Hematology analyzers (also spelled haematology analysers in British English) are used to count and identify blood cells at high speed with accuracy.
[4] Hematology analyzers are used to conduct a complete blood count (CBC), which is usually the first test requested by physicians to determine a patient's general health status.
The 3-part analyzer is able to differentiate between three types of white blood cells (WBCs): neutrophils, lymphocytes, and monocytes.
[7] This type of hematology analyzer utilizes both Coulter's principle and flow cytometry to determine the granularity, diameter, and inner complexity of the cells.
[8] A 5-part cell counter can differentiate all WBC types (neutrophils, lymphocytes, basophils, eosinophils, and monocytes).
