Monocyte distribution width (MDW) is a cytometry-based parameter that measures the range of variation of monocytes. If the parameter is available, it is reported as part of the standard complete blood count (CBC) with differential.[1]
The parameter was FDA cleared as an early sepsis indicator for ER patients in 2019 for Beckman Coulter.[2][3]
MDW serves as an indicator for early screening of sepsis in conjunction with CRP and PCT and for differentiating false positive blood cultures.[4][5]
