What is Voltage-gated Calcium Channel Antibody (VGCCA)?
This test identifies antibodies that target voltage-gated calcium channels, which are crucial for nerve and muscle communication. Detecting these antibodies helps diagnose certain autoimmune neurological disorders that affect muscle strength and function.
Why is this test important?
VGCCA is primarily associated with Lambert-Eaton Myasthenic Syndrome (LEMS), an autoimmune condition often linked to small cell lung cancer. This test is critical for diagnosing LEMS and guiding treatment, as well as for cancer screening in some cases.
