title: Alternative sampling site for blood glucose testing in cats: giving the ears a rest.
abstract: BACKGROUND AND STUDY RATIONALE: Home monitoring is an important part of the long-term management of diabetic cats. Despite the extensive use of glucometers in this species, up until now only the pinna of the ear has been validated as a testing site. This cross-sectional study investigated the feasibility and validity of sampling from the metacarpal/metatarsal pads in hospitalised cats with various diseases.
  
  
  METHODS
  The large pads were compared with the ear as a sampling site in 75 cats. Lancing the pads was tolerated very well. If the initial drop of blood was too small, an adequate volume of blood was almost always achieved by squeezing the pads. No significant differences were observed in first-attempt success rate or glucose values between the two sites. Due to the inability to obtain an adequate volume of blood or struggling, no measurement was possible in four cats.
  
  
  BACKGROUND
  While further work is necessary to assess the utility of this technique, especially in the home environment, the results indicate that the metacarpal pads, in particular, may offer a viable alternative testing site for the measurement of blood glucose concentrations, especially if ear sampling fails.
