## Indications for use
Intended Use: The ABL80 FLEX CO-OX analyzer is a portable, automated analyzer that measures pH, blood gases, electrolytes, glucose, and oximetry in whole blood. The ABL80 FLEX CO-OX analyzer system is intended for use by trained technologists, nurses, physicians and therapists. It is intended for use in a laboratory environment, near patient or point-of-care setting. Indications for use: These tests are only performed under a physicians order: pH, pO2,and pCO2, : pH, pCO2 and pO2 measurements are used in the diagnosis and treatment of life-threatening acid-base disturbances. Potassium (cK+): potassium measurements are used to monitor electrolyte balance in the diagnosis and treatment of disease conditions characterized by low or high blood potassium levels. Sodium (cNa+): sodium measurements are used in the diagnosis and treatment of aldosteronism, diabetes insipidus, adrenal hypertension, Addison’s disease, dehydration, inappropriate antidiuretic secretion, or other diseases involving electrolyte imbalance. Calcium (cCa2+): calcium measurements are used in the diagnosis and treatment of parathyroid disease, a variety of bone diseases, chronic renal disease and tetany. Chloride (cCl-): chloride measurements are used in the diagnosis and treatment of electrolyte and metabolic disorders such a cystic fibrosis and diabetic acidosis. Glucose (cGlu): glucose measurements are used in the diagnosis and treatment of carbohydrate metabolism disorders including diabetes mellitus, neonatal hypoglycemia, and idiopathic hypoglycemia, and of pancreatic islet cell carcinoma. Total Hemoglobin (ctHb): total hemoglobin measurements are used to measure the hemoglobin content of whole blood for the detection of anemia. sO2: oxygen saturation, more specifically the ratio between the concentration of oxyhemoglobin and oxyhemoglobin plus reduced hemoglobin. FO2Hb: oxyhemoglobin as a fraction of total hemoglobin FCOHb: carboxyhemoglobin measurements are used to determine the carboxyhemoglobin content of human blood as an aid in the diagnosis of carbon monoxide poisoning. FMetHb: methemoglobin as a fraction of total hemoglobin. FHHb: reduced hemoglobin as a fraction of total hemoglobin.
