What tests confirm lichen sclerosus diagnosis?
Diagnosis is mostly clinical, based on examination. A skin (punch) biopsy is the only definitive test if there is diagnostic uncertainty or to rule out cancer.
Detailed Medical Explanation
Specialists diagnose lichen sclerosus mainly by history and inspection. If needed, a punch biopsy will be taken and examined under a microscope by a pathologist. Blood tests are not used for diagnosis. For more, see NHS and BAD.
