Feces

This test is performed to verify if there is an infection with a parasite as the cause. Amoeba belongs to this group and amoebic dysentery is caused by one of them, with excessive diarrhea as a consequence. There are several other types that are occasionally seen in the feces as cysts. They are usually not considered pathogenic.

This test verifies to what extent nutrients (like protein, carbohydrates and fat) from the stomach- intestinal tract are digested or absorbed. If there is any digestive disorder, the nutrients are not digested accordingly in the intestine. This can be caused by pancreas problems, bile salts deficiency or enzyme abnormalities. What we eat and drink is not always absorbed by the body. This is certainly not the case when there is an absorption disorder (malabsorption): the nutrients are not or not completely digested accordingly in the intestine. This can be caused by the absence of Pancreatic enzymes to break down the protein, the deficit of bile acid to digest fat or an unstable intestine.

The main use for the fecal occult blood test (FOBT) or the fecal immunochemical test (FIT) is as a screen for early colon cancer. Blood in the stool may be the only symptom of early cancer; thus, if detected early, treatment can begin immediately, improving the chance of a cure. The FOBT is not diagnostic for cancer but, if positive, requires other follow-up procedures to find the source of the bleeding that may indicate other gastrointestinal problems. The fecal occult blood test (FOBT) or fecal immunochemical test (FIT) check for hidden blood in the stool. Normally, only very small amounts of blood may be lost from the stomach or intestines during digestion. This blood cannot be seen in the feces and does not produce a positive result on a fecal occult blood test. However, polyps, finger-like growths that protrude into the intestinal cavity (lumen) or in the rectum, can be fragile and bleed intermittently, such as when food waste brushes against them. The blood released is not usually visible in the stool but can be detected with a fecal occult blood test. A secondary use of FOBT is to determine the cause of anemia, such as blood loss from a bleeding ulcer.

This test is performed to determine the presence of Helicobacter pylori in feces. Helicobacter pylori is a bacterium that usually appears in the stomach. This bacterium is resistant to gastric acid. This test provides evidence of the existence of the antigen of the bacterium. It can be repeated at least four weeks after a complete treatment to check the existence of the antigen.
