Recently we experienced one incident that the patient with A blood type reacted as AB type on macroscopic observation when the blood type was tested immediately after the infusion with Dextran70 in saline. The patient was confirmed as having the A type by reexamination later. Subsequently 90 cases were subjected to blood typing following infusion with one of the seven plasma substitutes such as dextran, MF-gelatin and HE-starch. One patient demonstrated an abnormal reaction. She had marked acceleration of erythrocyte sedimentation rate (E.S.R.) and positive serological reactions for syphilis before the infusion with Dextran70. It was thought that the rapid increase in high molecular colloids in circulation accelerated rouleaux formation and caused the change in agglutination thus resulted in misjudgement of blood typing.
一名A型血患者在生理盐水溶解的右旋糖酐70输注后立即进行血型检测时，肉眼观察血型反应为AB型。该患者后来经复查被确认为A型血。随后，90例患者在输注右旋糖酐、MF-明胶和羟乙基淀粉这七种血浆代用品之一后进行血型鉴定。有一名患者出现了异常反应。她在输注右旋糖酐70之前红细胞沉降率（E.S.R.）显著加快，梅毒血清学反应呈阳性。据认为，循环中高分子胶体的快速增加加速了红细胞缗钱状聚集的形成，并导致凝集反应发生变化，从而造成血型判断错误。
