Can You Give a Stool Sample If You Have Diarrhea?: A Comprehensive Guide
In most cases, yes, you can give a stool sample if you have diarrhea. In fact, diarrheal stool samples are often more informative for detecting certain infections and issues.
Understanding the Purpose of Stool Samples
Stool samples, also known as fecal samples, are an essential diagnostic tool used to identify various gastrointestinal (GI) problems. They offer a non-invasive way to analyze the contents of your digestive system, providing valuable insights into the health of your gut. Can You Give a Stool Sample If You Have Diarrhea? is a question that many patients ask their doctors. It’s important to understand that the answer often depends on the reason for the stool sample request.
Here are some of the common reasons why a doctor might order a stool sample:
- Detecting bacterial, viral, or parasitic infections
- Identifying the presence of blood in the stool (which could indicate ulcers, inflammation, or cancer)
- Analyzing digestive enzymes and fat content to assess pancreatic function
- Screening for colorectal cancer through fecal occult blood tests (FOBT) or fecal immunochemical tests (FIT)
- Evaluating inflammatory bowel disease (IBD), such as Crohn’s disease and ulcerative colitis
Why Diarrheal Stool Samples Can Be Important
Contrary to what some might believe, a diarrheal stool sample can be particularly useful in certain situations. This is because:
- Higher Concentration of Pathogens: When you have diarrhea, your body is trying to eliminate something quickly. This often means a higher concentration of the infectious agent (bacteria, virus, or parasite) in the stool.
- Easier Detection: The watery consistency of diarrheal stool allows for easier detection of certain pathogens or markers that might be missed in a more solid sample.
- Specific Diagnostic Needs: Many tests specifically require a diarrheal sample to accurately identify the cause of the problem.
However, it’s absolutely critical to follow your doctor’s specific instructions for collecting the sample.
The Stool Sample Collection Process
The collection process for a stool sample is generally straightforward, but precise adherence to the instructions is crucial for accurate results. Here’s a general outline:
- Obtain a Collection Kit: Your doctor will provide you with a kit containing a sterile container, instructions, and possibly a collection device (e.g., a hat or plastic wrap to place over the toilet bowl).
- Timing Matters: Follow the specific instructions regarding timing. Some tests require immediate delivery of the sample to the lab.
- Avoid Contamination: Do not let urine or toilet water contaminate the stool sample. This is why the collection device is essential.
- Collect a Sufficient Amount: The instructions will specify the amount of stool needed (usually a small portion, about the size of a walnut).
- Seal and Label: Properly seal the container and label it with your name, date of birth, date and time of collection, and your doctor’s name.
- Transport: Deliver the sample to the lab according to the instructions provided. Keep it refrigerated if necessary.
Common Mistakes to Avoid
To ensure the accuracy of the test results, it’s important to avoid these common mistakes:
- Contamination: As mentioned earlier, avoid contaminating the sample with urine or toilet water.
- Insufficient Sample: Not collecting enough stool can lead to inaccurate results.
- Improper Storage: Failing to refrigerate the sample when required can degrade the sample and affect the test results.
- Medication Interference: Inform your doctor about any medications you are taking, as some can affect stool test results. For example, antibiotics can alter the gut microbiome.

Frequently Asked Questions (FAQs)
What if I can’t produce a stool sample on the day I’m supposed to?
- If you are unable to produce a stool sample on the scheduled day, contact your doctor or the lab immediately. They will advise you on whether you need to reschedule or if you can collect the sample on a different day. Timing is critical for some tests, so it’s best to get clear instructions.
How long can I store a stool sample before taking it to the lab?
- The storage time for a stool sample varies depending on the specific test. Some samples need to be delivered to the lab within an hour of collection, while others can be refrigerated for up to 24-72 hours. Always follow the instructions provided with your collection kit.
What happens if my stool sample gets contaminated?
- If your stool sample becomes contaminated with urine, toilet water, or anything else, you should collect another sample, if possible. Contamination can compromise the accuracy of the test results, leading to false positives or false negatives. If you can’t collect another sample, inform your doctor.
Can I collect a stool sample if I am taking antibiotics?
- Yes, you can collect a stool sample if you are taking antibiotics, but you should always inform your doctor about it. Antibiotics can affect the composition of your gut bacteria, which can influence the test results. The doctor may advise you to wait until after you have finished your antibiotic course before collecting the sample.
Is it safe to handle a stool sample myself?
- Yes, it is generally safe to handle a stool sample, as long as you follow proper hygiene practices. Always wash your hands thoroughly with soap and water after handling the sample container. Avoid touching the inside of the container and keep it away from food preparation areas.
What if I accidentally spill some of the stool sample?
- If you accidentally spill some of the stool sample, clean the affected area with a disinfectant and wash your hands thoroughly. If the spill is significant, and there is not enough sample left in the container, it’s best to collect another sample, if possible.
Can I eat normally before giving a stool sample?
- In most cases, you can eat normally before giving a stool sample. However, some tests may require you to avoid certain foods or medications. Your doctor will provide specific instructions if any dietary restrictions are necessary.
What do the different colors of stool mean?
- Changes in stool color can indicate various underlying health conditions. Black stool can suggest bleeding in the upper GI tract, while red stool might indicate bleeding in the lower GI tract. Green stool can be caused by diet or certain infections. Consult your doctor if you notice any significant or persistent changes in your stool color.
How will I receive the results of my stool sample test?
- Your doctor will typically contact you with the results of your stool sample test. The time it takes to receive the results can vary, depending on the specific test and the lab performing the analysis. Your doctor will explain the results to you and discuss any necessary treatment options.
What types of parasites can be detected in a stool sample?
- A stool sample can detect a variety of parasites, including Giardia, Cryptosporidium, Entamoeba histolytica, and worms like tapeworms and hookworms. These parasites can cause various symptoms, such as diarrhea, abdominal pain, and nausea.
What if the stool sample test comes back positive?
- If your stool sample test comes back positive, it means that the test has detected an abnormality, such as an infection, inflammation, or blood. Your doctor will explain the results to you and recommend the appropriate treatment based on the specific finding.
Are there any alternative methods to stool samples for diagnosing GI issues?
- Yes, there are several alternative methods for diagnosing GI issues, including colonoscopy, endoscopy, sigmoidoscopy, and imaging tests like CT scans and MRIs. These methods are often used when stool samples are inconclusive or when a more detailed examination of the GI tract is needed. Your doctor will determine the most appropriate diagnostic approach based on your individual symptoms and medical history.
