The fecal immunochemical test (FIT) is a diagnostic technique that examines stool samples for traces of non-visible blood, which could potentially indicate conditions including bowel cancer. [1] Symptoms which could be caused by bowel cancer and suggest a FIT include a change in bowel habit, anaemia , unexplained weight loss, and abdominal pain .
The American College of Gastroenterology has recommended the abandoning of gFOBT testing as a colorectal cancer screening tool, in favor of the fecal immunochemical test (FIT). [3] The newer and recommended tests look for globin, DNA, or other blood factors including transferrin, while conventional stool guaiac tests look for heme.
The FeMo cofactor is a cluster with composition Fe 7 MoS 9 C. This cluster can be viewed as two subunits composed of one Fe 4 S 3 (iron(III) sulfide) cluster and one MoFe 3 S 3 cluster. The two clusters are linked by three sulfide ligands and a bridging carbon atom. The unique iron (Fe) is anchored to the protein by a cysteine.
Chemical formula of nitric oxide (NO) together with its molecular size (115 pm).. In medicine, exhaled nitric oxide (eNO - now commonly known as FeNO) can be measured in a breath test for asthma and other respiratory conditions characterized by airway inflammation.

The M2-PK Test is a non-invasive screening method for the early detection of colorectal cancers and polyps which are known to be the precursors of colorectal cancer. The M2-PK Test which is used for stool analysis is available either as fully quantitative ELISA Test or as a rapid test that can be performed by any general practitioner without the need of a laboratory or any additional equipment.
The CEA blood test is not reliable for diagnosing cancer or as a screening test for early detection of cancer. [8] Most types of cancer do not result in a high CEA level. [9] Serum from individuals with colorectal carcinoma often has higher levels of CEA than healthy individuals (above approximately 2.5ng/mL). [10]
For example, the ColoGuard test may be used to screen people over 55 years old for colorectal cancer. [57] Cancer is a longtime-scale disease with various progression steps, molecular diagnostics tools can be used for prognosis of cancer progression. For example, the OncoType Dx test by Genomic Health can estimate risk of breast cancer.
