Detect Sepsis Earlier, and Act with More Confidence

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

Sepsis Detection Using Monocyte Distribution Width

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 clearances as an aid for early detection in adult patients with or developing sepsis in emergency departments.

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 sepsis biomarker is automatically reported with the complete blood count (CBC) with differential* for adult emergency department patients, without any additional test ordering.


Monocyte distribution width

Increased Sensitivity

Sensitivity of technologies is critical. When considered alone, the discriminating power of MDW is similar to that of White Blood-cell Count (WBC).

However, when MDW is considered 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

The Challenge of Low Symptom Presentation

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

  • 60% of emergency department patients who were diagnosed with sepsis in a pivotal study presented with zero or one symptom used for sepsis screening
  • Abnormal MDW was present in up to 70% of septic "gray zone" patients4,5

MDW Modulates the Probability of Sepsis

Considered with other parameters, abnormal MDW at presentation increases the odds of sepsis.

The study determined that, when considered along 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. In patients with a low level of symptoms and highest diagnostic uncertainty at presentation, abnormal MDW increased the odds of sepsis by ~3x.6

MDW Adds Value to Sepsis Detection

Novel protocols and biomarkers are being studied to improve sepsis detection time. A clinical study evaluates the diagnostic accuracy of MDW for early sepsis detection.

Find out how MDW can aid emergency department physicians in sepsis-related clinical decision-making by measuring morphological changes in monocytes.

BARDA Funding to Aid in Early Sepsis Detection

Beckman Coulter receives BARDA funding to develop a next-generation analytic algorithm to predict and detect sepsis earlier, with the goal of reducing sepsis mortality rates through earlier intervention.

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.
