Interleukin-6

Interleukin-6 (IL-6) is a protein produced by the immune system in response to inflammation or infection. The IL-6 test measures the level of this protein in the blood. Increased IL-6 levels may be seen in inflammatory conditions, infections, autoimmune disorders, and some malignancies, and should always be interpreted along with clinical findings and other investigations. IL-6 is a nonspecific inflammatory marker, and elevated levels do not confirm a specific disease.

Doctors may suggest a Interleukin-6 test to find the cause of symptoms like fever, fatigue, or unexplained inflammation. It also helps monitor how well treatments for these conditions are working. Because IL-6 levels can change quickly, this test gives useful information about the body’s current inflammatory state.

Avoid taking biotin for at least 8 hours before sample collection. Inform the doctor about all medications and supplements currently being taken, as some of them may affect the test results and may require discussion with the doctor regarding possible adjustments before the test.

Test result ranges are approximate and may differ slightly between labs depending on the methodology and laboratory guidelines. Do not self-medicate and always consult a doctor to understand the test results correctly.
