A biochemistry analyzer, also known as a clinical chemistry analyzer or a chemistry analyzer, is a sophisticated instrument used to measure and analyze a wide range of biochemical substances found in biological specimens like blood, urine, cerebrospinal fluid, etc.,
There are two types of Analyzer :
1. Fully Automatic Biochemistry Analyzer
2. Semi Automatic Biochemistry Analyzer
Fully Automatic Biochemistry AnalyzerA fully automatic biochemistry analyzer is a sophisticated laboratory instrument designed to perform a wide range of biochemical tests on blood, urine, and other body fluids with minimal human intervention. These analyzers are equipped with advanced automation features, including sample handling, reagent dispensing, mixing, incubation, and detection, all controlled by a central processing unit.
Semi-automatic biochemistry analyzerA semi-automatic biochemistry analyzer is a lab device that performs biochemical tests with some manual input. It automates processes like reagent dispensing and result calculation, but requires the operator to manually load samples and manage steps like mixing. Ideal for smaller labs, it provides accurate results with a balance of automation and manual control.

A biochemistry analyzer works by measuring the concentration of specific chemicals, metabolites, and proteins in biological samples, such as blood or urine.
The basic working principle involves several steps:
Sample Collection and Preparation: A biological sample (e.g., blood or urine) is collected and prepared for analysis. This may involve dilution or mixing with reagents.
Chemical Reaction: The analyzer adds specific reagents to the sample that cause a chemical reaction with the target substances (e.g., glucose, enzymes, lipids). These reactions often result in color changes, fluorescence, or changes in absorbance.
Optical Detection: The biochemistry analyzer uses light, typically through photometry or spectrophotometry, to measure changes in the sample's optical properties (such as light absorption, reflection, or transmission). The amount of light absorbed is proportional to the concentration of the substance being tested.
Data Processing: The detected signals are processed, and the analyzer calculates the concentration of the target substances based on pre-calibrated data.
Result Output: The results are displayed as numerical values, indicating the concentration of specific analytes (such as glucose, cholesterol, or enzymes) in the sample.
