Lactate Scout - Accuracy
In 2004 and 2005 the Australian Institute of Sport tested the Lactate Scout versus the Lactate Pro. The test strips for the Lactate Scout during the first test were defective and the test was repeated again in 2005 with new strips.
The defective strips caused the Lactate Scout reading to be high relative to the Lactate Pro. On the second test the Lactate Scout and Lactate Pro provided essentially the same answer.
Here is a comparison of the Lactate Scout and the Lactate Pro readings. Each dot represents an individual reading. The closer to the line, the closer are the two readings.
An analysis of the the Lactate Scout and Lactate Pro by level of lactate reading.
A study was done by Serge von Duvillard of Texas A&M for the 2005 ACSM. Ten subjects completed several stages on a cycle ergometer till exhaustion. Every 3 minutes the power were increased by 30 watts. Seven of the 10 subjects completed 340 watts. Lactate readings were taken by the YSI and the Lactate Scout. The correlation between the two analyzers was 99.3%.

  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.
