Skin allergies
Allergy tests may be required for certain types of eczema to identify potential substances which your skin may be allergic to.

Skin prick test

A skin prick test can test for as many as 50 different substances at once such as, pollen, mold, pet dander, dust mites and food. The test is performed by gently pricking the skin’s surface using needles and placing small drops of allergen extracts into the skin’s surface. If you are allergic to any of the tested substances, a raised, red, itchy bump will appear.
Allergy blood tests (Radioallergosorbent test- RAST) can also be performed to identify common food allergies and dust mite allergy. The blood test measures the amount of allergic antibody (IgE) produced when the blood is exposed to specific food allergens.

Patch test

Patch tests are done to see if a particular substance is causing an allergic skin inflammation. Substances that are tested may include latex, fragrances, preservatives and metals. The test can be used to detect allergic reactions that take several days to develop. Allergens are applied to patches and then placed on your skin, usually on the back for 48 hours. Irritated skin at the patch site may indicate an allergy. Subsequent patch test results reading will help to identify any specific contact allergies.
