Lab Tests that Differentiate Bali Belly and Dengue: What Matters Most
In Bali, gastrointestinal issues and viral infections are common among both locals and travelers. Two of the most frequently encountered health problems are Bali Belly (traveler’s diarrhea) and Dengue Fever. Both can present with overlapping symptoms such as fever, nausea, and abdominal discomfort, making accurate diagnosis critical for proper management. Understanding which lab tests are essential in differentiating these two conditions helps ensure timely and effective treatment.
Understanding the Conditions: Bali Belly vs. Dengue
Bali Belly (Traveler’s Diarrhea)
Bali Belly is a colloquial term for acute gastroenteritis, most often caused by consuming contaminated food or water. Symptoms typically include:
• Watery diarrhea
• Abdominal cramps
• Nausea and vomiting
• Fever (sometimes)
• Occasional headache or muscle aches

Dengue Fever
Dengue Fever is a mosquito-borne viral infection endemic to Bali. It’s characterized by a sudden onset of:
• High fever
• Severe headache, especially behind the eyes
• Muscle and joint pain
• Skin rash
• Nausea and vomiting
• Low white blood cell count and thrombocytopenia (low platelets in severe cases)
Dengue can progress to a more severe form, dengue hemorrhagic fever, which requires urgent medical care.
Why Proper Diagnosis Matters
Bali Belly and Dengue share certain symptoms, but their treatments differ significantly. Misdiagnosis can delay effective therapy and lead to complications. Quick and accurate differentiation is essential for:
• Prompt symptom management
• Preventing complications (e.g., dehydration from Bali Belly, hemorrhagic complications from Dengue)
• Ensuring appropriate isolation or public health measures
Key Lab Tests: What Health Professionals Look For
1. Complete Blood Count (CBC)
A CBC helps differentiate between Bali Belly and Dengue through several parameters:
• White Blood Cell Count (WBC): Dengue frequently causes a low WBC (leukopenia), while Bali Belly may show a mild to moderate increase (leukocytosis), especially if caused by bacteria.
• Platelet Count: Dengue often leads to a significant drop in platelets (thrombocytopenia), especially after the third day of illness. Bali Belly usually does not affect platelet levels.
• Hematocrit: Elevated hematocrit in Dengue can indicate plasma leakage, a sign of severe disease. Bali Belly rarely affects hematocrit unless there’s significant dehydration.
At Trishnanda Care Centre, our in-villa lab tests include rapid CBC panels to provide quick, actionable results.
2. Dengue NS1 Antigen Test
The NS1 antigen test detects the dengue virus within the first five days of symptom onset. It is highly specific:
• Positive NS1: Confirms dengue infection early, even before antibodies develop.
• Negative NS1: Does not rule out dengue if symptoms persist, further antibody (IgM/IgG) testing may be needed.
This test is not useful for diagnosing Bali Belly.
3. Dengue IgM and IgG Antibody Tests
If the NS1 is negative but clinical suspicion remains, IgM and IgG serology tests can help:
• IgM: Appears within 4-5 days after symptom onset, indicates recent infection.
• IgG: Indicates past or secondary infection.
These tests are not relevant for Bali Belly diagnosis.
4. Stool Analysis
For suspected Bali Belly, a stool test identifies the cause:
• Microscopy and Culture: Can identify bacterial, viral, or parasitic pathogens causing diarrhea.
• Leukocytes/RBCs in Stool: May indicate bacterial infection or colitis.
Stool tests are not useful for diagnosing Dengue.
5. Electrolyte Panel
Both Bali Belly and Dengue can cause dehydration. A basic metabolic panel checks for:
• Sodium, potassium, chloride, bicarbonate
• Renal function (creatinine, urea)
This helps guide IV hydration therapy and monitor for complications.
Explore hydration IV therapy options for rapid electrolyte replacement.
What Matters Most: Red Flags That Demand Urgent Testing
• High persistent fever (over 39°C)
• Severe abdominal pain or persistent vomiting
• Bleeding gums, nosebleeds, or unusual bruising
• Signs of dehydration (sunken eyes, dry mouth, low urine output)
• Rash or persistent muscle and joint pain
If you or someone you know develops these symptoms, contact a healthcare provider immediately. Trishnanda Care Centre offers 24/7 doctor-on-call and nurse visits across Bali.
