patch test اختبار
A patch test اختبار is a type of allergy test that is used to identify the specific substances that may be causing an allergic reaction on a person’s skin. It involves applying small amounts of various substances, known as allergens, to the skin on the person’s back, typically using adhesive patches. Along with your medical history, allergy tests may be able to confirm whether a particular substance you touch, breathe or eat is causing symptoms.
Patch testing is often used to diagnose contact dermatitis, a type of skin inflammation that is caused by exposure to specific allergens or irritants. The test can help identify the specific substances that are triggering the reaction, which can help the person avoid those substances in the future and reduce their symptoms.
Patch test اختبار can detect delayed allergic reactions, which can take several days to develop.
Patch tests don’t use needles. Instead, allergens are applied to patches, which are then placed on your skin. During a patch test, your skin may be exposed to 20 to 30 extracts of substances that can cause contact dermatitis. These can include latex, medications, fragrances, preservatives, hair dyes, metals and resins.
The patches are usually left in place for 48-72 hours, during which time the person should avoid showering or bathing to prevent the patches from becoming wet. After the patches are removed, the skin is examined for any signs of a reaction, such as redness, swelling, or itching.
Common allergens that may be tested for include metals such as nickel or cobalt, fragrances, preservatives, and chemicals used in hair dyes and other personal care products. In some cases, the testing may also include substances that are specific to the person’s occupation or hobbies.
Patch testing is generally considered safe, but there is a risk of skin irritation or allergic reaction to the substances being tested. It should only be performed by a trained healthcare professional who can monitor the person’s reaction and provide appropriate treatment if necessary.
If you are experiencing symptoms of contact dermatitis, such as redness, itching, or rash, it’s important to seek medical attention to determine the underlying cause and develop an appropriate treatment plan.
