Qualitative Faecal Hb (FHb)

Qualitative Faecal Hb (FHb)

Purpose:
The Qualitative Faecal Hb programme is available as part of a comprehensive suite of programmes to assess and monitor the performance of the Clinical Biochemistry laboratory’s repertoire of both core and esoteric tests used for the diagnosis and monitoring of disease.

The guaiac FOB test is one of several methods that detects the presence of faecal occult blood (FOB). Faecal Immunochemical testing (FIT) test is a much more specific test for bleeding from the colon or lower gastrointestinal tract, it does not detect occult blood from the stomach and upper small intestine. The Qualitative Faecal Hb programme covers both FOB and FIT kits.

Scope:
Three samples distributed on a monthly basis. Samples are prepared from organic material designed to simulate the composition of human faeces.  Covers the pathological and analytical range for guaiac based faecal occult blood tests (gFOBT) and qualitative Faecal Immunochemical Tests (FIT). Samples are also distributed to challenge kit cut-offs.


Key Features:

  • Material closely mirrors the basic constituents of human faeces.
  • Covers the pathological and analytical range for guaiac based faecal occult blood tests (gFOBT) and Qualitative Faecal Immunochemical tests (FIT).
  • Samples distributed to challenge kit cut-offs.
