对手持式便携式乳酸分析仪（KDK）进行了评估，以评定其准确性、可靠性和通用性。在实验室和现场环境下从优秀运动员身上采集毛细血管血样，并进行平行分析。通过与其他三种乳酸分析仪对比来确定准确性：（1）ABL 700系列酸碱分析仪（n = 172例），（2）Accusport乳酸仪（n = 118例），以及（3）YSI 2300 Stat乳酸分析仪（n = 22例）。在1 - 18毫摩尔的范围内确定一致性水平。在相同范围内还确定了两台不同的乳酸分析仪之间结果的重复性。在现场对通用性进行了评估，在一系列室外和室内测试条件下，将乳酸分析仪用于优秀运动员。乳酸分析仪与ABL 700系列酸碱分析仪、YSI 2300和Accusport之间的相关性分别为r = 0.98、r = 0.99、r = 0.97。对同一样本（n = 96例），两台乳酸分析仪之间的相关性为r = 0.99。在1.0 - 18.0毫摩尔的生理范围内，乳酸分析仪与其他分析仪之间的一致性水平通常小于±2.0毫摩尔（平均差值范围：-0.06毫摩尔至0.52毫摩尔）。乳酸分析仪易于操作，在100%的测试中都成功完成了样本分析。总之，乳酸分析仪准确、可靠，与其他乳酸分析仪具有高度的一致性。
An evaluation of the hand-held portable Lactate Pro Analyser (KDK) was undertaken to assess its accuracy, reliability and versatility. Capillary blood samples were drawn from elite athletes in both laboratory and field settings and analysed in parallel. Accuracy was determined in relation to three other lactate analysers: (1) the ABL 700 Series Acid-Base analyser (n = 172 cases), (2) the Accusport Lactate Meter (n = 118 cases), and (3) the YSI 2300 Stat lactate analyser (n = 22 cases). The level of agreement was determined over the range of 1-18 mM. The repeatability of results between two different Lactate Pro analysers was also determined over the same range. Versatility was assessed in the field, where the Lactate Pro was used with elite athletes under a range of outdoor and indoor testing conditions. The correlations between the Lactate Pro and the ABL 700 Series Acid-Base analyser, YSI 2300 and Accusport were r = 0.98, r = 0.99, r = 0.97. The correlation between the two Lactate Pro analysers on the same sample (n = 96 cases) was r = 0.99. The level of agreement between the Lactate Pro and other analysers was generally less than +/- 2.0 mM over the physiological range of 1.0-18.0 mM (range of mean difference: -0.06 mM to 0.52 mM). The Lactate Pro was easy to operate and successfully completed the sample analysis in 100% of the tests performed. In summary, the Lactate Pro is accurate, reliable and exhibits a high degree of agreement with other lactate analysers.
