysis. The time to get results back will vary, depending on the tests required and the lab. Your allergist will analyze the results and consider them in the context of your medical history and symptoms. When you receive a comprehensive diagnosis, you can then discuss the food allergy treatment options and begin the process of relieving food allergy symptoms.
