title: Temperature variations within and between incubators-a prospective, observational study.
abstract: OBJECTIVE
  To determine if there is a temperature variation within and between incubators.
  
  
  METHODS
  This prospective, experimental trial with external controls was performed at an Assisted Reproductive Technology laboratory in a tertiary-care, university hospital. Temperature values were taken at various locations within and between incubators.
  
  
  RESULTS
  Even though they were both set to 37.0 °C, the same make and model incubators had significantly different internal temperatures. Temperatures differed significantly among top, middle and bottom shelves and between fronts and backs of shelves.
  
  
  CONCLUSIONS
  We found temperatures differed within and between our front-loading incubators. Thus, laboratory personnel should evaluate their incubators for temperature variations within and between incubators and, if temperatures differ significantly, develop a plan to deal with discrepancies.
