Brief summary
To establish the equivalence of IB10 sphingotest PCT+ measurements in point-of-care settings such as emergency rooms or intensive care units, with corresponding procalcitonin measurements obtained in a reference or clinical laboratory using a comparative assay, with respect to the same subset of human EDTA plasma specimens.
