Interleukin-6 (IL-6) may be used to help evaluate a person who has a condition associated

with inflammation, such as lupus or rheumatoid arthritis, or with infection, such as

sepsis. It may also be used in the evaluation of diabetes, stroke, or cardiovascular

disease.The reported values for IL-6 in the blood of healthy donors varied between 0 and

43.5 pg/ml. The pooled estimate of IL-6 was 5.186 pg/ml (95% confidence interval [CI]:

4.631, 5.740).
