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.
Additional MDW Patient Case Studies
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 the clinical thought process helped physicians to uncover an underlying infection which 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.
