Serum Anti-Septin 5 Immunoglobulin G (IgG) Antibody
This test measures the level of antibodies against a protein called septin 5 in your blood. These antibodies may be present if your immune system is responding to an unusual exposure or condition involving this protein.
["This test helps evaluate potential autoimmune or inflammatory responses related to septin 5."]

Why Might This Test Be Ordered?
Your healthcare provider may recommend this test if you have symptoms or conditions linked to immune system activity involving septin 5, such as certain autoimmune diseases or unexplained chronic inflammation. It may also be part of a broader diagnostic workup for suspected autoimmune disorders or to monitor immune responses in research or clinical trials.
What Does This Test Measure?
The test detects the presence and concentration of IgG antibodies specific to septin 5 in your serum. Septin 5 is a protein involved in cell structure and function, and its role in disease is still being studied. Elevated levels of these antibodies could indicate an immune response, though they may not always correlate directly with disease activity.
Sample Collection and Preparation
A blood sample is drawn from a vein in your arm. The blood is then processed to separate serum, which is the liquid part containing the antibodies being tested. This serum is sent to a laboratory for analysis using an immunoassay method.
What to Expect Before the Test
No special preparation is typically required for this test. You may continue with your usual activities, but avoid heavy exercise or consuming alcohol 24 hours before the blood draw if instructed by your provider.
Reference range
INR: 0.8-1.2 (warfarin: 2.0-3.0)N/A
Inform your healthcare provider if you are taking blood thinners. No special preparation required.
