Serodiagnosis of giardiasis by counterimmunoelectrophoresis assay (CIEP) and indirect immunofluorescence test (IFAT) were evaluated versus stool examination. Giardia lamblia antibodies were detected in sera of 46.9% and 53.1% using CIEP and IFAT respectively out of 49 giardiasis-infected children (5-10 years) diagnosed microscopically. Among the control group (22 children) 13.6% and 18.2% were positive by CIEP and IFAT respectively. The findings of the study showed that we can not rely on serology to diagnose giardiasis specially in cases with low excretion rates.
通过对流免疫电泳分析（CIEP）和间接免疫荧光试验（IFAT）对贾第虫病进行血清学诊断，并与粪便检查进行对比评估。在49名经显微镜诊断为贾第虫病感染的儿童（5 - 10岁）中，分别使用CIEP和IFAT检测到46.9%和53.1%的血清中存在蓝氏贾第鞭毛虫抗体。在对照组（22名儿童）中，CIEP和IFAT检测的阳性率分别为13.6%和18.2%。该研究结果表明，我们不能仅依靠血清学来诊断贾第虫病，特别是在排泄率较低的情况下。
