The Near-Patient Testing Instrument HemoScreen can be used for Rapid Evaluation of Peripheral Blood Cell Counts in Patients with COVID-19

• Objectives: Analysis of peripheral blood cell counts are important in the workup of patients with suspected Corona virus disease 2019 (COVID-19). Blood cell counts are usually analyzed on large cell counters that require transport of the samples. Point-of-care (POC) testing reduces the test-turnaround times. The aim of the present study was to evaluate if the HemoScreen™instrument could be used for point of care testing of blood samples from COVID-19 patients. Methods: We compared CBC results from 49 patients with COVID-19 infections analyzed with HemoScreen™ and Sysmex XN-9000. Results: There were strong correlations between the results obtained with Sysmex XN-9000 and HemoScreen™ according to Deming correlations for White Blood Cells (WBC): WBCHemoScreen™ = 0.944* WBCSysmex - 0.093; r2 = 0.988, Neutrophils: NeutrophilsHemoScreen™= 1.029* NeutrophilsSysmex + 0.090; r2 = 0.957, Lymphocytes: LymphocytesHemoScreen™ = 0.944* LymphocytesSysmex - 0.107; r2 = 0.964, Platelets (PLT): PLTHemoScreen™ = 1.056* PLTSysmex + 9.468; r2 = 0.988, and Red blood cells (RBC) RBCHemoScreen™ = 0.955* RBCSysmex - 0.003; r2 = 0.991. Conclusions: The HemoScreen™ instrument provided fast and accurate test results when analyzing blood samples from COVID-19 patients. This instrument can be used in settings where the transport time to the central laboratory from remote locations such as field hospitals can be long.
