There are many different ways to test for eczema, both from home and at the doctor's office. Sometimes doctors or skin specialists are able to diagnose an outbreak of eczema simply by looking at it, but will take a deeper look to be sure. Doctors will ask for family history to rule out triggers like food allergies, hay fever, or other irritants. Additionally, doctors will gather information about the lifestyle and diet of the patient, as well as what the inflammation looked like when it was first noticed.

After gathering information and observing the afflicted area, some doctors will order a blood test. In a blood test, the blood is exposed separately to a number of different allergens. If the patient is allergic to any of the allergens, more antibodies will be created when the blood is exposed to them. 

Another test performed is a skin patch test. This test is done to determine if specific irritants cause a reaction of eczema. An adhesive patch is covered in the irritant, which is then placed against the skin. As a control for the experiment, another adhesive patch, without any irritants, is pressed against the skin as well. These patches are left on the patient for a day or two and then removed. If the patient is allergic to the irritants, the skin may be red, inflammed, or itchy. 

Eczema outbreaks can occasionally look like other skin diseases. When these cases arise, doctors will order a skin biopsy to rule out other diseases.

Eczema has no known cure, so the treatment for it is to simply keep it under control. This means preventing it from becoming worse and making the patient more comfortable. Treatments are sometimes developed by altering the patient's lifestyle, diet or medications, but these are on a case by case basis. 

One of the most common methods of treatment for eczema is the use of a cream. Keeping the skin well hydrated is extremely important in controlling eczema. Dryness can lead to more severe breakouts of eczema and increase itchiness. Scratching can lead to infections, so keeping the skin well moisturized is a must. Steroid creams are often used to reduce the inflammation and help the skin begin to heal.

In addition to treatments from the doctor's office, there are a few home remedies that can be done. Sometimes eczema breakouts are triggered by laundry detergents, soaps, or perfumes, and by simply switching these, eczema can be easily controlled. Sweat can irritate eczema, so avoid strenuous exercise and always wear cool, loose clothing.

Eczema has no cure, but with a little treatment, the symptoms can usually be controlled and monitored to help provide as much comfort as possible.
