Allergy Test Class 3
Does a class 3 allergy require an epi pen? My daughter just got diagnosed with a class 3 peanut allergy.
Need epipen (epinephrine): Numbers do not always correlate well with severity of eventual reaction, so I wouldn't say she's safe because it's only a level 3. For something like possible peanut allergy, I'd discuss/consult with an allergist because this situation could be life or death ...Read moreSee 2 more doctor answers
Allergies occur when your immune system is triggered by envirionmental factors it should ignore--for example, pollen in the air, or dander on a cat or dog--and creates cells to fight against them. An allergic reaction typically causes itching, congestion, or drainage, and ...Read more
Herpes IgM Immunoglobulin test result - 0.68 gm/l (reference range: 0.4 - 2.4 gm/l), is it positive or negative?
thank you :)
Look again: One should look at the results again. A herpes IgM reference value should be "less than a number" and look something like <1.0 or look like <1:1. The number depends on the lab. If the test result is less than the reference value, then the result means NEGATIVE or no recent infection suspected. The reference value should not be two numbers separated by a dash, so should not look like 0.4-2.4 gm/l. ...Read more
It can happen: Revised reply: disregard earlier one if you saw it. At first I misunderstood the question. The newer TP specific IgG/IgM tests (EIA etc) and RPR/VDRL have similar seroconversion times, typically 4-6 weeks. The IgG tests often are positive first, but exact frequency of this isn't yet known -- more study needed. Apologies again if any confusion from earlier reply. ...Read moreSee 1 more doctor answer
Do sweet gum and hackberry trees have pollen? My allergy test tested positive with a 3 . Rated on 0-6 scale
That Depends: On the part of the lipid profile that you are trying to treat. Are you wanting to know new statins? Fibrates? Statin/niacin combos? Statin/zetia combos, new omega-3 products. Most recent (and potent) statin was crestor, (rosuvastatin) new omega-3, epa only fish oil: vascepa, newer fibrates: antara, trilipix... I also like doing advanced cardiac genetics and expanded lipid profiles! ...Read moreSee 1 more doctor answer
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

Allegra (fexofenadine) -d 12 hour allergy & congestion can show up on a drug test as amphetamine?
Postive, high, rast test results - only hayfever and animal reactions though? Are rast tests reliable?
RAST vs skin tests: The reason allergists prefer skin tests to rast tests is because the skin tests show your body's biological response to allergens. Rast tests only measure the amount of antibody and do not predict its clinical binding and symptom-provoking abilities. That said, no test is perfect. All have to be compared to your experience and correlated with your history. Allergists spend more time doing this. ...Read more
Does desensitization vaccination works for allergic asthma?I got positive skin prick tests for 4-5 allergens....
Yes: It is effective about 80% of the time. However I'd doubt that getting allergy shots for 4-5 allergens would work for you since most people are allergic to dozens of airborne allergens except in the case of occupational exposure. ...Read more

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