## Indications for Use

The RX Daytona is an automated clinical chemistry analyzer complete with dedicated analyzer software. Software functions of the analyzer include the facility to interact with a host computer for direct download of test method selection details for individual samples. A barcode system is used for the rapid identification of patient samples, reagents and QC samples. The analyzer can be used to run tests including glucose in serum samples. Various other assays are adaptable to the analyzer. Glucose measurements may be used in the diagnosis and treatment of carbohydrate metabolism disorders including diabetes mellitus, neonatal hypoglycemia, idiopathic hypoglycemia and pancreatic islet cell carcinoma. An Ion Selective Electrode (ISE) unit is an optional addition, which may be used with the RX Daytona Analyzer for the measurement of the electrolytes sodium, potassium and chloride in serum, plasma or urine. The ISE unit consists of ion selective electrodes, supply and drain pump, preamplifier board and I/O board. Sodium measurements may be 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. Potassium measurements are used to monitor electrolyte balance in the diagnosis and treatment of diseases characterized by low or high levels of potassium. Chloride measurements are used in the diagnosis and treatment of electrolyte and metabolic disorders such as cystic fibrosis and diabetic acidosis. The RX Daytona analyzer and ISE unit must only be used by suitably qualified personnel, under appropriate laboratory conditions. For in vitro diagnostic use only.

## Device Story

RX Daytona is an automated clinical chemistry analyzer for in vitro diagnostic use in laboratory settings by qualified personnel. It processes serum, plasma, or urine samples using photometric assays and an optional Ion Selective Electrode (ISE) unit. The system utilizes barcode identification for samples and reagents; integrates with host computers for test selection. Photometric unit performs enzymatic assays (e.g., glucose); ISE unit measures sodium, potassium, and chloride via ion electrode potential comparison against a reference electrode. The device provides quantitative results to clinicians for diagnosis and monitoring of metabolic and electrolyte disorders. It includes a QC database for result storage, trend analysis, and Westgard rule application.

## Clinical Evidence

No clinical data provided; substantial equivalence based on technological characteristics and intended use as an automated clinical chemistry analyzer.

## Technological Characteristics
