Clinical Information (ข้อมูลทางคลินิก):
  1. Measurement of pH, pCO2, pO2 (blood gases) is used in the diagnosis and treatment of lifethreatening acid-base disturbances
  2. Measurement of sodium, potassium is used in diagnosis and treatment of diseases involving electrolyte imbalance
  3. Measurement of ionized calcium is used in diagnosis and treatment of parathyroid disease, a variety of bone diseases, chronic renal disease and tetany
  4. Glucose measurements are used in the diagnosis and treatment of carbohydrate metabolism disorders including diabetes mellitus, idiopathic hypoglycemia and of pancreatic islet cell tumors
  5. Lactate measurements are used to evaluate the acid-base status and are used in the diagnosis and treatment of lactic acidosis (abnormally high acidity of the blood)
  6. Creatinine measurements from the epoc Blood Analysis System are used in the diagnosis and treatment of certain renal diseases and in monitoring renal dialysis
  7. Measurement of Hct distinguishes normal from abnormal states of blood volume, such as anemia and erythrocytosis
