The Biolis 12i is a discrete photometric chemistry analyzer with ion-selective electrode (ISE), with direct quantitative measurement of sodium, potassium, chloride, and glucose in serum. It is a device intended for the in-vitro, spectrophotometric determination of general chemistry assays for clinical use. The Biolis 12i includes an optional Ion Selective Electrode (ISE) module for the measurement of sodium, potassium and chloride in serum. The Biolis 12i is not for Point-Of-Care testing: It is for vitro diagnostic use only.

Sodium measurements are used in the diagnosis and treatment diseases involving electrolyte imbalance.

Potassium measurements monitor electrolyte balance and in the diagnosis and treatment of diseases conditions characterized by low or high blood potassium levels.

Chloride measurements are used in the diagnosis and treatment of electrolyte and metabolic disorders.

The Biolis 12i analyzer with glucose hexokinase assay is intended to measure glucose quantitatively in human serum. Glucose measurements are used in the diagnosis and treatment of carbohydrate metabolism disorders including diabetes mellitus, neonatal hypoglycemnia, and idiopathic glycemia, and of the pancreatic islet cell carcinoma.

Indications for use as stated in the FDA summary.
