Brief summary

Anemia prevalence in orthopedic surgery is up to 30 %. Identifying those patients prior to surgery and treating them would be ideal. Different ways of determining hemoglobin Levels are available. In this study classical laboratory determination, determination with HemoCue® and Rad-67™ will be performed to compare precision of those three methods as well as their correlation.
