Question 1

on a skin prick allergy test what does a 2e mean?

Accepted Answer

Just a guess: E usually indicate erythema or the red area around the wheal of a skin test.  I would presume that this meant a 2+ reaction on the erythema. In allergy testing however it is the size the wheal and not erythema that counts the most. Perhaps this question can be better answered by the allergist who did the skin test.

Question 2

please tell me how long is a skin prick allergy test supposed to take?

Accepted Answer

Minutes: A trained allergist can place allergy prick skin test in about 2 seconds and interpretation is done at 20 minutes.  The multi-test can place 8 tests at a time to make it even quicker.

Question 3

yesterday i had a skin injection & skin prick allergy test done & tested positive for allergies..afterwards i have felt even worse than usual... it's like all my allergy symptoms have been been amped up & then some..is this a "normal" response?

Accepted Answer

Antihistamine?: Zyrtec is over the counter for non-sedating treatment of allergy. If persists, contact/call back and tell allergy tester of your reaction.

Question 4

are skin prick tests accurate for food allergies?

Accepted Answer

Yes, for ruling out: Skin prick testing is used to see if you might be at risk of developing hives or anaphylaxis after  eating a food. If a skin test is negative, it is unlikely that food is causing that type of reaction. If it positive, you are at higher risk of having hives or anaphylaxis, but there is a chance that it is falsely positive.

Question 5

do they prick your skin or withdraw for 3 hr glucose tolerance test?

Accepted Answer

Blood draw: Finger stick glucoses aren't accurate enough for the test.

Question 6

what is the average cost of a skin-prick allergy test? how many allergens are typically involved in the test?

Accepted Answer

Allergy evaluation: Is what you really need, you may want to see an allergist/immunologist, s/he will decide on what test(s) you need for your case, allergy skin prick test is one of the tools used, average of 15-30 allergens used, including controls, but may need more if your history suggests, cost is between 3-5 $ /prick (allergen), in addition to the consultation. Check a university hospital  with allergy service

Question 7

can you develop an allergic reaction from eating certain type of food within 3 days of eating it even if the skin prick patch test is negative for that food?

Accepted Answer

Allergy is an immune: response. It has to develop AFTER exposure. The skin test is quite reliable, but does not prevent later development of allergy AFTER a negative test. Furthermore, foods are rarely just the food they say it is. Rice is low allergenicity. SAFFRON, artificial colors, various seasonings .. more likely to give allergic responses. So, can have a negative test, same food, difrerent additives.

Question 8

i had a positive allergy test 15 years ago, but never took it seriously. i now think it was correct, should i have another test? 15 years ago, i had a skin prick test & one of the positives was wheat. i was a kid & didn't have noticeable symptoms, so nobo

Accepted Answer

Allergy : Allergy testing would confirm that you have a wheat allergy, but with your constellation of symptoms, you might also speak to your doctor to check for other wheat or gluten related  processes such as celiac disease.

Question 9

is it worth it to allergy test (skin prick) a 3 month baby?

Accepted Answer

Depends: It would depend on the clinical symptoms or reaction which your child has/had.  For example, it can be useful in severe eczematous patients as studies range in a 30-50% rate of a food allergy which could potentially be triggering/contributing to your child's eczema.  This should be discussed in detail with your child's allergy specialist.

Question 10

Accepted Answer
