Which of the following describes the function of the Sysmex XN-1000?

The Sysmex XN-1000 is a sophisticated hematology analyzer that uses advanced technology to provide a comprehensive analysis of blood samples. One of its key functionalities is the detection of forward and side scattered light as well as fluorescence. This capability allows the instrument to analyze various characteristics of blood cells, such as size, granularity, and the presence of specific cellular markers.

Forward scatter primarily provides information about the size of cells, while side scatter gives insight into granularity and complexity. The fluorescence detection enhances its ability to measure specific cell populations or identify abnormal cells based on their unique fluorescence characteristics. This combination makes the Sysmex XN-1000 invaluable in providing a robust assessment of the blood's cellular components, including a detailed white blood cell differential.

While options describing the measurement of cell volume, focusing on granularity, or assessing only portions of blood cell characteristics are somewhat relevant to hematology analysis, they do not encompass the comprehensive capabilities that the Sysmex XN-1000 offers. The correct answer highlights the instrument's advanced methods for evaluating the multifaceted characteristics of blood cells through light and fluorescence detection.
