Diagnosis
Your doctor will talk to you to find out more about your symptoms to diagnose your eczema. Your skin will be examined and your medical history. You may also have to undergo various tests to identify allergies and rule out the risks of having other skin diseases [6]. If you suspect that your child is having rashes due to a certain food, you can speak to your doctor about potential food allergies.
Patch Testing
Patch testing involves applying small amounts of different substances to your skin and covering them. It is often used to detect the presence of various skin conditions. Your doctor will observe the skin for any signs of reaction. Patch testing can also be used to diagnose certain types of allergies that are responsible for dermatitis.
