Total protein is a measure of albumin—the main protein in the blood produced by the liver and globulins which include enzymes, antibodies, hormones, carrier proteins.

  • Elevated levels could indicate dehydration or high levels of albumin and/or globulin as a result of chronic inflammation or infections such as viral hepatitis or HIV. May be associated with bone marrow disorders such as multiple myeloma
  • Low total protein levels can indicate a liver or kidney disorder, malnutrition, malabsorption, celiac or inflammatory bowel disorder.
