Biological Variation Of Thromboelastography Variables In Ten Healthy Female Horses, Jennifer Lee Scruggs

Masters Theses

Biological variability (BV) has important applications in laboratory medicine. It can be a source of variation in measured analyte values and provide guidance on reference interval use. BV has three components: between-individual variation (CVg), caused by differences in mean values of a particular analyte among members of a group, within-individual variation (CVi), caused by fluctuations around an individual’s inherent homeostatic set point, and analytical variation (CVa). Thromboelastography (TEG), a type of viscoelastic coagulation analysis, is becoming increasingly common in veterinary referral centers. Despite increased popularity, the optimal method of results interpretation is not clear. While population-based reference intervals (PRI) are …
