Desmoglein 1 and Desmoglein 3 (Pemphigus), IgG Antibodies
Also known as: Desmoglein 1 and 3 IgG, Pemphigus Autoantibodies
Use
This test is a preferred screening test for patients suspected to have an autoimmune blistering disorder of the skin or mucous membranes (pemphigus). This test aids in the diagnosis of pemphigus. The antibody levels can be used to monitor the effectiveness of drug treatment.
Special Instructions
Serum samples must be stored for up to eight hours at room temperature before freezing at -20°C. Dissalow repeated freezing and thawing of samples to maintain stability.
Limitations
The stability of serum samples at room temperature and refrigerated conditions is not guaranteed, hence they require freezing at -20°C for prolonged storage. Freeze/thaw cycles should be kept to a minimum (no more than three) to ensure sample integrity. Bacterial contamination, hemolysis, and lipemia can lead to sample rejection, as they may interfere with accurate test results.
