Stool Culture and Sensitivity (Aerobic)
Understanding Stool Culture and Sensitivity (Aerobic)
What is Stool Culture and Sensitivity (Aerobic)?
The Stool Culture and Sensitivity (Aerobic) test helps detect the presence and type of bacteria causing the infections in the gastrointestinal (digestive) tract. This test distinguishes between the types of bacteria that cause disease (pathogenic) and the types that are normally found in the gastrointestinal tract (normal flora). Additionally, it helps determine which antibiotics are effective against the identified bacteria.
The Stool Culture and Sensitivity (Aerobic) test helps to detect bacterial infections (specifically targeting aerobic bacteria (that need oxygen to grow)) in the gastrointestinal tract. Normally, certain bacteria (normal flora) inhabit everyone’s gastrointestinal tract. They play an important role in the digestion of food and their presence keeps a check on the growth of disease-causing bacteria (pathogenic). Sensitivity testing is done to identify which antibiotics are most effective against these pathogenic bacteria.
The most common symptoms of a pathogenic bacterial infection are prolonged diarrhea, bloody diarrhea, mucus in the stool, abdominal pain and cramping, and nausea. This test helps determine the cause of digestive conditions such as bacterial gastroenteritis, diarrhea, dysentery, food poisoning, etc.
By accurately identifying the bacterial pathogen and their antibiotic susceptibilities, the Stool Culture and Sensitivity (Aerobic) test plays an important role in managing and treating bacterial infections in the gastrointestinal system.
No special preparation is required for this test. However, use the sample collection container provided by the laboratory personnel and ensure that the sample does not get contaminated with urine, water, or other substances. Inform your doctor about all the medications or supplements that you are taking, as certain medications or compounds will render the stool specimens unsatisfactory for examination. The specimens should be collected before these substances are administered, or collection must be delayed until after the effects have passed.
Lab test results may vary across laboratories. Do not self-medicate at home solely based on these test results and always consult your doctor for proper understanding of the test results. The insights from the Stool Culture and Sensitivity (Aerobic) test will help doctors prescribe targeted treatments ensuring effective and appropriate medical care.
What is Stool Culture and Sensitivity (Aerobic) used for?
The Stool Culture and Sensitivity (Aerobic) test is done:
- To identify the specific bacteria in the digestive tract that may be causing symptoms such as abdominal pain, diarrhea, fever, etc.
- To distinguish between disease causing bacteria (pathogenic) and normal gut flora.
- To evaluate and monitor conditions like gastroenteritis, food poisoning and other gastrointestinal infections.
- To help prevent potential complications from untreated bacterial infections, such as severe dehydration, or other systemic infections.
- To help identify and track outbreaks of food borne illnesses by identifying the bacterial source.
- To identify the antibiotic-resistant bacteria and ensure the use of effective antibiotics, thus preventing the spread of resistant strains.
- To investigate the cause of recurrent or chronic gastrointestinal symptoms.
- In conjunction with other tests to support the diagnosis of specific gastrointestinal disorders that are associated with bacterial infections.
What does Stool Culture and Sensitivity (Aerobic) measure?
The Stool Culture and Sensitivity (Aerobic) test measures the presence and type of aerobic bacteria in the digestive tract, specifically those causing infections and illnesses. If bacteria are found in the culture, sensitivity testing is done to determine which antibiotics are effective against the identified bacteria. This information helps doctors diagnose bacterial infection accurately and select the most appropriate and effective antibiotic treatment, ensuring better management of the infection and treatment response.
Interpreting Stool Culture and Sensitivity (Aerobic) results
Interpretations
-
A positive result means that there is growth of a pathogenic microorganism in the stool sample, which indicates an infection.
-
A negative result means that there are no pathogenic organisms present in the stool sample.
