Test Overview

Test Methodology

Detection of IgG anti-intercellular substance (ICS) and anti-basement membrane zone (BMZ) antibodies by indirect immunofluorescence technique using Rhesus monkey esophagus substrate and human NaCl split-skin substrate.

Test Usage

Confirming a diagnosis of pemphigoid, pemphigus, EBA, or bullous LE. Monitoring therapeutic response in patients with pemphigus.

Reference Range

Negative in normal individuals. Report includes presence and titer of circulating antibodies. If serum contains anti-basement membrane zone (BMZ) antibodies on split-skin substrate, patterns will be reported as: 1) epidermal pattern, consistent with pemphigoid or 2) dermal pattern, consistent with epidermolysis bullosa acquisita.

* Reference ranges may change over time. Please refer to the original patient report when evaluating results.
