## Indications for use
The EasyRA sodium test is intended for the quantitative determination of sodium ions (Na') in human serum, plasma and urine using the MEDICA EasyRA Chemistry Analyzer with the ISE module option in clinical laboratories. Sodium measurements are used in the diagnosis and treatment of aldosteronism, diabetes insipidus, adrenal hypertension, Addison's disease, dehydration, inappropriate antidiuretic hormone secretion, or other diseases involving electrolyte imbalance. For in vitro diagnostic use only. The EasyRA potassium test is intended for the quantitative determination of potassium ions (K)5 in human serum, plasma and urine using the MEDICA EasyRA Chemistry Analyzer with the ISE module option in clinical laboratories. Potassium measurements are used to monitor electrolyte balance in the diagnosis and treatment of diseases conditions characterized by low or high blood potassium levels. For in vitro diagnostic use only. The EasyRA chloride test is intended for the quantitative determination of chloride ions (CI-) in human serum, plasma and urine using the MEDICA EasyRA Chemistry Analyzer with the ISE module option in clinical laboratories. Chloride measurements are used in the diagnosis and treatment of electrolyte and metabolic disorders such as cystic fibrosis and diabetic acidosis. For in vitro diagnostic use only. The EasyRA carbon dioxide reagent is intended for the quantitative determination of Bicarbonate/Carbon Dioxide in human serum and plasma, using the MEDICA "EasyRA Chemistry Analyzer" in clinical laboratories. Bicarbonate/carbon dioxide measurements are used in the diagnosis and treatment of numerous potentially serious disorders associated with changes in body acid-base balance. For in vitro diagnostic use only.
