I am an eczema patient should I go for ALLERGY ECZEMA COMPREHENSIVE PANEL, SERUM (FEIA) or ALLERGY COMPREHENSIVE PROFILE, SERUM (ImmunoCAP,FEIA).

I am an eczema patient should I go for ALLERGY ECZEMA COMPREHENSIVE PANEL, SERUM (FEIA) or ALLERGY COMPREHENSIVE PROFILE, SERUM
(ImmunoCAP,FEIA).

None of these: Eczema---atopic dermatitis----is NOT an allergy. Allergy tests are not useful, often harmful, for eczema. It is not related to foods. Not "stress" either. It is a genetic defect in the surface of the skin. We have very good technology to help eczema, but no cure. SEE A DERMATOLOGIST. Meanwhile use skin cleansers with pH 6 to 7. Apply a liberal amount of a ceramide cream after washing. A prescripti ...Read more

Diagnosed with asthma+allergic rhinitis 2years.Methacholine challenge test today:Negative.ImmunoCAP(A-IgE):Total 1114, 93.4 IgE(kU/l), good control?

Likely for asthma: If the methacholine challenge was negative,that means your asthma is under good control which is measured mostly by your quality of life, the number of asthma attacks, and your lung function. The IgE level is not included in measuring control. However it has nothing to do with your allergic rhinitis. ...Read more

Dermographism, are skin allergy testing not accurate?

Limited use: Skin testing for allergy is of limited usefulness even when a person does not have dermatographism. The history is the key; skin testing can be confirmatory. Especially, don't conclude that you must severely limit what you do and eat, and where you go, based on skin testing. It's just one piece of information that helps guide decisions. ...Read more
