Serum or Plasma Anti-Septin 7 Immunoglobulin G (IgG) Level
This test measures the amount of antibodies (specifically Immunoglobulin G, or IgG) directed against Septin 7 in your blood. Septin 7 is a protein involved in cell structure and function, and antibodies against it may be detected in certain autoimmune or inflammatory conditions.
["This test helps evaluate immune responses related to Septin 7, which may be important in diagnosing or monitoring certain autoimmune or systemic diseases."]

Why This Test Might Be Ordered
Your healthcare provider may recommend this test if they suspect an autoimmune condition, such as systemic lupus erythematosus (SLE) or other connective tissue disorders, where antibodies against specific proteins (autoantibodies) are known to play a role. It could also be part of a broader evaluation for unexplained symptoms like chronic fatigue, joint pain, or other systemic symptoms.
What to Expect Before the Test
No special preparation is typically needed for this test. You may have a blood sample drawn from a vein in your arm, similar to other blood tests. If you are on blood thinners or have a history of bleeding disorders, let your provider know before the test.
What the Test Results Mean
The test measures the concentration of IgG antibodies against Septin 7 in your blood. While elevated levels may suggest an immune response, such as in autoimmune conditions, normal levels do not definitively rule out these conditions. Results should be interpreted by your healthcare provider in the context of your overall health and symptoms.
Common Conditions Monitored
This test may be used to monitor or diagnose conditions where autoantibodies against Septin 7 are suspected, such as certain autoimmune rheumatic diseases. It is not a standalone test but may be part of a comprehensive evaluation.
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.
