Food Allergies/allergy test reactions

Question
hello doctor, i am scheduled to have an allergy skin pricking test tomorrow and have read some details on the internet that some people can have very bad reactions to this type of test. I read that some people can have severe allergic reactions to this test, that the reaction can go beyond the arm that they used to test on to the rest of the body and how some even developed anaphylaxis (may have spelled that wrong). I did this test years ago and had nothing go beyond the spots for which they used for testing. Im abit concerned on this, especially when i leave the office and if something worse develops after the appointment. could this happen ones appointment is over

Answer
There are two kinds of allergy skin tests: 1. Intradermal tests in which allergen is injected into the skin. This has generally been abandoned because of a high rate of systemic adverse reactions. 2. Skin prick testing SPT's.

SPT's are extremely well tolerated. However testing with just a few agents (such as penicillin) can be hazardous. In general, while nobody can ever guarantee anything, SPT's using the usual commercial allergen extracts are remarkably safe. I must have performed these tests on tens of thousands of people and never once have I seen a systemic reaction.

People like telling you horror stories. But usually that reflects more on that individual's personality than it does on any true allergy.

Expertise

Any in the field I believe. Only experience of questions that get asked will tell.

Experience

I am a retired medical academic from the UK. I have done major research on Food Allergy and have been a government adviser in the area. 30 years experience running an allergy clinic. And undergraduate and post-graduate teaching.

Organizations
Well, apart from the FRCP, I'm no longer active in the area. I'm too busy writing books. And I no longer have the cash to go to international meetings. But was active in many.

Publications
Will 120 scientific papers help? Chapters in books. Patient advisory materials. Magazine articles. TV appearances. Live and recorded. National and international invited lectures, etc. It was my job for 40 years. Do you think I count!

Education/Credentials
MD, PhD, Postgraduate Diplomas etc. Fellow of the Royal College of Physicians. etc. But I don't want that put out on the net! Just to let you know!

Awards and Honors
irrelevant.

Past/Present Clients
Too many to count, patients of course and a large number of all sorts of corporate consultancies and considerable work as an expert witness in the Courts. I'm volunteering because your Greek expert has been so helpful, I thought I'd offer something back.
