title: Reference intervals for mean platelet volume and immature platelet fraction determined on a sysmex XE5000 hematology analyzer.
abstract: BACKGROUND
  New parameters describing the platelet population of the blood are mean platelet volume (MPV), which is a crude estimate of thrombocyte reactivity, and immature platelet fraction (IPF), which reflects megakaryopoietic activity. This study aimed to define reference intervals for MPV and IPF and to investigate whether separate reference intervals according to smoking status, age or sex are necessary.
  
  
  METHODS
  Blood samples were obtained from subjects participating in The Danish General Suburban Population Study. MPV and IPF measurements were performed by the use of the Sysmex XE-5000 hematology analyzer. Reference intervals were established by a non-parametric method.
  
  
  RESULTS
  In total, 1674 apparently healthy individuals (910 females and 764 males) were included. No significant age, sex or smoking status difference was observed. The reference interval was 9.6-13.1 fL for MPV and 1.3-9.0% for IPF, respectively.
  
  
  CONCLUSIONS
  We have generated reference intervals for MPV and IPF in a large, adult Danish population and found those parameters remarkably stable across age, sex and smoking status.
