i) Rapid Test

LACTOFERRIN EZ VUE®

The LACTOFERRIN EZ VUE® is an immunochromatographic test for the qualitative detection of elevated levels of lactoferrin, a marker for fecal leukocytes and an indicator of intestinal inflammation. The test can be used as an in vitro diagnostic aid to identify patients with an active inflammatory bowel disease (IBD) and rule out those with active noninflammatory irritable bowel syndrome (IBS).

LEUKO EZ VUE®

The LEUKO EZ VUE® is an immunochromatographic test for the qualitative detection of elevated levels of fecal lactoferrin, a marker for fecal leukocytes and an indicator of intestinal inflammation. The LEUKO EZ VUE® test detects lactoferrin in liquid, semi-liquid, and solid fecal specimens. A positive test result indicates an increased level of fecal lactoferrin and warrants additional testing.

LACTOFERRIN SCAN®

A quantitative ELISA for the detection of fecal lactoferrin.The LACTOFERRIN SCAN® test is a quantitative ELISA for measuring concentrations of fecal lactoferrin, a marker of fecal leukocytes. An elevated level is an indicator of intestinal inflammation. The test can be used as an in vitro diagnostic aid to distinguish patients with active inflammatory bowel disease (IBD) from those with noninflammatory irritable bowel syndrome (IBS). In addition, the test can be used to assess when an IBD patient is in confirmed remission and has responded to treatment.

LACTOFERRIN CHEK®

The LACTOFERRIN CHEK® is an ELISA for the qualitative detection of elevated levels of lactoferrin, a marker for fecal leukocytes and an indicator of intestinal inflammation. The test can be used as an in vitro diagnostic aid to identify patients with active inflammatory bowel disease (IBD) and rule out those with active irritable bowel syndrome (IBS), which is noninflammatory.

ASCA-CHEK™

The ASCA-CHEK™ test is an ELISA for the qualitative detection of human anti-S. cerevisiae antibodies (ASCA) in feces and serum. The test result is used as an aid in the diagnosis of Crohn’s disease in combination with clinical and laboratory findings.The ASCA-CHEK™ test is an enzyme-linked immunoassay (EIA) for detecting ASCA in human feces and serum. The test provides a method utilizing antigens of Saccharomyces cerevisiae for measuring total fecal and serum ASCA as an aid to distinguish Crohn’s disease from other gastrointestinal illnesses such as ulcerative colitis and irritable bowel syndrome.
