AUTOANALYZER Meaning and
Definition
-
An autoanalyzer refers to a sophisticated laboratory instrument designed to automate the analysis of biological samples. It is primarily used in clinical chemistry and medical laboratories for high-throughput analysis of various substances present in bodily fluids such as blood, urine, and serum. The term "autoanalyzer" encompasses a wide range of automated systems that employ advanced technologies to determine specific chemical components or analyze biological markers.
This instrument streamlines the process by utilizing computer-controlled mechanisms for sampling, measuring, and interpreting the results. By employing advanced techniques like spectrophotometry, enzymatic assays, or immunoassays, an autoanalyzer efficiently measures the concentration of various analytes like glucose, cholesterol, electrolytes, enzymes, hormones, drugs, and proteins. It can also calculate other relevant parameters such as pH, osmolality, and complete blood count.
The autoanalyzer operates through a series of sequential steps that include sample aspiration, dispensing reagents, incubation, mixing, photometric analysis, and result computation. These systems employ optimized reagent kits, often prepackaged, to analyze multiple samples simultaneously. The automation minimizes human intervention, reducing the potential for errors and improving accuracy, precision, and reproducibility in test results.
The primary advantages of an autoanalyzer are its high sample throughput, improved efficiency, better turnaround time, and reduced labor costs. Furthermore, it offers increased quality control by providing internal and external calibrations to guarantee accurate analysis and reliable results. Overall, autoanalyzers play a pivotal role in diagnostic medicine, enabling clinicians and researchers to obtain valuable information quickly and effectively for disease diagnosis, monitoring, and research purposes.
Etymology of AUTOANALYZER
The word "autoanalyzer" is derived from the combination of two Greek roots: "auto" and "analyzer".
1. The prefix "auto-" comes from the Greek word "autos", meaning "self" or "own". It indicates automation or self-operating capability.
2. The word "analyzer" is derived from the Greek root "analyein", which means "to dissolve, loosen, or untie". It refers to the process of breaking down or examining something in detail.
Thus, when combined, "autoanalyzer" refers to a self-operating device or system that automates the analysis or examination of substances or samples.
