Elevated

Has been associated with chronic inflammation and certain blood disorders in research literature.

Lower

Has been associated with liver dysfunction, kidney protein loss, or malnutrition in research literature.

These associations are general. They are not a personal diagnosis or prediction. Discuss your individual results with your physician in the context of your full health profile.
