Although the itchy, red rash you may experience after coming in contact with certain substances is not usually serious, it can be annoying and uncomfortable. The condition is called contact dermatitis and is very common in both children and adults.
Contact dermatitis is a skin inflammation, which occurs as a result of an allergic reaction to an allergen. Allergens are substances, which are not harmful, but the body is sensitive to them, and an allergic reaction occurs. In the case of contact dermatitis, when an allergen comes in contact with the skin, it can trigger a reaction.
There are many things, which may act as allergens in some people. Common triggers of contact dermatitis include cosmetics, lotions and perfume. Jewelry, which is make of nickel is also a common allergen for many people. Household cleaners, rubber and some topical medicines may also cause contact dermatitis.
A red rash or bumps on the skin are the most common symptoms of contact dermatitis. Itching at the site of the rash also often occurs. In some cases, the skin may become dry and cracked and be painful. In severe cases of contact dermatitis, blisters may form and crusting on the skin may develop.
Treatment for contact dermatitis involves visiting an allergy doctor and possibly undergoing skin tests to determine what you are allergic to. Treatments may be as simple as avoiding the allergen. Self-care measures may include applying wet compresses and anti-itch creams to the skin. If medication is needed, your allergist may recommend oral medication to reduce inflammation.
If you have symptoms, which you think may be contact dermatitis or you have other allergy symptoms, don’t continue to suffer. Effective treatment is available. Call Dr. Boyan Hadjiev, one of NYC’s best allergy doctors and schedule your appointment today.
CAP-RAST is a type of blood test, which may be recommended by your allergist to check for allergies.
When you have a reaction to an allergen, your body identifies the substance as harmful and releases a protein called immunoglobulin E (IgE). A CAP-RAST is a blood test which determine if IgE attaches to the allergen. But unlike some other types of blood tests, the CAP-RAST can also measure the amount of IgE directed at the allergen, which helps your allergist determine if you are allergic to a specific food or other allergens.
This type of blood allergy testing is often used in food allergies. Although it can detect the levels of IgE and confirm you are allergic to a specific allergen, the test will not determine how severe a reaction you may have.
The procedure is relatively simple. It involves taking a small amount of blood and applying it to material containing the suspected allergen. A positive reaction to the allergen indicates an allergic reaction is likely. CAP-RAST testing may also be done in conjunction with skin allergy testing to confirm a diagnosis.
In some instances, a CAP-RAST may also be done if skin allergy testing may cause a systemic allergic reaction in highly sensitive patients. One advantage of CAP-RAST testing is medication does not need to be stopped prior to the test. After the test, you allergist will go over the results and explain what the result indicate.
