Hematology Analyzers are commonly used in clinical labs to characterize blood cell numbers and types -- essential in disease diagnostics and health monitoring. Analyzers can range from basic instruments for complete blood count (CBC) to multifunctional systems designed for cell morphology and measurement of distinct cell populations. Systems are based around several technologies including impedance-based measurement, flow cytometry, and fluorescence associated flow cytometry, among others. Important considerations include the signal source and detectors, as well as the robustness of the analysis chamber(s). Scale of use is also an important consideration.
