Giardiasis is one of commonest intestinal protozoa causing diarrheal worldwide especially in daycare
centers. The present study aimed to detect prevalence of G. lamblia and its risk factors among
children by using stained microscopic smears and immunochromatographic test (ICT). A cross-sectional
study was carried out among 100 children (4 to 15 years) suffered from diarrhea at Pediatric Outpatient
Clinics, Aswan University Hospitals. Sheet was filled out one each child or his parents as to
name, sex, age, and previous history of giardiasis. All samples were examined by ICT, and microscopy
The results showed that the prevalence of giardiasis among children was 49%, & 41% by using
stained microscopic examination and rapid ICT (Epituub USA) respectively. Sensitivity and specificity
of rapid test were (77.6% & 94.1%) respectively without cross-reactivity with other parasites, with
potentially useful rapid test in absence of unqualified lab technician or in epidemiologic surveys. Giardiasis
is more prevalent in rural areas' children than in urban ones.
