Allergy Classes (what are they?)

Hobbes

I am trying to find details on the allergy classes but google isn't helping me.

So what class I,II,..,VI, etc reaction mean?

Hobbes

I am asking for Allergy classifications, yet only Type I there is listed as an allergy. It is not a subject matter I am familar with, hence asking.

You think you can offer anything other then crass comments?

[edit] To anyone else, so as I understand it the Type determines how quickly the effects of the allergy take place?

Not just the OP, to be fair. We like to keep banter to the off-topic threads because people are usually at the end of their teather when they post here, and are sensitive to slagging. You didn't know, but now you do, so just bear it in mind in future, cheers.

Hi,

I could be totally incorrect but the only numbers I know in terms of Allergies is related to Rast Blood Test. I have not really have hear of any other typing of Allergies.

I found this on Google.


" Specific IgE tests are usually returned in units of micrograms per milliliter (μg/mL). Some, however, are returned on a numerical rating scale (often, but not always, from 0 to 5 or 6). On rated tests, 0 almost always indicates an exceedingly low chance of a true food allergy, while the higher numbers normally mean very strong probability of allergy and a strong likelihood of a severe reaction. Your allergist may use these results to help determine some aspects of your treatment -- to see whether a child is showing signs of outgrowing a food allergy, for instance."

Dont know if it is of any help.

If you google for hypersensitivity response you'll get more information.

Please take the following with a pinch of salt.

There are four types of hypersensitivity response.

Type 1. An antigen and a cell bound antibody.
This is an immediate response, within a few minutes. It occurs quickly because a person has had prior exposure and is sensitized. An example would be hayfever.

Type 2. An antibody and a cell bound antigen.
This occurs in minutes or hours. An example would be a person getting the wrong blood in a transfusion.
There are two types, depending on the pathway causing damage to the cell.
Examples would be multiple sclerosis, Graves' disease and is also involved in early transplant rejection.

Type 3. Preformed antibody and antigen complex.
These complexes can accumulate in in tissue, commonly in the kidneys, skin and joints. This causes inflammation and tissue damage.
There are 3 types:
1) after an infection, causing kidney disease
2) autoimmune ( Rheumatoid arthritis, Systemic lupus erythematosus )
3) exposure over time, inhalation of dust on a farm leading to farmer's lung

Type 4. T-cell mediated, these cells involved in the immune system.
This would be seen in transplant rejection.

Hope that's of some help.

Contraindicated for those hypersensitive to salt, I presume

Cheers. I was trying to decode an allergy test results. The other part was an upper limit of IgE 428 kU/I. But it doesn't detail in relation to what, or is that overall?

Results for IgE often give the threshold limit (depends on the lab, but afair 80 (whatever the standard irish unit is) is commonly used ) after which a positive or abnormal result can be assumed.
Upper limits probably refers to the maximum amount the test can measure, anything above that can't be accurately determined.

you need to speak to whoever did the test for you, as we cant give specific medical advice here

Yea I plan to do that thanks (have an appointment). It was more trying to decode what they were saying as the letter was written for the GP rather then for public consumption.

Total IgE of 428 is certainly higher than it should be - but that is not proof of relevant clinical allergy. It is only when some of that IgE is specifically directed against an allergen that clinical allergy ensues.
