Ensuring Clinical Excellence: The Mindray SAL9000 Biochemical Immunoassay System.

Area of Science:

• Clinical Laboratory Science
• Biomedical Engineering
• Analytical Chemistry

Background:

• The Mindray SAL9000 is an integrated biochemical and immunoassay automation system.
• Clinical laboratories require validated systems for accurate diagnostic testing.
• ISO 15189 standards mandate rigorous performance verification for laboratory equipment.

Purpose of the Study:

• To evaluate the performance and clinical laboratory adaptability of the Mindray SAL9000.
• To ensure the system's compliance with ISO 15189 and national requirements.
• To assess the system's suitability for outpatient and emergency laboratory settings.

Main Methods:

• Comprehensive performance verification of 21 biochemical and 15 immunoassay analytes.
• Assessed parameters included precision, accuracy, linearity, measurement range, interference, and inter-instrument comparison.
• Validated against established standards and compared with existing systems (BS2000M, Roche 702).

Main Results:

• The Mindray SAL9000 demonstrated high precision and accuracy across tested analytes.
• Good linearity and minimal bias were observed for most analytes.
• The system showed excellent resistance to common interferences (hemolysis, ascorbic acid, jaundice) but was affected by specific substances.
• Inter-instrument comparisons showed good correlation, with minor biases for ALT and AST.

Conclusions:

• The Mindray SAL9000 meets clinical laboratory requirements for precision, accuracy, and measurement range.
• The system is a reliable and adaptable automation solution for clinical settings.
• Its performance validates its suitability for high-throughput outpatient and emergency laboratories.
