If, as is often the case in routine practice, the gasometric analysis cannot be conducted immediately after withdrawal of the blood specimen, this does not have important consequences for the clinical. When the blood specimens are stored in open glass tubes, the alterations are all within the demands made of the method for measurement accuracy. As far as the purely clinical problem is concerned, it would even be possible to let the umbilical cord itself set for up to 90 minutes. Discrepancies between the gas status from blood specimens measured late and the Apgar score cannot be explained by storing and, insofar as errors in measurement are not involved, can represent an important piece of informations for the diagnosis of the condition of the newborn.
在常规实践中，情况常常如此，即血液标本采集后无法立即进行气体分析，这对临床而言并无重要影响。当血液标本储存在开口玻璃管中时，各项变化均在测量方法的精度要求范围内。就纯粹的临床问题而言，甚至可以让脐带血静置长达90分钟。晚期测量的血液标本气体状态与阿氏评分之间的差异无法用储存来解释，并且在不涉及测量误差的情况下，可为新生儿状况的诊断提供重要信息。
