Serodiagnosis of giardiasis by counterimmunoelectrophoresis and indirect immunofluorescence tests

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
