What this laboratory test evaluates
The Guar Bean Gum (f246) IgE
This test measures your body's allergic reaction to guar gum by checking the levels of specific IgE antibodies. This test is done in a lab and helps providers figure out if you have a food allergy. It's especially useful when skin tests can't be done or might not be safe.
Who might need this test?This test is a good choice if you have skin conditions, have taken antihistamines recently, find it hard to do skin tests, or if there's a risk of a severe allergic reaction from skin testing.
Understanding Your Results:A positive result means you have IgE antibodies against guar gum, but it doesn't always mean you'll get sick from eating it. Only some people with these antibodies have symptoms. A Provider, after a full check-up, should decide if you have a food allergy. Remember, not all food allergies show up in this test.
What type of sample is required for this test?0.3 mL serum.
