Stool Culture and Sensitivity is a diagnostic laboratory test that detects the presence of pathogenic bacteria in the stool and determines the antibiotics to which these bacteria are sensitive. This test is significant in identifying gastrointestinal infections that can cause diarrhea, abdominal pain, fever, and sometimes blood in the stool. Gastrointestinal infections can be caused by various bacteria, including Salmonella, Shigella, E. coli, and Campylobacter.
Knowing the specific bacteria causing the infection allows for targeted treatment with the most effective antibiotic. This is especially important as antibiotic resistance becomes more common. The stool sample is cultured in the lab under conditions that allow bacteria to grow. The bacteria are then exposed to various antibiotics to determine which ones are effective.
A stool culture and sensitivity test is a laboratory procedure where a stool sample is cultured to identify any harmful bacteria present. The bacteria are then tested against different antibiotics to determine which ones are effective in treating the infection
A doctor might order this test if you have symptoms of a gastrointestinal infection, such as diarrhea, abdominal pain, fever, or blood in the stool. It helps in identifying the specific bacteria causing the infection and in choosing the appropriate antibiotics for treatment
The stool sample should be collected in a clean, dry container. It’s essential to avoid contamination of the sample with urine or water. If you are currently taking antibiotics or other medications, inform your doctor as it may affect the results
This test can detect various bacterial infections of the gastrointestinal tract including those caused by Salmonella, Shigella, E. coli, and Campylobacter, which are common causes of food poisoning and gastroenteritis
Preliminary results are usually available within 48 to 72 hours, while final identification and sensitivity results may take up to 5 to 7 days
If your culture is positive, it means that bacteria were found in your stool sample. The sensitivity results will indicate which antibiotics are likely to be effective in treating the infection
There are no risks associated with providing a stool sample for culture. However, it’s important to provide the sample properly to avoid contamination which could affect the accuracy of the results
It’s best to avoid taking antibiotics before collecting a stool sample for culture, as they may affect the growth of bacteria in the sample. If you are currently on antibiotics, inform your doctor
The results of the test can be affected by the contamination of the stool sample with water or urine, recent antibiotic use, and the time between sample collection and analysis
No, this test is specifically designed to identify bacterial infections. Other tests are needed to diagnose parasitic or viral infections.
If the test results indicate a bacterial infection, it’s important to follow your doctor’s recommendations for treatment, which will likely include antibiotics that the bacteria are sensitive to.
Yes, improper hygiene during sample collection can contaminate the stool sample with bacteria normally present on the skin or in the environment, which can affect the results.
If your test results are abnormal, you should consult a gastroenterologist or your primary care doctor to discuss treatment options.
After sample collection, make sure the sample container is sealed properly to prevent leakage, and wash your hands thoroughly. Follow any additional instructions provided by the laboratory or your doctor regarding the transportation of the sample to the laboratory.
