Blood gas testing is a commonly ordered test in hospital settings, where the results almost always have the potential to dictate an immediate or urgent response. The preanalytical steps in testing, from choosing the correct tests to ensuring the specimen is introduced into the instrument correctly, must be perfectly coordinated to ensure that the patient receives appropriate and timely therapy in response to the analytical results. While many of the preanalytical steps in blood gas testing are common to all laboratory tests, such as accurate specimen labeling, some are unique to this testing because of the physicochemical properties of the analytes being measured. The common sources of preanalytical variation in blood gas testing are reviewed here.
血气检测是医院环境中常用的检测项目，其结果几乎总能决定即刻或紧急的应对措施。检测的分析前步骤，从选择正确的检测项目到确保标本正确地引入仪器，必须完美协调，以确保患者根据分析结果得到适当和及时的治疗。虽然血气检测的许多分析前步骤与所有实验室检测都相同，例如准确的标本标记，但由于所测量分析物的物理化学性质，有些步骤是该检测所特有的。本文回顾了血气检测中常见的分析前变异源。
