    Study Notes

    • Automation is revolutionizing laboratory processes, occurring in pre-analytical, analytical, and post-analytical stages.
    • Pneumatic tube systems (PTS) offer rapid specimen transport, but precautions are needed to prevent hemolysis.
    • Barcoding, specifically two-dimensional codes, provide more reliable and efficient specimen identification. Microchips embedded in tubes offer comprehensive sample history tracking.
    • Specimen preparation time is reduced through automated systems, including ion-selective electrodes, which provide rapid electrolyte and other analyte results.
    • Clinical chemistry automation varies by volume and connectivity to larger systems. Analyzers can handle diverse assays, including chemistries, esoteric tests, proteins, therapeutic drugs, and drugs of abuse.
    • Clinical chemistry analyzers often include quality control (QC) systems, which can check multiple parameters for accuracy.
    • Immunoassays, fluoresence immunoassays and chemiluminescence immunoassays (CLIA) are common methods for antibody detection.
    • Molecular diagnostic testing for SARS-CoV-2 (RT-PCR) is the gold standard, utilizing DNA amplification and fluorescence detection.
    • Antigen tests offer rapid results but have lower sensitivity compared to molecular tests and may yield false positives.
    • Urinalysis utilizes both semi- and fully automated systems for chemical and particle analysis. Automated flow cytometry capabilities also exist for analysis of urine sediment or cellular elements.

    Laboratory Measurement and Testing Technologies

    • Genetic testing (diagnostic and predictive) identifies changes in chromosomes, genes, or proteins.
    • Pre-symptomatic, carrier, and prenatal genetic testing options exist.
    • Pharmacogenomics assesses how genetic makeup influences drug response.
    • Nanotechnology allows for miniaturization of laboratory equipment and processes, which is useful for rapid and efficient analysis. Microfluidics and lab-on-a-chip technology reduce sample volumes.
    • Point-of-care testing (POCT) provides rapid results, often in decentralized settings.
    • Home testing kits offer accessibility but may have variances in results compared to lab-based analysis.
    • Automation of laboratory processes significantly reduces labor costs though staffing adjustments in the IT sector may be necessary to manage these processes.
