A low or high total protein does not indicate a specific disease, but it does indicate that some additional tests may be required to determine if there is a problem. The body must have iron to make hemoglobin and to help transfer oxygen to the muscle. If the body is low in iron, all body cells, particularly muscles in adults and brain cells in children, do not function up to par. If this test is low you should consider getting a Ferritin test, especially if you are a female who still has menstrual cycles. These are fats used as fuel by the body, and as an energy source for metabolism.
Increased levels are almost always a sign of too much carbohydrate intake.
Decreased levels are seen in hyperthyroidism, malnutrition and malabsorption. Low levels indicate low fat diet, malabsorption, or carbohydrate sensitivity. The CO2 level is related to the respiratory exchange of carbon dioxide in the lungs and is part of the bodies buffering system. This is one of the most important tests that we measure. Most people have too much acid in their body.
