## Indications for use
The SMARTLYTE is an automated, microprocessor-controlled analyzer which utilizes ion-selective electrodes for the measurement of sodium, potassium, chloride, calcium and lithium in serum, plasma, whole blood, pre-diluted urine samples. In addition, the analyzer can also measure sodium, potassium, chloride and calcium in dialysate samples. The SMARTLYTE Sodium Assay is intended to measure sodium in whole blood, serum, plasma, pre-diluted urine and dialysate on the SMARTLYTE Electrolyte Analyzer. Measurements obtained by this device are used to monitor electrolyte balance in the diagnosis and treatment of aldosteronism (excessive secretion of the hormone aldosterone), diabetes insipidus (chronic excretion of large amounts of dilute urine, accompanied by extreme thirst), adrenal hypertension, Addison's disease (caused by destruction of the adrenal glands), dehydration, inappropriate antidiuretic hormone secretion, or other diseases involving electrolyte imbalance. The SMARTLYTE Potassium Assay is intended to measure potassium in whole blood, serum, plasma, urine and dialysate. Measurements obtained by this device are used to monitor electrolyte balance in the diagnosis and treatment of diseases conditions characterized by low or high blood potassium levels. The SMARTLYTE Chloride Assay is intended to measure the level of chloride in whole blood, serum, plasma, urine and dialysate. Chloride measurements are used in the diagnosis and treatment of electrolyte and metabolic disorders such as cystic fibrosis and diabetic acidosis. The SMARTLYTE Calcium Assay is intended to measure ionized calcium levels in whole blood, plasma, serum, and diatysate. Calcium measurements are used in the diagnosis and treatment of parathyroid disease, a variety of bone diseases, chronic renal disease and tetany (intermittent muscular contractions or spasms). The SMARTLYTE Lithium Assay is intended to measure lithium (froth the drug lithium carbonate) in whole blood, plasma, and serum. Measurements of lithium are used to assure that the proper drug dosage is administered in the treatment of patients with mental disturbances, such as manic-depressive illness (bipolar disorder).
