背景 微量柱技术已用于血清学调查,然而由于其较高的 灵敏度,显而易见会产生假阳性,例如在高丙种球蛋白血症中应用。本研究的目的是评价微量技术在多发性骨髓瘤患者中应用效果。 方法 对80例多发性骨髓瘤患者采用微量柱法和传统的试管法进行输血前检测。结果 在微量柱间接抗球蛋白试验和酶试验中全部血清为阴性,而该酶试管法中58％样品为阳性。在微量柱直接抗球蛋白试验中约40％样品为阳性,但试管法中
Background Micro-column technology has been used for serological investigations, but due to its high sensitivity, false positives are apparent, such as in hypergammaglobulinemia. The purpose of this study was to evaluate the application of microtechnology in patients with multiple myeloma. Methods A total of 80 patients with multiple myeloma were examined by pre-transfusion method using the microcolumn method and the traditional tube method. Results All sera were negative in the micro column indirect antiglobulin and enzyme assays, and 58% of the samples in the enzyme tube assay were positive. About 40% of samples in the micro column direct antiglobulin test are positive, but in the test tube method
