【摘要】 为了研究初筛为RhD(-)样本中弱D及Del的检测,采用常规血清学方法初筛RhD,用间接抗人球蛋白试验(IAT)检测弱D,应用三氯甲烷/三氯乙烯吸收放散法检测Del。结果表明:在26200例献血者中,常规血清学初筛D(-)者56例(2.14‰),其中经IAT实验确认为弱D型者5例,吸收放散试验确认Del型者9例,且与CE表型相关。结论:为了临床输血安全,经常规血清学检测RhD阴性者,应当再用间接抗球蛋白试验及吸收放散实验检测是否为弱D及Del。更多还原

【Abstract】 To study the detection of weak D and Del from samples initially screened RhD(-), RhD phenotype was initially screened by routine serological test, out of which weak D phenotype was detected by indirect antiglobulin test(IAT)and Del phenotype was detected by chloroform-trichloroethylene absorption-elution test. The results showed that 56 samples were RhD(-) confirmed by routine serology test, which were screened out of 26 200 donors, among them 5 samples were typed as weak D by IAT and 9 cases samples were typed as Del by absorption-elution test. In conclusion, the samples which typed as RhD(-) by routine serological test must be identified by IAT and chloroform-trchloroethylene absorption test is order to detect weak D and Del phenotype. It is important for clinical transfusion safely.更多还原
