The blood films both of patients with hereditary pyropoikilocytosis and of those with severe thermal burns are characterised by budding erythrocytes and the presence of microspherocytes. Recently, a fourth example of similar morphological features, caused by overheating of a blood specimen in a motor vehicle during transport to the laboratory, has been observed. It is important to be aware of this artefact as failure to recognise it is likely to lead to diagnostic confusion and unnecessary further testing, causing inconvenience to the patient.
遗传性热异形红细胞增多症患者和严重热烧伤患者的血涂片均以出芽红细胞和小球形红细胞的存在为特征。最近，在将血标本运送到实验室的过程中，因机动车内血标本过热而出现类似形态特征的第四个病例已被观察到。认识到这种人为现象很重要，因为未能识别它可能会导致诊断混乱和不必要的进一步检查，给患者带来不便。
