DNA Trichuris trichiura (whipworm) — PCR, qualitative
Detects Trichuris trichiura DNA — roundworm causing trichuriasis. PCR detects genetic material even when eggs/larvae destroyed. More sensitive than microscopy.
Infection routes:
- contaminated hands;
- unwashed vegetables, fruits, berries;
- soil contact; poor hygiene.
Recommended for:
- children and adults with intestinal symptoms;
- persons with chronic allergies or anemia;
- prolonged intestinal symptoms;
- negative microscopy results.
Biomaterial: Stool
- Do not take laxatives 2-3 days before
- Do not use enemas or rectal suppositories
- Collect stool naturally; exclude urine and water contamination
- Use sterile container; collect from 3-5 different areas
- 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
Note: PCR testing after treatment is usually done no earlier than 2-3 weeks after.
- Abdominal pain;
- diarrhea or constipation;
- reduced appetite, nausea;
- anemia or weakness;
- unexplained allergic reactions;
- suspected parasitic infection;
- negative microscopy with symptoms.
Note: Test detects even small parasite DNA fragments.
Negative — T. trichiura DNA not detected.
Positive — T. trichiura DNA detected; confirms parasite presence.
Physician consultation required at positive result.
Infectious disease parasitologist consultation recommended. Self-treatment not recommended.
