TotalIgE - test in allergy diagnosis
Allergy is one of the diseases of civilization. From year to year
the number of patients suffering from allergic diseases increases
It is estimated that currently about 30-40% of Poles have an allergy to an agent of
contact, inhalation or digestive agent.
Total IgE what is it?
Diagnosis of allergic diseases uses, among other things, the examination of the
IgE concentrations, allergy tests, and additional tests performed to exclude
to exclude other diseases such as dermatological diseases. The test of IgE
total is an auxiliary diagnostic test that
is performed in patients with suspected parasitic or allergic diseases
allergic diseases. The test is performed from venous blood.
When to test total IgE?
The test is performed as an adjunct if a person has
symptoms that may suggest an allergic disease, such as skin lesions,
urticaria, allergic eczema. The basis for determining the concentration of IgE
are also based on gastrointestinal and respiratory symptoms.
In allergology, the determination of total IgE concentration supplements the
results of other tests, especially skin tests. The test is also
helpful in the diagnosis of parasitic diseases, such as tapeworm or
pinworms.
Total IgE how to prepare for the test
Total IgE testing requires no special preparation
Before the blood draw, you can drink a glass of water or light,
unsweetened tea and allow yourself to rest for a while
It is recommended to sit and breathe quietly for 10 to 15 minutes
before the blood draw. The patient does not need to be fasting.
Total IgE who should test?
Total IgE testing should be performed whenever recommended by a
them by the attending physician or specialist diagnosing the patient
for allergic diseases, allergic asthma, or parasitic diseases.

parasitic diseases.
The test is performed in adults and children, often along with
the performance of skin tests or allergic blood tests. Although
testing of total IgE concentration is characterized by lower sensitivity
than skin tests, these antibodies are determined during the
diagnosis of allergies.
IgE total standards
The serum IgE antibody standard varies between adults and
children.The concentration of serum IgE is closely related to the age of the
Patient. It is assumed that in adults, the concentration of antibodies should not
should exceed the value of 100 IU/ml. The values for children are
lower, moreover, norms may vary depending on the
laboratory performing the test.
The result of a total IgE test must not be interpreted
alone, since the determinant is not only whether the
concentration of antibodies is not only whether it is within the norm or not, but also,
How far it was exceeded and what symptoms the patient reported before the test.
>>The result of the total IgE test should not be interpreted on its own, because the determinant is not only whether the antibody concentration is normal or not, but also
before the test was performed.
The test result should be confronted with data from the medical history, which is the basis for the diagnosis
