While I know that I am in the tiny percentage of the population who has a strong negative reaction to the Methacholine Challenge test, I want to offer one caveat. About six years ago, I had chronic cough and my doctor thought I might have asthma so he had me take the Methacholine Challenge test. Taking the test turned my, as yet unknown, asthma into moderate-to-severe persistent asthma. Hope no one else has this experience but it is something to consider.
I've had things I knew I was allergic come up negative on blood tests but positive on skin prick tests and obviously positive when exposed to the allergen. From what I understand there is a difference in allergic responses that isn't always picked up on blood tests, and also that sometimes an allergen has more allergenic components in it than what is looked for on a specific ige blood test but that do often pick up on the skin prick test. I have also heard some allergic reactions are more...
@Shea is absolutely right -- a reaction can indeed occur immediately or 2 - 6 hours (sometimes more) later . Seeing a board-certified allergist is definitely a way to get a more accurate assessment of what your allergies truly are.
Good afternoon, Than you for information you just shared. I work with a parent who's child was sent to two different labs for blood work for allergy for lobster or shellfish after taking the prick/puncture skin test. Mom was very concern about having to go too two different labs for results. How can I help educate her with information that will make her feel better or understand the method used for results.
Welcome, @Natalie Wiggins and thank you for the question. So that we can discuss it in more detail with more people, I'm going to copy your comment into a new topic in the Skin Conditions Support forum: Help Explaining about Different Types of Allergy Skin Tests Let's do a deeper dive there.
So if my children and I suffer from Ezcema,Uticaria,Dermatitis and my children have done allergy test on forearm and upper arm area, can they still be tested with Atopy Patch?
