My dairy-allergic daughter had a blood test about 2 years ago which was about 8.4. She had another blood test last week and now is about 13. The allergist says that the actual number is of no real significance and that anything over 6 is considered to be a true allergy. Anyone else have any input.

He also says that studies are now saying that fewer children are outgrowing dairy allergies. :(

dd also tested positive to an allergy to peaches.

Unfortunately they are starting to say that not all dairy allergies are outgrown now, but that doesn't mean that they can't be outgrown. Hope for the best and prepare for the worst.

Allergy testing is very complex. The blood test can show the presence of IgE's but how allergic a person is or if they are at risk of anaphylaxis is an interpretation of many factors including on the allergen in question, whether the IgE number is increasing with subsequent tests, and other conditions such as asthma. You need a good allergist to interpret your daughters specific situation.

According to Anaphylaxis Canada
http://www.anaphylaxis.org/content/prog ... deaths.asp
Statistics: Ontario 1986-2000

Quote:

Findings:
Of 63 confirmed anaphylaxis deaths, 32 were food-related, 21 were due to bee sting and 10 were due to medication.

Allergens:
Peanut and tree nut represented 20/32 of the food allergens, followed by seafood (3/32), milk, sesame, sulphite and beer (1/32 each). In 3/32 cases, the allergen was undetermined.

Demographics:
There were 17 females and 15 males. Significant age differences were noted between the following three subgroups: peanut/tree nut deaths (n=20) (9-39 yrs, mean = 21.7 yrs), other food deaths (n=12) (17-78 yrs, mean = 41.2 yrs) and insect sting (n=21) (26-74 years, mean = 54.6 yrs) (p<0.0001).

Epinephrine:
Only 11/32 patients had been prescribed epinephrine. 4/11 had it "close by" at the time of reaction and one formulation was 2 years expired. It was difficult to determine the exact timing of epinephrine administration. Two patients died while running to get epinephrine that was within a 100-200 foot radius. Only 8/32 received epinephrine prior to arrival in the emergency room. One had refused to carry epinephrine despite a history of severe reactions and one felt that that they could not afford it.

Were there any other contributing factors?
Asthma was mentioned in 22/32 cases.

My 11 year old son is allergic to dairy and peanuts, he outgrew an egg allergy at about age 8. His peanut reading recently was 19.0 and his milk has come down considerably to 0.48. His allergist has suggested that we challenge him with milk and we have agreed. We are waiting for an appt. for that. We don't want to get to hopeful but at that number, according to our allergist, it's about an 80% chance that he will not have the allergy. We are keeping our fingers crossed. He has been allergic to all three since he was a baby and has outgrown the egg allergy so hopefully that is where we are headed with the milk allergy.
