This document discusses automation in biochemistry laboratory testing. It defines automation as using instruments to perform tests with minimal human involvement. There are different phases and types of analyzers used in automation. Continuous flow analyzers and discrete autoanalyzers are described in detail. The document also discusses specific automated machines used in the author's laboratory, including their main components and functions. Benefits of automation include higher throughput, reduced errors and variability, lower sample/reagent use, and labor savings, though automation has high initial costs.
