Introduction:
A stool routine test, also known as a fecal examination or stool analysis, is a diagnostic laboratory test that is used to investigate the presence of abnormalities in the stool. The test is used to identify the presence of bacteria, viruses, parasites, and other substances in the stool. In this blog post, we will discuss the principle, uses, procedure, observation, and microscopy of the stool routine test.
What is a routine stool test?
A Stool Routine Test analyses a stool sample to detect any underlying disease or other medical condition for which you may require treatment or even hospitalisation. It is used to detect any kind of harmful germs like bacteria, fungi, parasites, or viruses that may be present inside your gastrointestinal tract.
Principle of the Stool Routine Test:
The principle of the stool routine test is based on the visual and chemical examination of the stool to identify the presence of abnormalities. The stool sample is collected from the patient and examined for its color, consistency, and odor. The sample is also tested for the presence of blood, mucus, and fat. The test also involves the microscopic examination of the stool to identify the presence of parasites, such as Giardia lamblia and Cryptosporidium parvum.
Uses of the Stool Routine Test:
The stool routine test is used for a variety of purposes, including:
- To diagnose gastrointestinal infections, such as salmonella, shigella, and E. coli.
- To screen for colon cancer.
- To monitor the effectiveness of treatment for gastrointestinal disorders.
- To diagnose malabsorption syndromes, such as celiac disease and lactose intolerance.
Procedure of the Stool Routine Test:
The procedure of the stool routine test involves the following steps:
- Collection of Stool Sample: A stool sample is collected from the patient in a sterile container.
- Visual Examination: The sample is examined for its color, consistency, and odor.
- Chemical Examination: The sample is tested for the presence of blood, mucus, and fat.
- Microscopic Examination: The sample is examined under a microscope to identify the presence of parasites.
Observation of the Stool Routine Test:
The observation of the stool routine test involves the following:
- Color: Normal stool color is brown. Abnormal colors include black, red, and yellow.
- Consistency: Normal stool consistency is solid and formed. Abnormal consistencies include watery, loose, and hard.
- Odor: Normal stool odor is slightly unpleasant. Abnormal odors include foul-smelling and sweet-smelling.
- Blood: The presence of blood in the stool may indicate gastrointestinal bleeding.
- Mucus: The presence of mucus in the stool may indicate inflammation of the colon.
- Fat: The presence of fat in the stool may indicate malabsorption syndromes.
Microscopy of the Stool Routine Test:
Microscopy of the stool routine test involves the following:
- Wet Mount: Wet mount is used to identify the presence of parasites, such as Giardia lamblia and Cryptosporidium parvum.
- Stool Culture: Stool culture is used to identify the presence of bacteria, such as salmonella, shigella, and E. coli.
Conclusion:
In conclusion, the stool routine test is a simple and effective diagnostic laboratory test that is used to investigate the presence of abnormalities in the stool. The test involves the visual and chemical examination of the stool and the microscopic examination to identify the presence of parasites. The test is used to diagnose gastrointestinal infections, screen for colon cancer, monitor the effectiveness of treatment for gastrointestinal disorders, and diagnose malabsorption syndromes. The stool routine test is an important tool in the diagnosis and management of gastrointestinal disorders.
