Stool R/E Test
A stool R/E (routine examination) is a simple lab test that checks your stool for signs of infection, bleeding, or poor digestion. In Bangladesh, it is often the first test doctors order for diarrhoea, abdominal pain, or suspected parasitic infections. The test is straightforward, low-cost, and provides valuable clues about what is happening in your digestive tract.
What Does a Stool R/E Test Check For?
A stool R/E has three parts: macroscopic (what you can see — colour, consistency, mucus, blood), microscopic (looking for parasites, ova, cysts, pus cells, red blood cells), and sometimes chemical (occult blood, pH). Doctors prescribe it to investigate:
- Persistent or recurrent diarrhoea
- Dysentery (bloody or mucoid stools)
- Suspected amoebiasis, giardiasis, or other parasitic infections
- Unexplained abdominal pain or bloating
- Routine health check-ups or pre-travel screening
The test cannot diagnose every gut condition — it is a first step. If results are unclear, a stool culture or other specialist tests may be needed.
How Should You Prepare for a Stool R/E Test?
No fasting or special diet is required. However, to get accurate results, try to avoid the following for 24 hours before collecting the sample (unless your doctor says otherwise):
- Antidiarrhoeal medicines (e.g., loperamide)
- Antibiotics (they can suppress parasites or bacteria)
- Very oily or greasy foods
- Barium or other contrast agents used in X-ray exams (if you had one, wait a few days)
If you are already taking medication, ask your doctor whether you should pause it before the test.
How Is the Sample Collected and Handled?
Correct collection is key to reliable results. Follow these steps:
- Use a clean, dry, wide-mouthed container (the lab usually provides one, or you can use a small glass jar with a tight lid).
- Collect a small amount — about the size of a pea — from different parts of the stool, especially any area that looks bloody, slimy, or watery.
- Avoid mixing urine, toilet paper, or water with the sample.
- Label the container with your name, date, and time of collection.
- Deliver it to the lab within 1–2 hours. If that is not possible, keep it in a cool place (not the freezer) and transport it as soon as you can.
- Do not refrigerate unless the lab specifically tells you to.
Some diagnostic centres in Bangladesh provide a collection kit with a small spoon and tube — ask when you book the test.
What Do Stool R/E Results Mean?
The lab report will list findings under macroscopic, microscopic, and chemical sections. The table below shows common findings and what they may indicate. Remember, only a doctor can interpret results in the context of your symptoms and history.
| Finding | What It Could Suggest | Next Step |
|---|---|---|
| Brown, formed stool; no blood, mucus, or parasites | Normal — no obvious abnormality | If symptoms persist, doctor may order additional tests |
| Loose/watery stool | Possible infection (viral, bacterial, or parasitic) or malabsorption | Doctor may ask about travel, food history, and may order stool culture |
| Mucus present | Often seen in intestinal inflammation (e.g., irritable bowel, dysentery) | Clinical evaluation; may need colonoscopy if chronic |
| Pus cells (white blood cells) | Suggests inflammation — possible bacterial infection (e.g., shigellosis) | Stool culture and antibiotics (if indicated) |
| Red blood cells | Indicates bleeding in the lower digestive tract | Doctor will look for causes like haemorrhoids, fissures, or ulcers |
| Parasites (ova, cysts, or trophozoites) | Active parasitic infection (e.g., amoebiasis, giardiasis) | Specific antiparasitic medication; sometimes repeat testing after treatment |
| Occult blood (chemical test positive) | Microscopic bleeding — may be from polyps, ulcers, or early colon cancer | Usually requires colonoscopy or upper endoscopy for further investigation |
Important: A negative result does not guarantee you are infection-free. Some parasites or bacteria shed intermittently, and the sample may have missed them. If symptoms persist, your doctor may recommend a repeat test or a more sensitive test like stool culture or PCR.
How Much Does a Stool R/E Test Cost in Bangladesh?
The stool R/E test is very affordable in Bangladesh. Prices vary depending on the lab’s location (Dhaka vs outside), reputation, and whether it is part of a package. The table below gives a typical range — always confirm the current rate before having the test.
| Item | Approximate BDT Range | Notes |
|---|---|---|
| Stool R/E (routine examination) – private diagnostic lab | ৳100 – ৳200 | Common in local pathology labs and chain centres |
| Stool R/E – hospital or reputed diagnostic centre | ৳200 – ৳300 | May include detailed microscopy and chemical test |
| Stool R/E + occult blood | ৳150 – ৳350 | Occult blood is often added when GI bleeding is suspected |
| Stool culture (separate test) | ৳300 – ৳500 | Not part of R/E; ordered if bacterial infection is suspected |
Many labs in cities like Dhaka and Chattogram offer home collection for a small extra fee. Prices can change, so always ask the lab for the exact cost at the time of booking.
What Happens After the Test?
Once you receive the report, you need to consult a doctor — ideally a gastroenterologist or a general practitioner familiar with gastrointestinal issues. The doctor will correlate the findings with your symptoms, medical history, and possibly recommend:
- Medication (e.g., antiparasitics if parasites are found, or antibiotics for certain bacterial infections)
- Dietary changes (e.g., a low-fibre or gluten-free trial if malabsorption is suspected)
- Additional tests such as stool culture, colonoscopy, or imaging if the R/E was inconclusive or if bleeding or inflammation is detected
Do not start any treatment based solely on the stool R/E result. A single test is a guide, not a full diagnosis. If your symptoms continue or worsen, return to your doctor for reassessment.

Frequently Asked Questions
How long does it take to get Stool R/E test results in Bangladesh?
Most diagnostic labs in Bangladesh provide Stool R/E results within 24 to 48 hours. Some high-volume labs may offer same-day results if the sample is submitted early in the morning. However, if the lab needs to send the sample to a referral centre, it may take up to 72 hours. Always confirm the turnaround time when you submit the sample.
Can I eat or drink before collecting a stool sample for R/E?
Yes, you can eat and drink normally before a Stool R/E test. Unlike blood tests, fasting is not required. However, avoid taking antidiarrhoeal medications, antibiotics, or laxatives for 24 hours before collection unless your doctor advises otherwise, as these can alter the results. Also, avoid consuming foods with red dye or beets, which may mimic blood in the stool.
Is a Stool R/E test safe during pregnancy or for young children?
Yes, the test is completely safe for pregnant women and children of any age. It involves only collecting a stool sample — no needles, radiation, or invasive procedures. For infants, a small sample can be taken from a clean diaper. Always inform your doctor if you are pregnant or if the child has any underlying condition, but no special precautions are needed.
What should I do if I cannot produce a stool sample on the day of the test?
If you are unable to pass stool on the scheduled day, do not force it. You can collect the sample the next morning and still submit it to the lab, provided the sample is fresh (ideally within 1–2 hours of collection). Some labs accept samples collected up to 4–6 hours later if kept refrigerated in a clean, sealed container. Contact your lab for their specific policy. Do not use laxatives just to produce a sample unless your doctor instructs you to.
What is the difference between a Stool R/E test and a Stool Culture test?
A Stool R/E (routine examination) looks for physical characteristics, blood, mucus, pus, and parasites under a microscope. It is a basic screening test. A Stool Culture, on the other hand, grows bacteria from the stool to identify specific infections like Salmonella or Shigella. The culture takes longer (2–5 days) and is more expensive. Your doctor may order a culture if the R/E suggests a bacterial infection or if you have persistent symptoms. In Bangladesh, the R/E is usually done first, and a culture is added if needed.
