i-Chroma iFOB Neo

Faecal occult blood test (FOB)  checks for blood in a stool sample. Occult blood means that the amount of blood  is so small such that it cant be seen with the  eyes. The presence of blood in the stool means there is likely some kind of bleeding in the digestive tract. This may be caused by a variety of conditions, including:

  • Polyps
  • Hemorrhoids
  • Ulcers
  • Colitis.

Blood in the stool may also be a sign of colorectal cancer.

The traditional FOB test uses the chemical Guaiac, which is sensitive to Hb peroxidase activity. However, the Guaiac-FOB test has low sensitivity to clinically significant colorectal neoplasis and has low specificity due to its non-specificity for human.

To overcome these potential challenges in immunochemical tests, i-chromaiFOB Neo uses specific monoclonal antibodies against human Hb. The patient is not forced to avoid food or medicine before the iFOB is tested. The i-chroma™ iFOB Neo contains a stabilized extraction buffer tube which can be stored in room temperature.
