Specimen hemolysis is a frequent finding when blood is collected from neonates. This produces artificially high results for some analytes, such as potassium. Testing samples for electrolytes using point-of-care (POC) blood gas analyzers is convenient and facile. However, unlike testing that is conducted on serum or plasma from a central laboratory, detection of hemolysis using POC analyzers cannot currently be achieved. As described in these cases, the presence of hemolysis can produce ambiguities and delays in the diagnosis and management of neonates.
新生儿采血时,样本溶血是常见现象。这会导致某些分析物(如钾)的检测结果人为偏高。使用即时检验(POC)血气分析仪检测电解质样本既方便又快捷。然而,与在中心实验室对血清或血浆进行的检测不同,目前使用POC分析仪无法检测到溶血情况。如这些病例所述,溶血的存在会在新生儿的诊断和治疗中造成混淆并导致延误。
