Description

The level of Interleukin 6 (IL6) in the blood is measured using this test. Interleukin 6 is a cytokine, a protein involved in the immunological response of the body. IL6 levels are generally low or undetectable. However, autoimmune disorders, inflammation, infection, some types of cancer, and heart disease can all cause them to rise. While elevated IL6 levels can indicate that a person is suffering from an inflammatory illness, it cannot pinpoint the cause of the inflammation. Therefore, before a diagnosis may be made, more testing is usually required.

An IL6 test may be ordered as a follow-up following a high CRP result. IL6 levels can also track the progression of diseases such as cardiovascular disease, diabetes, lupus, sepsis, and stroke.
