Feasibility Study of Hematology Parameters in COVID-19 Disease

5. december 2021 opdateret af: Beckman Coulter, Inc.

Feasibility Study to Evaluate Performance of MDW and Other Hematology Parameters for Identification of COVID-19 Disease and Clinical Progression in Adult Hospitalized Patients - Washington University

The purpose of this study is to evaluate the potential for MDW and other CPD parameters (measured with CBC-DIFF) to identify COVID-19 diseased adult individuals presenting to the hospital with symptoms suggestive of COVID-19 or respiratory infection and whose standard of care includes CBC-DIFF and microbial testing.

Detaljeret beskrivelse

The objective of this study is to evaluate MDW and/or combination(s) of hematology parameters that best identify patients with COVID-19 disease who tested SAR-CoV-2 positive by standard of care (SOC) COVID-19 testing.

A feasibility study of consecutive adult patients who presented to the hospital with symptoms suggestive of COVID-19 or respiratory infection and whose standard of care testing involves a CBC-DIFF and microbial testing including RT-PCR testing for SARS-CoV-2 will be enrolled. This study will evaluate MDW and other CPD parameters performance in COVID-19 patients and the ability of MDW to identify RT-PCR positive COVID-19 patients as well as potential added value to RT-PCR tests of MDW. A minimum of 50 COVID-19 positive and 150 COVID-19 negative patients meeting inclusion criteria will be evaluated. Patients with symptoms suggestive of COVID-19 and who have RT-PCR test samples drawn will be retested on the DxH900 hematology analyzer to capture baseline MDW results. In addition, a retrospective data extraction will be performed for those patient samples tested during the Post Market study during the COVID-19 pandemic that meet the revised study population.
