This test measures the levels of desmoglein III antibodies in your blood. High levels of these antibodies can indicate an autoimmune blistering disorder, such as pemphigus.

• To screen patients suspected to have an autoimmune blistering disorder of the skin or mucous membranes, like pemphigus
• To aid in the diagnosis and monitoring of pemphigus
• To assess the effectiveness of treatment for pemphigus
• To differentiate between different subtypes of pemphigus and other vesiculobullous disorders

• If you are suspected to have an autoimmune blistering disorder like pemphigus based on symptoms like fluid-filled blisters, ulcers, or erosions on your skin or mucous membranes
• If you have been diagnosed with pemphigus and need to monitor your condition or evaluate the response to treatment
• If your doctor is trying to differentiate between different types of vesiculobullous disorders

Elevated levels of desmoglein III antibodies may indicate the presence of an autoimmune blistering disorder such as pemphigus. However, abnormal results do not confirm a diagnosis and should be interpreted in conjunction with other clinical findings and diagnostic tests. Discuss your results with your doctor.

• A small blood sample will be drawn from a vein in your arm.

Pemphigus antibody test

Pemphigus is a group of rare autoimmune blistering disorders that cause painful blisters and erosions on the skin and mucous membranes. It occurs when the body's immune system mistakenly attacks proteins called desmogleins, including desmoglein III, which help hold skin cells together.
