stool test is a series of tests performed on a stool sample to help diagnosis certain conditions that affect the digessive tract, these conditions may include infection such as parasites and bacteria. Read More
Stool analysis, also known as stool testing or fecal analysis, is a diagnostic procedure that examines the stool to identify and diagnose various gastrointestinal and systemic conditions. Here's a detailed overview of stool analysis, including its purposes, types, procedures, and interpretations.
Stool analysis is used to:
Diagnose Gastrointestinal Disorders: Such as infections, inflammation, and malabsorption syndromes.
Detect Blood in Stool: Which can indicate gastrointestinal bleeding, hemorrhoids, or more serious conditions like colorectal cancer.
Identify Parasites and Pathogens: Including bacteria, viruses, and protozoa.
Evaluate Digestive Health: Assessing how well the digestive system is functioning.
Prescence of Blood in Stool
Mucus in stool
Diarrhea lasting more than three days
Stomach pain or cramping
Nausea or vomiting lasting days
Fever
Persistent digestive symptoms such as abdominal pain, bloating, constipation, or changes in stool consistency
Colitis (swelling or irritation in your colon, part of your intestine).
Colon polyps (small clumps of cells in the colon).
Colorectal (colon) cancer.
Exocrine pancreatic insufficiency (EPC) (not able to break down food in the intestines).
Gastrointestinal (GI) bleeding.
Hemorrhoids (swollen veins in your anus).
Infections (bacterial, viral, or parasitic).
Inflammatory bowel disease (IBD) (irritation in your digestive tract).
Stomach ulcers (sores in your stomach).
Macroscopic analysis
Macroscopic analysis involves making assessments about the stool’s obvious characteristics, such as:
the stool’s appearance, such as its color, shape, and consistency
the stool’s odor
the presence of mucus or blood
Microscopic analysis
Microscopic analysis involves examining the stool under a microscope to check for the following:
Infectious pathogens
Blood in the stool
Fat in the stool
Ova and parasites in stool
Undigested food in stool
Mucous in stool
Yeasts in stool
High levels of fat in the stool may be caused by diseases such as pancreatitis, sprue (celiac disease), cystic fibrosis, or other disorders that affect the absorption of fats.
The presence of undigested meat fibers in the stool may be caused by pancreatitis.
A low pH may be caused by poor absorption of carbohydrate or fat. Stool with a high pH may mean inflammation in the intestine (colitis), cancer, or antibiotic use.
Blood in the stool may be caused by bleeding in the digestive tract.
White blood cells in the stool may be caused by inflammation of the intestines, such as ulcerative colitis, or a bacterial infection.
stool Culture:
Purpose: Identifies bacterial infections by growing bacteria from a stool sample.
Stool Occult Blood Test:
Purpose: Detects hidden (occult) blood in the stool.
Conditions Tested For: Gastrointestinal bleeding, colorectal cancer, polyps.
Stool Lactoferrin Test:
Purpose: Detects the presence of lactoferrin, a protein associated with inflammation.
Conditions Tested For: Inflammatory bowel disease (IBD) like Crohn’s disease and ulcerative colitis.
Stool Calprotectin Test:
Purpose: Measures the level of calprotectin, a protein associated with inflammation.
Conditions Tested For: Inflammatory bowel disease (IBD), and differentiates between IBD and irritable bowel syndrome (IBS).
Stool C. difficile Test:
Purpose: Detects toxins produced by Clostridium difficile bacteria.
Conditions Tested For: Clostridium difficile infection, which often follows antibiotic use.
stool Reducing Substances Test:
Purpose: Detects the presence of unabsorbed sugars.
Conditions Tested For: Carbohydrate malabsorption conditions such as lactose intolerance.
It will take several hours to get the result.
