Skin diagnostics involves determining the cause of skin conditions or lesions. It often begins with a visual examination by a healthcare professional. However, if a visual exam isn't conclusive, further tests are used to reach a precise diagnosis.
Methods of Skin Diagnostics
Several methods are employed in skin diagnostics:
-
Visual Examination: A doctor often diagnoses skin diseases simply by looking at the skin. This includes examining the scalp and other areas. Source: Merck Manual Consumer Version
-
Biopsy: A small skin sample is removed and examined under a microscope. This is a common procedure for diagnosing skin cancer and other conditions where a visual exam is insufficient. A complete removal of the growth may be sufficient to determine the cancer stage.

-
Allergy Skin Tests: These tests identify specific allergens causing reactions. They are considered the gold standard for allergy diagnosis, used alongside medical history.

Determining which diagnostic method is necessary depends on the specific symptoms and the healthcare provider's judgment. The goal is to identify the underlying cause of the skin issue accurately and effectively.
