Description
Why It’s Done:
• To assess inflammation: IL-6 is a key marker of acute and chronic inflammation. The test is used to evaluate conditions such as autoimmune diseases, infections, and inflammatory disorders.
• To monitor chronic diseases: High IL-6 levels are associated with conditions such as rheumatoid arthritis, cardiovascular diseases, diabetes, and certain types of cancer.
• To evaluate cytokine storms: IL-6 levels can be used to monitor patients with severe infections, such as COVID-19, where excessive immune response leads to cytokine storms.
• To assess response to treatments: For patients undergoing treatment for inflammatory or autoimmune conditions, the IL-6 test can help monitor the effectiveness of therapy, especially for biologic drugs targeting IL-6.
Preparation:
• Fasting is not usually required, but follow any specific instructions from your healthcare provider.
• A blood sample will be drawn, typically from a vein in your arm.
• Medications: Inform your healthcare provider about any medications you are taking, especially immunosuppressants, biologic drugs, or steroids, as these can affect IL-6 levels.
• Avoid alcohol and strenuous activity before the test, as they can influence inflammation markers.
