Urine examination
Identify
A stool test is a diagnostic tool used to analyze a sample of stool (feces) to assess various aspects of gastrointestinal (GI) health. It helps detect infections, inflammation, bleeding, malabsorption, and other conditions affecting the digestive system. Stool tests are non-invasive, making them a common and essential diagnostic step in evaluating symptoms like diarrhea, abdominal pain, or unexplained weight loss.

Types of Stool Tests
Stool Culture:

Identifies bacterial, viral, or parasitic infections.
Commonly used to detect pathogens like Salmonella, E. coli, or Clostridioides difficile.
Fecal Occult Blood Test (FOBT):

Screens for hidden (occult) blood in the stool.
Often used to check for colorectal cancer or GI bleeding.
Fecal Calprotectin Test:

Measures calprotectin, a marker of inflammation.
Useful in diagnosing inflammatory bowel disease (IBD) and distinguishing it from irritable bowel syndrome (IBS).
Ova and Parasite Test (O&P):

Detects parasites and their eggs (ova), such as Giardia or Entamoeba histolytica.
Common in cases of persistent diarrhea, especially after travel.
Fecal Fat Test:

Measures fat content in stool to diagnose malabsorption disorders like celiac disease or pancreatitis.
Stool pH Test:

Analyzes the acidity or alkalinity of stool, which can indicate malabsorption or infection.
Stool DNA Test:

Identifies abnormal DNA shed by cancer cells.
Used in colorectal cancer screening (e.g., Cologuard).
Reasons for a Stool Test
Persistent diarrhea or constipation
Bloody or black stools
Unexplained weight loss or malnutrition
Abdominal pain or cramping
Screening for colon cancer
Diagnosing infections or inflammatory disease
