When comparing prices, you must distinguish between 3-part and 5-part differential models. 5-part analyzers (like the XN series) command a higher price due to their ability to identify neutrophils, lymphocytes, monocytes, eosinophils, and basophils, providing deeper clinical insight. Additionally, check the throughput capacity (e.g., 60 to 100 samples per hour) and whether the unit includes automated sampling (Autoloader) versus manual aspiration, as these features significantly impact the capital expenditure.
