Understanding Lab Tests for Pemphigoid Gestationis
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Pemphigoid gestationis is a rare autoimmune blistering skin condition that occurs during pregnancy or shortly after delivery. While diagnosis is primarily made through clinical examination and skin biopsy, blood tests can provide valuable supporting evidence by detecting specific autoimmune antibodies.
Recommended Test
Bullous Pemphigoid BP230 Antibody
This test detects BP230 antibodies in the blood, which can be present in some patients with pemphigoid gestationis. While this condition is more commonly associated with BP180 antibodies, the presence of BP230 antibodies provides additional supporting evidence for the autoimmune process underlying this rare pregnancy-associated skin disease.

The Role of Blood Testing in Pemphigoid Gestationis
Blood tests alone cannot definitively diagnose pemphigoid gestationis, but they are fundamental for detecting autoimmune antibodies that support the diagnosis. These antibodies target proteins in the skin, leading to the characteristic blistering seen in this condition. Testing helps confirm the autoimmune nature of the disease and can guide treatment decisions.
Understanding the Results
The presence of BP230 antibodies in pregnant women with characteristic skin symptoms can help support the diagnosis of pemphigoid gestationis. However, these results must be interpreted alongside clinical findings and other diagnostic methods by a healthcare provider experienced in autoimmune skin conditions.
Important Considerations
