Blood or prick test for food intolerance?

Blood or prick test for food intolerance?

Neither: No allergy antibodies in food intolerance. That's what we're looking for with blood and skin testing. So testing can rule-out food allergy in a case of food intolerance. The history and physical examination is usually sufficient to make a diagnosis of food intolerance. If testing is recommended skin testing is much less expensive and perhaps a little more sensitive than blood testing. ...Read more

If u have mild milk allergy with prick test negative . The lactose intolerance breath test will be negative or positive ? Please reply thx ...

If u have mild milk allergy with prick test negative . The lactose intolerance breath test will be negative or positive ? Please reply thx ...

Two problems: The skin prick test looks for ige antibodies to a potential allergen. A negative test means allergy is much less likely, but skin tests can miss allergy. Lactose intolerance is not an allergy, so skin testing would not be helpful in a suspected case. The hydrogen breath test can be used to confirm lactose intolerance. ...Read more

Wheat allergy & mostly (not 100%) gluten free diet. Still has gastro issues. Doc testing for Celiac. W/ mostly gluten-free diet will test b accurate?

?which test ?: Testing for celiac varies. There are blood tests, which can show positive with small amounts of gluten intake. (1/10 of a slice of bread)The most dramatic and accepted confirmatory test for celiac disease is a small intestine biopsy.

If I have a positive Quest Diagnostics blood test for a food allergy, could a skin test give a stronger confirmation? So many positives for foods!

If I have a positive Quest Diagnostics blood test for a food allergy, could a skin test give a stronger confirmation? So many positives for foods!

Blood tests: for food allergies are somewhat unreliable - as there are many problems with cross reactivities on the assays. Unless you have had a particular event like you were unable to breathe or throat swelling after eating a particular food and are sure there was nothing else causing it- then these results may not be clinically important. Pollen/ and environmental allergy testing is much more reliable. ...Read more

Are allergy tests for food sensitivites and/or allergies fairly accurate?

Are allergy tests for food sensitivites and/or allergies fairly accurate?

Yes: Allergy testing is fairly accurate for allergies due to ige mediated allergic reactions. Others types of immune and non-immune reactions are not detected by this type of testing. In addition the results of testing need to correlate with (match) the clinical picture and in some instances food and/or drug challenges will need to be dome. See an allergist for evaluation and interpretation of results. ...Read more

How to check for lactose intolerance and gluten allergy?

Depends: Lactose intolerance is mostly a clinical diagnosis--usually leads to GI symptoms after eating foods containing lactose (dairy). Biopsy of the intestine can confirm the diagnosis as well. Celiac disease (gluten sensitivity) can be screened for with blood tests, and the confirmatory test is also a biopsy of the intestine. It's important that these tests be done while you're on a regular diet. ...Read more

Can wheat allergy test comes false positive if a person have hypothroidism?

Can wheat allergy test comes false positive if a person have hypothroidism?

Yes: If the hypothyroidism is caused by an autoimmune process, it is possible for allergy testing of other items to show false positives. I would get the thyroid disease settled down and retest or see allergist about alternative ways to test for wheat allergy that would not cross react with the thyroid antibodies the body is producing. ...Read more

How can doctors test for food intolerances?

How can doctors test for food intolerances?

Define "intolerance": Some food reactions will be triggered by true allergies and blood or skin testing can be suggestive.A high ige level may indicate need for having Epinephrine on hand for reactions. Other "intolerance" may produce indigestion, diarrhea, or other symptoms any time they are consumed. A period off the food, followed by a challenge ingestion would bring on symptoms for a positive test. ...Read more

Can I have celiac if a skin test was negative for wheat allergy?

Can I have celiac if a skin test was negative for wheat allergy?

Yes: Celiac is due to an immune reaction to certain components of wheat protein, gluten/gliadin, but is not due to allergic antibody (ige) to wheat, so skin testing is negative in celiac. Certain blood tests showing immune reactions to certain intestinal enzymes, e.g. Tissue transglutaminase (ttg), are positive in celiac disease. Consult a gastroenterologist. ...Read more
