Differential counts of white blood cell (WBC) populations, included in thecomplete blood count (CBC), are essential in assessing overall health and monitoring patients.

There are two main types of differential WBC analyzers: 3-population and 5-population, which differ mainly in their ability to identify and count WBC subtypes.

The 3-population analyzers use impedance measurements to differentiate between lymphocytes, monocytes and granulocytes, which are suitable for basic screening and routine checks. However, they are less accurate than 5-population analyzers.

The advantages of 5-population differential counts: In addition to impedance measurements, they employ flow cytometry for more in-depth analysis, identifying five subtypes of WBCs: neutrophils, lymphocytes, monocytes, eosinophils and basophils. This advanced technology is crucial for accurate diagnoses in areas such as oncology, hematology and immunology, where accurate typing of WBCs is critical.

PixCell Medical's HemoScreen stands out as the only 5-population analyzer approved for point-of-care testing ( POCT) use, providing laboratory-quality results in just five minutes. Operating with disposable cartridges, eliminating the need for reagents, this device combines the speed and convenience of 3-population analyzers with the advanced accuracy of 5-population analyzers. HemoScreen is fully automated and requires no calibration or maintenance, thus minimizing operational and ownership costs.

In conclusion, PixCell Medical's HemoScreen transforms blood testing into POCT, enabling health professionals to perform complex blood tests with rapid results, facilitating diagnosis and treatment of patients with an efficient and accurate method.
