Tests
A stool test detecting hidden blood from the lower bowel; the main screening entry point for colorectal cancer programmes.
Indicators
Alpha-fetoprotein (609 aa, ~69 kDa) is encoded by the human AFP gene. This protein plays a role in the binding to copper, nickel, bilirubin and fatty acids in the fetal circulation.
Tests
A calprotectin stool test measures a protein called calprotectin in a sample of your stool (poop). The test is also called a fecal calprotectin test. It's used to check for inflammation (swelling and irritation) in your intestines.
Tests
This test measures the amount of chymotrypsin in a stool (poop) sample. Chymotrypsin is an enzyme, a protein that speeds up certain chemical reactions in your body. It is released by your pancreas (an organ behind your stomach) to help break down the protein in your food during digestion. If your pancreas is working as it should, there will be some chymotrypsin in your stool sample.

Indicators
A tetrameric complex of 2 molecules of hemoglobin subunit alpha (encoded by either the HBA1 or HBA2 gene) and 2 molecules of hemoglobin subunit gamma (encoded by either the HBG1 or HBG2 gene).
Tests
An ova and parasite test looks for intestinal parasites and their eggs (ova) by checking a sample of your stool (poop) under a microscope. The test is also called an O&P.
Tests
Prenatal cell-free DNA (cfDNA) screening is a blood test given during pregnancy . During pregnancy, some of the fetus's DNA circulates in the mother's bloodstream. A cfDNA screening checks this DNA to find out if the baby is more likely to have certain conditions caused by an abnormal number of chromosomes , such as Down syndrome .
Indicators
This gene is involved in apoptosis, hormonogenesis, focal adhesion and the formation of intercellular junctions.
