Short answer: If stomach trouble lingers after a
bout of “Bali belly” — ongoing diarrhoea, bloating, cramps or fatigue
lasting more than a few days — the useful tests are a stool
analysis (ova and parasites / microscopy), sometimes with
antigen tests for specific bugs like Giardia, and a stool
culture if a bacterial cause is suspected. International-standard
hospitals (BIMC, Siloam, Bali International Hospital), expat clinics,
and reputable private labs across Denpasar, Sanur and Canggu all offer
these, usually with 1–3 day turnaround for around
IDR 250,000–1,200,000 (USD 16–75) depending on the
panel. This guide compares where to test and how to choose — it

When a stool/parasite
test is worth it
Most short-lived travellers’ diarrhoea resolves on its own with rest
and rehydration. Testing becomes worthwhile when symptoms are prolonged
or severe. Consider seeing a doctor and testing if you have:
- Diarrhoea lasting more than 5–7 days, or that keeps
returning. - Persistent bloating, greasy stools, cramps or unexplained
weight loss after a gut illness. - Blood or mucus in the stool.
- Fever with the diarrhoea, or signs of
dehydration. - Ongoing fatigue that started after a stomach
illness.
Seek prompt medical care (not just a lab test) for high fever,
significant blood in the stool, severe dehydration, or symptoms in a
young child, older adult or pregnant traveller.
What’s usually tested
| Test | What it looks for | Typical turnaround |
|---|---|---|
| Stool ova & parasites (microscopy) | Parasites and their eggs, incl. amoeba | 1–2 days |
| Giardia / Cryptosporidium antigen | Specific common travel parasites | 1–2 days |
| Stool culture | Bacterial causes (e.g. Salmonella, Shigella) | 2–3 days |
| Full blood count | Signs of infection/inflammation | Same day |
| Faecal calprotectin (sometimes) | Gut inflammation | 1–3 days |
Indicative panel — the doctor decides what to run based on your
symptoms. See our tests-explained pillar
for what each result means.
Where to get tested in Bali
| Provider type | Strength | Indicative cost (IDR / USD) | Best for |
|---|---|---|---|
| Int’l-standard hospital | Doctor review + treatment if positive | 600k–1.5m / 38–95 | Severe/prolonged cases, needing a specialist |
| Expat clinic | Convenient assessment + prescription | 400k–1.0m / 25–63 | Typical lingering “Bali belly” |
| Reputable private lab | Cheapest for the test alone | 250k–700k / 16–44 | When a doctor is already directing care |
Indicative ranges from publicly listed Bali provider rates,
reviewed quarterly. Confirm before visiting. Benchmarked against our Bali medical check-up price
guide.
Because a positive stool test usually needs the right
treatment (different parasites need different medicines), prioritise a
provider where a doctor reviews the result and can
prescribe — not just a lab that hands you a report. Compare
facilities by area in our clinics and hospitals
directory.
How to collect and what to
bring
- Follow the collection instructions — some parasites
are shed intermittently, so doctors may request samples on different
days. - Note your symptom timeline and any recent food/water
exposures. - List any antibiotics or anti-diarrhoeals you’ve
already taken — they can affect results. - Bring your passport and insurance details.
Medical disclaimer: This guide is for information
only and is not medical advice. Persistent gastrointestinal symptoms can
have many causes; diagnosis and treatment must come from a licensed
physician who has assessed you and your test results. Do not self-treat
with antiparasitic or antibiotic medicines without medical guidance.

Why the right test and
treatment matter
Travellers’ diarrhoea is common, and while most cases are
self-limiting, a minority are caused by parasites that persist without
targeted treatment. The World Health Organization notes that persistent
diarrhoea warrants investigation for parasitic and other causes so that
appropriate, specific treatment can be given rather than repeated
empirical courses (World Health Organization, Diarrhoeal
disease, who.int). That’s the practical reason to choose a clinic
that both tests and interprets — and treats — the result.
Pairing with a wider
check-up
If your gut trouble followed a longer stay, some travellers add a
broader baseline screen once recovered. See what a comprehensive check
includes in our tests-explained pillar,
and compare top providers in the best Bali medical check-ups
guide.
Frequently asked questions
How long should I wait before testing after Bali
belly? Most short-lived travellers’ diarrhoea clears on its own
within a few days. If symptoms last more than 5–7 days, keep returning,
or come with blood, mucus, fever or weight loss, that’s the point to see
a doctor and test. Sooner if you’re dehydrated or in a higher-risk group
(young child, older adult, pregnant).
Do I need a doctor, or can I just order a stool
test? Some labs run stool tests directly, but a positive result
usually needs the right prescription — different parasites and
bacteria require different medicines. Choose a provider where a doctor
reviews the result and can treat you, rather than a report with no
follow-up. Compare doctor-led options in our clinics and hospitals
directory.
Why might the doctor ask for samples on different
days? Some parasites are shed intermittently, so a single
sample can miss them. Collecting on separate days improves the chance of
catching them. Follow the collection instructions carefully — good
sampling is half the accuracy.
Can antibiotics I already took affect the result?
Yes. Antibiotics and anti-diarrhoeal medicines can alter what shows up
on a stool test, so tell the clinic exactly what you’ve already taken
and when. This helps the doctor interpret the result and decide whether
to retest.
How much does parasite/stool testing cost in Bali? A
stool panel typically runs IDR 250,000–1,200,000 (USD 16–75) depending
on how many tests are included, with 1–3 day turnaround at reputable
providers. Benchmark against our price
guide.
