## Indications for use
The SelectaLyte Electrolyte Analyzer (Na+, K+, Cl-) is an in vitro device intended to be used for the measurement of ionized Sodium (Na+), Potassium (K+), and Chloride (Cl-) in serum and lithium heparin venous whole blood samples. The measurements are to be conducted by a trained professional in a clinical laboratory. For in-vitro diagnostic use only. The SelectaLyte Sodium (Na+) assay is intended to measure sodium. Measurements obtained by this device are used to monitor electrolyte balance 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. The SelectaLyte Potassium (K+) assay is intended to measure potassium. Measurements obtained by this device are used to monitor electrolyte balance in the diagnosis and treatment of disease conditions characterized by low or high blood potassium levels. The SelectaLyte Chloride (Cl-) assays is intended to measure chloride. Measurements are used in the diagnosis and treatment of electrolyte and metabolic disorders such as cystic fibrosis and diabetic acidosis.
