Detailed answer

To diagnose eczema, a healthcare professional will first examine the affected skin areas. They will look for specific signs such as redness, dryness, itchiness, and inflammation. The doctor will also review the patient's medical history and ask about any family history of eczema or allergies. Additionally, they may perform patch testing to rule out possible allergic triggers. In cases where the diagnosis is uncertain, a biopsy may be taken for further examination under a microscope. It is important to consult with a qualified healthcare provider for an accurate diagnosis and appropriate treatment plan.
