OBJECTIVE
The purpose of this study was to determine if there was agreement between a new point-of-care (POC) lactate analyzer and a handheld laboratory analyzer when measuring blood lactate concentration in cats.
DESIGN
Prospective observational study.
SETTING
University veterinary teaching hospital.
ANIMALS
Fifty-four cats that presented to an emergency service.
INTERVENTIONS
None.
MEASUREMENTS AND MAIN RESULTS
Lactate concentrations as measured by the handheld laboratory analyzer ranged from 0.3 to 15.4 mmol/L. Agreement analysis of the handheld laboratory analyzer and the POC lactate meter demonstrated a bias, -0.06 and limits of agreement ranging from -0.87 to 0.99 mmol/L. Regression analysis demonstrated a coefficient of determination (R ) of 0.98.
CONCLUSION
Results of the present study indicate that the POC lactate meter provided results that are in agreement with a handheld laboratory analyzer when measuring lactate in clinically ill patients.
目的
本研究旨在确定一种新型即时检测（POC）乳酸分析仪与手持式实验室分析仪在测量猫血乳酸浓度时是否具有一致性。
设计
前瞻性观察性研究。
地点
大学兽医教学医院。
动物
54只就诊于急诊服务部门的猫。
干预措施
无。
测量与主要结果
手持式实验室分析仪测得的乳酸浓度范围为0.3至15.4 mmol/L。手持式实验室分析仪与POC乳酸计的一致性分析显示偏差为-0.06，一致性界限为-0.87至0.99 mmol/L。回归分析显示决定系数（R）为0.98。
结论
本研究结果表明，POC乳酸计在测量临床患病动物的乳酸时，其结果与手持式实验室分析仪一致。
