ABSTRACT
BACKGROUND: Fecal occult blood tests (FOBT) have been recommended for gastro- intestinal bleeding and colon cancer screening. This study compared the effectiveness of two fecal blood screening kit, OC-Hemodia II and Ez step FOB for fecal occult blood. METHODS: The detection limit was evaluated by using OC-control and serially diluted samples. The comparison study between OC-hemodia II and Ez step FOB were evaluated in 143 cases. RESULTS: The concordance rate between OC-Hemodia II and Ez step FOB was 85.6% and 50% of non-concordance cases have history related to gatrointestinal bleeding. Ez step FOB was possible to detect 35 ng/mL in serially diluted OC-control. CONCLUSIONS: The result of Ez step FOB satisfactory to clinical application and showed good concordance rate compared to OC-Hemodia II.
