Decoding Allergy Tests: Understanding Your Report
Imagine your body has an army that fights off bad things like germs.
Sometimes, this army mistakenly attacks things that aren't harmful, like pollen.
An allergy test helps doctors figure out what your army is wrongly attacking.
There are two main tests: one pokes your skin, and the other checks your blood for special fighters called IgE.
The tests give numbers and 'classes' that show how strong your body's reaction is to different things.
But remember, these numbers don't always match how sick you feel.
Talk to a doctor to understand what your tests mean for you.
Allergy tests help identify substances that trigger an immune system overreaction.
There are two main types of allergy tests: Skin Prick Tests and blood tests.
The IgE value represents the concentration of antibodies in your blood.
Labs classify IgE results into levels or classes.
Allergy test results show probabilities, not definitive yes-or-no answers.
