Microbiology laboratory analyzers designed to test, process, and interpret data from microbiological blood cultures. Blood culture analyzers are available that use a variety of techniques, including detection of carbon dioxide by radiometric or infrared spectrophotometry and detection of microbial activity using photometric or fluorometric measurements; other analyzers use microcalorimetry, pH, electrical impedance, or flow cytometry techniques. Manual analyzers are used in small hospital laboratories; automatic blood culture analyzers are used mainly in laboratories that perform large numbers of tests. Some analyzers can detect microbial growth in body fluids.
