Fecal Quantitative Human Fecal Occult Blood CLIA Kit

Description

This Chemiluminescence Immunoassay (CLIA) kit is intended for the quantitative determination of human hemoglobin levels in fecesusing the ECL100 or ECL25 Immunoassay analyzer. This assay exclusively measures human hemoglobin without cross-reaction to animal blood.  The test is useful for detecting the severity of gastrointestinal bleeding and in the aid of screening for colorectal adenoma/polyps and cancer, as well as other inflammatory bowel diseases (Crohn’s disease, Ulcerative Colitis, etc.).

Background

This CLIA is designed, developed, and produced for the quantitative measurement of q-FOB level in fecal samples. The assay utilizes a two-site “sandwich” technique with two antibodies that bind to different epitopes of hemoglobin.

Assay calibrators, controls, or patient samples are added directly to a reaction vessel containing streptavidin coated magnetic particles. Simultaneously, anacridinium ester antibody and a biotin antibody are added. The magnetic particles capture the biotin antibody as well as an immuno complex in the form of “magnetic particles – biotin hemoglobin antibody –hemoglobin – acridinium ester hemoglobin antibody”.

​​​​​​​The materials bound to the solid phase are held in a magnetic field while unbound materials are washed away. Then, the trigger solution is added to the reaction vessel and light generated by the reaction is measured with the ECL100 or ECL25 analyzer. The relative light units (RLU) are proportional to the concentration of hemoglobin in the sample. The amount of analyte in the sample is determined from a stored, multipoint calibration curve and reported in serum hemoglobin concentration.
