Understanding Lab Tests for Mucous Membrane Pemphigoid
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Mucous membrane pemphigoid is a rare autoimmune blistering disorder that primarily affects the mucous membranes, including the mouth, eyes, nose, throat, and genital areas. This condition occurs when the immune system mistakenly attacks proteins that help bind the skin layers together, leading to painful blistering and scarring.
Recommended Test
Bullous Pemphigoid BP230 Antibody
This blood test detects BP230 antibodies, which are autoantibodies that can be present in mucous membrane pemphigoid cases. While this condition is more commonly associated with BP180 antibodies, BP230 antibodies may also be found in some patients, making this test valuable for comprehensive diagnosis and confirming the autoimmune nature of the blistering disorder.

Diagnosing Mucous Membrane Pemphigoid
While the diagnosis of mucous membrane pemphigoid typically involves clinical examination and tissue biopsy, blood tests play a crucial role in detecting specific autoantibodies that confirm the autoimmune nature of the condition. These antibody tests help distinguish mucous membrane pemphigoid from other blistering disorders and guide appropriate treatment decisions.
Understanding the Test Results
The presence of BP230 antibodies in the blood supports the diagnosis of mucous membrane pemphigoid, particularly when clinical symptoms and other diagnostic findings are consistent with the condition. However, not all patients with mucous membrane pemphigoid will test positive for these antibodies, and the diagnosis may require additional testing and clinical correlation.
