Abstract:
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.
