Answer:
Doctors can diagnose some skin problems by how they look. For other problems, they will use skin tests. Your doctor will first examine you and ask about your medical history. They may check to see if your skin problems may be caused by psoriasis or other chronic conditions. Skin tests can help to diagnose allergies, infections, and other problems affecting the skin. There are also used to tell the difference between malignant (cancerous) cells and benign (noncancerous) cells.
The most common skin tests include:
Patch testing: Patch tests are used to diagnose skin allergies. Allergens (substances that a person may be allergic to) are applied to the skin on the back with adhesive patches and left for a period of time. The skin is then examined for any reaction.
Skin biopsy: Skin biopsies are used to diagnose skin cancer or benign skin disorders. During a skin biopsy, skin is removed (after a local anesthetic is applied) and is taken to a laboratory for analysis. The skin may be removed with a scalpel, razor blade, or a cylindrical punch biopsy tool. Stitches may be used to close the wound.
Culture: A culture is a test that is done to identify the microorganism (bacteria, fungus, or virus) that is causing an infection. Skin (surface scrapings, biopsies, contents of pus bumps and blisters), hair, or nails may be cultured.
