DNA Entamoeba histolytica (dysentery amoeba) — PCR, qualitative
Detects Entamoeba histolytica DNA — parasite causing amebiasis and acute intestinal infections. PCR detects genetic material even when eggs/cysts are destroyed.
Infection routes:
- unwashed vegetables, fruits, greens;
- contaminated water; poor hygiene;
- contact with infected persons.
Recommended for:
- persons with acute or chronic intestinal symptoms;
- negative microscopy results;
- frequent digestive disorders.

- Deliver within 2-3 hours; store at +2 to +8°C up to 8-12 hours if needed
Medications: If taking antiparasitic drugs — inform physician; collect before treatment if possible

- Diarrhea, mucous or bloody intestinal discharge;
- abdominal pain, bloating;
- nausea, reduced appetite;
- weakness, fatigue;
- elevated temperature without obvious cause;
- suspected intestinal 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.
Infectious disease parasitologist consultation recommended. Self-treatment not recommended.
