What is the Test?Â
The C-ANCA (Cytoplasmic Antineutrophil Cytoplasmic Antibodies) test is used to detect the presence of specific antibodies in the blood that target neutrophils’ cytoplasmic granules. These antibodies are associated with certain autoimmune conditions, particularly granulomatosis with polyangiitis (GPA), a type of vasculitis.
Test Procedure:
A healthcare professional will use a needle to draw blood from a vein, usually in your arm. The collected blood sample will be processed in a laboratory to detect the presence of C-ANCA antibodies.
When to Take the Test:Â
This test may be ordered if your healthcare provider suspects an autoimmune condition like granulomatosis with polyangiitis (GPA) due to symptoms such as persistent upper respiratory tract infections, joint pain, sinusitis, or other signs of vasculitis.
Who Should Take This Test:
Individuals with suspected autoimmune conditions affecting the blood vessels and organs. Those with symptoms of GPA, such as respiratory issues, joint pain, and other systemic symptoms.
