Evaluation of a portable lactate analyzer (Lactate Scout) in dogs

Abstract

The Lactate-Scout analyzer is reliably comparable to a reference method for measuring whole blood lactate concentration in dogs; however, caution should be used when interpreting lactate values of 5 mmol/L and higher.

Reliability of Lactate Scout Portable Analyzer in Agility Dogs During Multiple Measurements

“…Moreover, there was a positive and signifi cant correlation between these methods. Some studies appeal to caution when interpreting higher lactate values (>5 mmol/L) with the Lactate Scout analyzer [2,9]. In our study, the maximum concentration was below that value (2.6 mmol/L) and therefore we consider our results to be reliable.…”

“…There are many studies on the evaluation of portable lactate analyzers in human and veterinary sports medicine but most of them were undertaken to assess the accuracy and reliability of the Lactate Pro analyzer or some other hand held lactate analyzers beside Lactate Scout analyzer [2,9,12,14,15]. However, all the mentioned studies were conducted during rest i.e.…”

“…For the same reason blood lactate concentration is measured in sports animals, mostly dogs and horses [4][5][6][7]. Since lactate concentration correlates with the total oxygen debt, the magnitude of hypoperfusion and the severity of shock, it is also used to assess the seriousness and prognosis of several medical and surgical critical conditions [8][9][10].…”

Comparison of canine capillary and jugular venous blood lactate concentrations determined by use of an enzymatic-amperometric bedside system

“…In the present study, a suitable blood sample was obtained from approximately 90% of the dogs by use of a non-vacuum-assisted lancing device, and it is possible that a higher number of samples suitable for analysis may have been obtained by use of a vacuum-action lancing device. Although a preliminary assessment of interoperator variability was not performed prior to the present study, the low coefficient of variation of lactate values measured by the portable lactate analyzer, both at low and high lactate concentrations, 8 would suggest that the lack of agreement between venous and capillary technique was not caused by analytic variability. 11 However, this procedure was deliberately omitted in our study to prevent possible distress in the dogs and avoid potential changes in tissue oxygen delivery and, consequently, changes in local lactate production.…”
