Description
Serum, NA, Fasting or Non Fasting: As suggested by doctor
Sample Required:
The VGKC (Voltage-Gated Potassium Channel) Antibody test requires a blood sample. A standard blood draw is performed to collect the necessary sample.
Test Time:
The results of the VGKC Antibody test are typically available within a few days, depending on the laboratory’s processing time.
Test Normal Range:
The VGKC Antibody test is a qualitative test, and the results are reported as positive or negative based on the presence or absence of specific antibodies.
What is the Test:
The VGKC (Voltage-Gated Potassium Channel) Antibody test is used to detect antibodies directed against two specific proteins: LG1 (Leucine-Rich Glioma-Inactivated 1) and CASPR2 (Contactin-Associated Protein 2). These antibodies are associated with a group of neurological disorders known as autoimmune encephalitis. Autoimmune encephalitis is characterized by inflammation of the brain and neurological symptoms.
Test Procedure:
Blood Sample Collection: A healthcare professional will collect a blood sample from a vein in your arm using a sterile needle.
Laboratory Testing: The blood sample is sent to a laboratory for testing. In the laboratory, it is tested for the presence of LG1 and CASPR2 antibodies using specialized techniques.
When to Take the Test:
The VGKC Antibody test is typically ordered when there is a suspicion of autoimmune encephalitis, especially if an individual presents with neurological symptoms such as seizures, confusion, memory problems, or behavioral changes.
Who Should Take This Test:
Individuals who exhibit symptoms consistent with autoimmune encephalitis, as well as those with a known history of the condition or who have been exposed to potential triggers, may undergo this test. It is typically ordered by neurologists or other specialists.
Precautions for Exceptional Cases (Pregnancy, etc.):
There are generally no specific precautions related to pregnancy for the VGKC Antibody test. However, pregnant individuals with neurological symptoms or a history of autoimmune encephalitis should discuss their concerns with a healthcare provider.
