BS-400 CHEMISTRY ANALYZER, CLC 720 CHEMISTRY ANALYZER
The BS-400/CLC 720 Chemistry Analyzers are designed for clinical laboratory use, making direct quantitative measurements of Na+ (sodium), K+ (potassium), Cl-(chloride) in serum, plasma and urine samples and Glucose in serum samples plasma and urine samples. Additionally, other various chemistry assays may be adaptable to the analyzer depending on the reagent used to induce a photometric reaction.
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.
Glucose measurements are used in the diagnosis and treatment of carbohydrate metabolism disorders including diabetes mellitus, neonatal hypoglycemia, and idiopathic hypoglycemia, and of pancreatic islet cell carcinoma.
The BS-400/CLC 720 Chemistry Analyzer is an automated clinical chemistry analyzer capable of performing various in vitro photometric assays. The Glucose was cleared under K970664 and is the chosen assay to demonstrate performance for the photometric unit. The BS-400 Chemistry Analyzer has an optional lon-Selective Electrode (ISE) module which measures the concentration of the electrolytes, sodium, potassium, and chloride, in samples using ion selective electrode technology.
Here's an analysis of the provided 510(k) summary, extracting the requested information about the device's acceptance criteria and the supporting study:
The document describes the Shenzhen Mindray Bio-medical Electronics Co., LTD BS-400 Chemistry Analyzer (and CLC 720 Chemistry Analyzer, which is stated to be the same model). The device is an automated clinical chemistry analyzer for in vitro diagnostic use, performing photometric assays and having an optional Ion-Selective Electrode (ISE) module.
Summary of Acceptance Criteria and Device Performance:
The primary method for demonstrating performance is through correlation analysis with predicate devices and internal precision, linearity, and limit determination tests. The acceptance criteria are implicitly defined by the reported performance metrics falling within acceptable ranges for clinical diagnostic devices.
