title: Comparison in the performance of glucose meters in blood glucose monitoring during pregnancy.
abstract: OBJECTIVE
  To compare the performance of the four latest models of glucose meters in capillary blood glucose monitoring during pregnancy.
  
  
  METHODS
  208 pregnant women with gestational diabetes were recruited. Each subject had simultaneous capillary glucose monitoring by two study glucose meters and venous plasma glucose assay. The performance of four glucose meters was compared using error grid analysis (EGA) and the agreement between the meter readings and plasma glucose by Bland-Altman plot analysis.
  
  
  RESULTS
  Elite, Advantage II and CareSens had more than 90% of readings in the acceptable target range of EGA. CareSens had the lowest mean bias by Bland-Altman analysis while Advantage II had the highest proportion of readings within 5% difference from plasma glucose. Readings from all glucose meters except Optium were not influenced by the change in maternal hematocrit levels.
  
  
  CONCLUSIONS
  The performance of four study glucose meters appeared very similar.
