What device is commonly used to perform an automated WBC count?

The automated hematology analyzer is the device commonly used to perform an automated white blood cell (WBC) count. This instrument is designed specifically for analyzing blood samples and can quickly and accurately count the number of white blood cells present, among other parameters such as red blood cell counts, hemoglobin levels, and platelet counts.

The reason the automated hematology analyzer is suitable for WBC counting is that it utilizes principles such as impedance or laser-based technology to discriminate between different types of blood cells. This allows for a rapid analysis, which is essential in clinical settings where timely decisions about a patient’s health are necessary.

While a microcentrifuge is useful for separating components of blood for various assays, it does not perform cell counts. A flow cytometer is primarily employed for detailed analysis and sorting of cell populations, mainly in research or specialized clinical diagnostics, rather than just for routine WBC counting. A hemoglobin meter, on the other hand, specifically measures hemoglobin concentration within a blood sample and does not provide a white blood cell count. Therefore, the automated hematology analyzer is the most appropriate device for performing WBC counts in a clinical laboratory setting.
