To compare, for blood samples from dogs and horses, blood electrolyte concentrations, blood gas partial pressures, and Hct obtained using a handheld analyzer with those obtained using a standard chemistry analyzer and to compare results obtained with the handheld analyzer using warm versus cold test cartridges.
Case series with analysis of split samples.
Blood samples from 22 dogs and 17 horses.
Sodium, potassium, ionized calcium, bicarbonate, and total CO2 concentrations, pH, PO2, PCO2, base excess, and Hct were determined by use of a handheld analyzer and test cartridges that had been allowed to warm to ambient temperature or had been recently removed from a refrigerator. Results were compared with those from a standard chemistry analyzer by use of linear regression.
For canine samples, values obtained with the handheld analyzer and warm cartridges were highly correlated (r2 > or = 0.83) with values obtained with the standard chemistry analyzer, except for sodium concentration (r2 = 0.6). For equine samples, values obtained with the handheld analyzer and warm cartridges were highly correlated (r2 > or = 0.79) with values obtained with the standard chemistry analyzer, except for Hct (r2 = 0.38). For all samples, results obtained with cold and warm cartridges were moderately correlated (r2 > or = 0.69).
Results obtained with the handheld analyzer were similar to those obtained from the standard chemistry analyzer, with the exception of sodium concentration for canine samples and Hct for equine samples. Results were not substantially affected by use of cold, rather than warm, test cartridges.
比较犬和马的血液样本，使用手持式分析仪获得的血液电解质浓度、血气分压和血细胞比容（Hct）与使用标准化学分析仪获得的结果，并比较使用温热与冷藏测试盒的手持式分析仪所获得的结果。
对分割样本进行分析的病例系列。
22只犬和17匹马的血液样本。
使用已升温至室温或刚从冰箱中取出的手持式分析仪和测试盒，测定钠、钾、离子钙、碳酸氢盐和总二氧化碳浓度、pH、PO₂、PCO₂、碱剩余和Hct。通过线性回归将结果与标准化学分析仪的结果进行比较。
对于犬类样本，除钠浓度外（r² = 0.6），使用手持式分析仪和温热测试盒获得的值与使用标准化学分析仪获得的值高度相关（r²≥0.83）。对于马类样本，除Hct外（r² = 0.38），使用手持式分析仪和温热测试盒获得的值与使用标准化学分析仪获得的值高度相关（r²≥0.79）。对于所有样本，使用冷藏和温热测试盒获得的结果中度相关（r²≥0.69）。
手持式分析仪获得的结果与标准化学分析仪获得的结果相似，但犬类样本的钠浓度和马类样本的Hct除外。使用冷藏而非温热测试盒对结果没有实质性影响。
