DNA Clonorchis sinensis (Chinese liver fluke) — PCR, qualitative
Detects Clonorchis sinensis DNA — a parasitic trematode (liver fluke) causing clonorchiasis. Parasite affects bile ducts, liver, and pancreas. PCR detects genetic material even when eggs/larvae destroyed.
Infection routes:
- consuming raw, insufficiently cooked fish with parasite larvae;
- contact with contaminated water;
- poor hygiene.
Recommended for:
- consumers of raw or insufficiently cooked fish;
- chronic liver/gallbladder diseases;

- nausea, reduced appetite;
- digestive disorders, abdominal bloating;
- enlarged liver and lymph nodes; u
- nexplained allergic reactions;
- suspected parasitic infection;
- negative microscopy with symptoms.
Note: Test detects even small parasite DNA fragments with proper sample collection.
Negative — DNA not detected.
Positive — DNA detected; confirms parasite presence.
Physician consultation required at positive result.
