Allergy testing

A high percentage of patients with Central Sensitivity Syndrome have sensitivity to food, chemicals and respiratory allergens or antigens.

In this Unit we have different tests to determine the patient’s degree of sensitivity to the different allergens or antigens in question. In the case of chemicals or respiratory allergens, different tests can be performed in the laboratory or on the patient himself.


Skin tests on the patient


A drop of extract is placed on the patient’s forearm to determine sensitivity and a lancet is pressed on it to bring the liquid into contact with the epidermis or dermis where the mast cells are located. They then release chemical mediators producing symptoms of allergic reactions, red and/or swollen skin. This provides information about the degree of allergy and the protocol to be followed. The extracts used in this type of test are manufactured by Spanish and international laboratories and can be food and/or pneumo-allergenic.

Prick by prick

It is a modified prick-test in which natural extracts are used to test a greater number of allergenic substances. The aims is also for the extract to come into contact with the dermis to analyse the type of reaction in each patient.

Patch test

This test consists in the application of patches on the upper back for a period of 24 hours. They are then removed and the results are read at 48 and 72 hours. This type of test is usually used in the study of sensitivity to chemicals, cosmetics, soaps, etc.
