The main methods for examining skin itching include: 1. Physical examination: The doctor will carefully observe the patient's skin condition, including characteristics of the itchy areas, skin redness, rash, plaques, blisters, ulcers, etc., as well as the condition of skin in other areas to understand the overall disease status. 2. Blood tests: Including routine blood tests, liver and kidney function tests, which can assess levels of inflammatory markers, allergy indicators, and specific pathological markers in the blood, helping to determine whether there is infection, allergy, or specific diseases. 3. Skin tests: Such as skin prick test, skin scratch test, which are used to determine whether the patient has an allergic reaction to specific substances, thus assisting in diagnosing the cause of skin itching. 4. Laboratory tests: Through laboratory tests such as routine urine tests, other systemic diseases causing skin itching can be ruled out. 5. Skin biopsy: In some complicated or difficult cases, the doctor may choose to perform a skin biopsy, conducting pathological examinations of skin tissue to determine the nature and pathological changes of the skin lesions.
