背景人类免疫缺陷病毒感染(HIV+)患者血红蛋白(Hb)水平影响直接抗球蛋白实验(DAT)阳性的认识还很不一致。研究设计与方法作者共研究165份来自门诊HIV+病人标本。应用试管检测法和微柱凝聚技术(CAT)进行DAT。结果试管法和CAT检测DAT阳性率分别为18．67％和33．73％。DAT阳性病人的Hb水平比DAT阴性病人低,为12．3 g／dL和14．3 g／dL(P=0．0002)。单变量对数回归可更好地研究这一现象,寻找Hb水平与出现DAT阳性的概率。红细
Background The understanding that hemoglobin (Hb) levels in human immunodeficiency virus-infected (HIV +) patients affect positive for direct antiglobulin experiments (DAT) is still not consistent. Study Design and Methods The authors studied a total of 165 HIV + patient samples from outpatients. DAT was performed using tube test and microcolumn aggregation (CAT). Results The positive rates of DAT by tube and CAT were 18.67% and 33.73% respectively. Hb levels were lower in DAT-positive patients than in DAT-negative patients, at 12.3 g / dL and 14.3 g / dL (P = 0.0002). Univariate logistic regression was better able to study this phenomenon and look for the probability of Hb level and positive DAT. Red fine
