How
are allergies diagnosed?
The cause of an allergy is verified through different allergy tests,
which is performed by a clinical immunologist. These are the following:
Skin test
- injecting a solution of suspected allergen into the skin to find out
if there is IgE immunologic hypersensitivity is done in this allergy
test. Within 15 minutes, a tiny and reddish hive will appear to the
area where the test was done; this indicates that the person is
allergic.
This allergy test helps in detecting whether a person is allergic to
certain types of foods, drugs and insects.
- Rast
Test - (radio-allergosorbent test). A person may be allergic to
certain allergens if the outcome of the test shows that the amount of
IgE antibodies is higher than certain allergens.
- Complete
blood cell count - this allergy test is done to identify if
there is an increase in eosinophil white blood cell count. When white
blood cell count is above the normal number of white blood cells, it
can be a sign that an allergen may be present.
