Detect Sepsis Earlier

Diagnostic uncertainty is a major challenge for patients presenting to emergency department (ED) with low number of signs and symptoms. What if there was a way to aid emergency departments in early sepsis detection?

Hematology-based Cellular Biomarker in the Emergency Department

Monocyte Distribution Width (MDW) is a measure of increased morphological variability of monocytes in response to bacterial, viral or fungal infections. The quantitative analysis of MDW has received regulatory clearance to help emergency department physicians identify patients with severe infection leading to sepsis.

Considered with other signs and symptoms, the value of MDW helps differentiate sepsis from non-septic presentations, including non-infectious systemic inflammatory response.4 This parameter is automatically reported with the complete blood count (CBC) with differential on the DxH 900 and DxH 690T hematology analyzers*, enabling automatic reporting without added workload burden. 

 

Key Findings from Journal of Intensive Care Study  The performance of MDW for sepsis detection has been evaluated in the prospective observational study of 2,158 emergency department patients in three large academic centers.

Diagnostic Performance for Sepsis Detection



Considering MDW together with WBC, MDW may add to the sensitivity and specificity of sepsis detection, as part of the standard assessment protocol in the emergency department.4,5

MDW in Patients with "Gray Zone" Symptoms

Diagnostic uncertainty is a major challenge for patients presenting to the emergency department with a low number of signs and symptoms.

MDW Modulates the Probability of Sepsis

When considered with the standard physiologic parameters at the time of patient presentation, abnormal values of MDW signify a 4-6x increase in probability of sepsis diagnosis.

T-47 Minutes to Antibiotics Administration

MDW biomarker identified a risk of severe infection and reclassified the patient into higher acuity category, in conjunction with current standard of care.

Abnormal MDW 27.3 Changed Patient’s Trajectory

The inclusion of monocyte distribution width (MDW) biomarker in clinical thought process helped physicians to uncover an underlying infection, that could have otherwise been missed, leading to inappropriate therapeutic interventions. We can prevent sepsis by preventing evolution of infection to sepsis.

The value of MDW is that it provides physicians with an earlier indication of sepsis during the initial encounter, which is especially important when a patient’s symptoms are mild and alternative diagnosis are being considered.
