Blood test

Blood test

For allergies, it is useful to take a blood sample to dose the IgE (immunoglobulin type E) both total and specific. IgE are allergy antibodies (e.g. against pollens or cats). By quantifying specific IgE against a given allergen, we can determine the severity of the immune response to each allergen suspected of causing the allergy.

Taking blood only takes about 5 in our medical practice (lab personnel is present during all office hours). It is not systematically necessary to fast before the test.

IgE dosage  efficiently and accurately completes the basic allergy workup (history, skin tests, spirometry).

As standard practice, our lab technician also checks blood count, any possible eosinophilia, and eventual resulting inflammation.
