It's normal for some of us to feel a little embarrassed or embarrassed when asked to do a stool test. But it's actually a simple, painless test that can reveal very important information about many diseases in your intestines. So if your doctor has asked you to do this test, don't be afraid or put it off. Let's talk about it all clearly.
Simply put, what is a stool test?
Simply put, a stool test is a test that takes a sample of your stool and examines it in a lab. Like a detective, this test looks for disease-causing germs lurking in your stool. These germs can be bacteria, viruses, or parasites . It can also detect any blood in your stool that isn't visible to the naked eye. These things can give your doctor a clue that there's something wrong with your digestive system.
What time does the doctor recommend doing this test?
If you have one or more of the symptoms below, your doctor may recommend a stool test to find the cause.
| Symptom | Description |
|---|---|
| Blood in the stool | If there is red or black blood in the stool. |
| Mucus-like discharge with stool | If something unusual, like mucus, comes out with the stool. |
| Diarrhea that lasts for several days | If you have been going hungry for more than three days. |
| Stomach ache or pain | If you have frequent stomach pain or cramps. |
| Nausea and vomiting | If nausea or vomiting that has been going on for several days goes away. |
| Fever | If you have a fever without any other obvious reason. |
What diseases can be detected by this test?
This simple test can reveal information about many conditions in your digestive system. For example:
- Infections: Stomach problems caused by bacteria, viruses, or parasites.
- Gastrointestinal (GI) bleeding: Bleeding from intestinal ulcers, hemorrhoids, etc.
- Anal fissures: Small cuts that occur where the stool comes out.
- Colitis: Inflammation of the large intestine.
- Colon polyps: These can sometimes turn into cancer.
- Colorectal cancer: To detect cancer cells.
- Inflammatory Bowel Disease (IBD): A chronic inflammatory condition of the digestive system.
- Fat in the stool (Steatorrhea): Cases where the body does not absorb fat properly.
- Anemia: If the body is constantly losing blood, it will become less red. This will help to find the cause.
Are there types of stool tests?
Yes, there are several types of tests your doctor can order depending on your symptoms.
| Name of the test | What do you see in this? |
|---|---|
| Fecal Occult Blood Test (FOBT) | This checks for blood in the stool in small amounts that are too small to be seen with the naked eye. If the result is 'positive', it means that the blood is coming from somewhere in the digestive tract. |
| FIT-DNA Test | This also checks for blood in the stool. In addition, it looks for DNA changes in cells that could lead to cancer or cancerous changes. |
| Tests for infections | These are done in several ways. The stool sample is examined under a microscope, or the germs are cultured, or the germs are tested for DNA. |
Do I need to prepare anything special before the test?
In most cases, no special preparation is needed. However, your doctor may give you special instructions before some tests.
The most important thing is that if your doctor gives you any advice (for example, to stop taking certain medications or not eat certain foods), be sure to follow it, as it can affect the accuracy of the results.
How to accurately collect a stool sample at home?
This is a problem that many people have. But it's not as difficult as you might think. The lab will provide you with the equipment you need for this (such as a sample collection bottle). Here's how to collect the sample.
1. Urinate first: If you need to urinate, do so first. Do not allow urine to get into the stool sample. Doing so may alter the results.
2. Catch the poop: Use something to keep the poop from falling into the toilet. You can use a small tray provided by the lab, or a clean plastic container for this.
3. Do not let water get into the toilet: The sample can be contaminated by the water inside the toilet or from the walls. So avoid that.
4. Place the sample in the bottle: Using the small scoop provided by the lab, take a small amount of stool and place it in the bottle provided. The bottle will be marked with the amount needed.
5. Close the bottle immediately: After adding the sample, close the bottle tightly so that it is airtight.
6. Wash your hands thoroughly: After you've done all of this, wash your hands thoroughly with soap and running water.
7. Take the sample to the lab as soon as possible: After collecting the sample, take it to the lab as soon as possible. If for some reason it is delayed, you can keep it in the refrigerator for a while. However, if it is not given within 24 hours, it is possible that the sample will not be tested.
If the result is 'Positive', what happens next?
Don't be alarmed if the result is 'Positive'. This means that the lab was able to find something in your stool (such as a germ or blood). The report will say what it is. Your doctor will use that information to find the exact cause of your symptoms and start treatment accordingly.
For example, if you have a bacterial infection, you may be given antibiotics. If there are signs of cancer, your doctor may refer you to an oncologist for further testing and treatment.
Is a stool test as good as a colonoscopy?
Both of these are important tests. But they do two different things. A stool test is basically a way to find out if there is a problem. But sometimes, in the early stages of the disease, it may not be possible to identify it from the stool.
If your symptoms persist, or if your doctor is still concerned even though your stool test results are negative, they may recommend a colonoscopy . This involves inserting a thin, flexible tube with a camera through your rectum to look inside your colon. It can also detect and remove small tumors early.
Take-Home Message
