Creatinine (Kidney Function)

Creatinine is a waste product formed by the breakdown of creatine important for converting food into energy. The creatinine is filtered out of the blood by the kidneys and then passed out of the body in urine. If the kidney cannot function  normally, the amount of creatinine in the urine decreases while the amount of creatinine in the blood increases.

Hemoglobin A1c (Glycohemoglobin)

Hemoglobin is the substance in red blood cells that carries oxygen. Glycohemoglobin is a form of hemoglobin that has blood sugar (glucose) bound to it. Test results help monitor the long-term control of blood glucose levels in people with diabetes. Most doctors consider the glycohemoglobin A1c level most effective in monitoring the control of diabetes.
