Clinical Info

Normal: < or = 2.0 mg total hemoglobin/g feces Marginal: 2.1 - 4.0 mg total hemoglobin/g feces* *2.1 - 4.0 mg Hb/g is considered marginally elevated, but not clinically significant, if red meat, warfarin, or aspirin was ingested 72 hrs prior to collection. Elevated: > 4.0 mg total hemoglobin/g feces HemoQuant detects blood in feces and is the most appropriate fecal occult blood test to use in the evaluation of iron deficiency. Other useful applications include the detection of bleeding as a complication of anticoagulant therapy and other medication regimens. This test detects both intact heme and porphyrins from partly degraded heme. Additionally, test results are not complicated by either the water content of the specimen or the presence of reducing or oxidizing substances. Furthermore, HemoQuant testing is sensitive to both proximal and distal sources of occult GI bleeding.
