HM-JACKarc uses Integrated Sphere Latex Turbidimetry to measure faecal haemoglobin concentration. The EXTEL HEMO-AUTO HS Latex reagent is composed of consistently sized latex particles. Polyclonal antibodies, specific for human haemoglobin, are bound to the surface of the latex in high concentrations to ensure a very high antigen capture ratio and provide a highly sensitive reagent.
The latex particles have an excess of antibodies to provide a system that will have a hook capacity greater than 200,000ng/ml of haemoglobin (equivalent to 200,000 µg of Hb/g faeces)
