Lactaat Testen - Veterinary & Racing Animals

 

 


Lactate testing in the veterinary field works in a very similar way to the human application. Lactate measurements are carried out to determine the performance of racing animals like horses or dogs, to monitor organ dysfunction, inflammatory processes in critically ill animals or in a multitude of basic research applications.

The Lactate Scout+ analyzer meets the demands of veterinary use very well. A wide measurement range of 0.5 – 25 mmol/L covers the typical values of different species. E.g. racing horses have a very high “maxlass” (being the highest stable or balanced lactate level during exercise) of above 20 mmol/L, a level at which the Lactate Scout+ still delivers accurate results.

The Lactate Scout+ also compensates for the influence of hematocrit on the lactate reading which can vary for different species and conditions.

The very small sample volume of only 0.2 µl for performing a lactate test makes the device suitable even for repeated testing on small pets, birds or rodents without creating a problem of blood withdrawal.

 

The Accutrend Lactate testing system has been used by veterinarians since 1997 and is currently being used by over 10 veterinary teaching hospitals and 100 emergency veterinarians. Newer portable analyzers, the Lactate Scout and the Lactate Plus will be evaluated for use in veterinary situations in the near future. For example, the Lactate Scout was recently evaluated by veterinarians from the US and the UK.

Abstract - The study was performed to evaluate the accuracy of a portable analyser (Lactate Scout) in measuring canine blood lactate concentrations. First, the effect of sample storage time and temperature on plasma lactate concentrations was evaluated on blood samples obtained from 6 dogs and stored at 48C and 208C. Plasma lactate was measured with a spectrophotometric system (Kone lab) 30, 60, 120, and 240 min after blood collection. The obtained values were compared with the lactate concentration measured immediately after the blood collection. Statistical analysis revealed no significant effects of storage time or temperature. The comparison of lactate values obtained by the portable method with those obtained by the reference analyser (Konelab) was performed on blood samples from 48 dogs. The correlation between methods was r 5 0.98 (sl 5 0.81; int 5 0.20) The level of agreement (Bland Altman) was good for mean concentrations lower than 5 mmol/L. At higher concentrations the Scout analyser values were lower than those measured by the Konelab method, although only 5 of the 48 samples analysed in this study had a lactate result above this value. In summary the Lactate Scout meter exhibits good comparability with the reference Konelab method in the range 0-5 mmol/L.
