Clinical Trial Summary

In patients with symptoms of infection, tissue injury and inflammatory disorders the study will evaluate agreement between the CRP measurements from the LumiraDx POC CRP assay and the Siemens Dimension Xpand Plus CRP assay, as an aid in evaluation and detection of infection, tissue injury and inflammatory disorders.

Clinical Trial Description

This is a performance evaluation study designed to assess the precision and accuracy of the LumiraDx point of Care (POC) C-reactive Protein (CRP) test when used in patients presenting with symptoms of infection, tissue injury or inflammatory disorder. The LumiraDx POC CRP test is a quantitative immunoassay providing results in under 10 minutes. The accuracy of the LumiraDx POC CRP test will be assessed using capillary whole blood, venous blood, and plasma samples, by comparison to the CRP results obtained from the same individuals as analysed by trained laboratory professionals using the reference device, Siemens Dimension Xpand Plus CRP assay. The results of this study are intended to be used for regulatory filings for use as an in vitro diagnostic test in the UK, European Union (EU) and other relevant geographies. Adults (aged 18 and over at time of consent) presenting to the study sites with symptoms of infection, tissue injury or inflammatory disorder will be included in the study. Approximately 250 patients will be recruited to ensure that sufficient suitable patients are enrolled and to allow for a small level of exclusions. After obtaining informed consent, blood tube samples will be drawn and fingerstick samples of capillary blood will be taken from the subject, these will be applied directly onto unique test strips for immediate measurement of CRP on the LumiraDx POC instrument. The CRP results obtained via the LumiraDx CRP test will be used in a set of comparative analyses designed to determine the performance characteristics of the test. This study is an observational, cross-sectional design. As an observational study of an investigative device, results obtained during the course of the study will not inform or alter patient management or treatment decisions in any way. ;
