How is chilblain lupus diagnosed?

A dermatologist (skin care doctor) can diagnose chilblain lupus. Usually, dermatologists use a test called a skin biopsy.

During a skin biopsy, your dermatologist takes a small skin sample. Your doctor sends this sample to a laboratory, where specialists look at it under a microscope. Examining skin under a microscope can tell healthcare providers whether chilblain lupus or another condition is causing skin sores.
