DNA Strongyloides stercoralis (intestinal threadworm) — PCR, qualitative
Detects Strongyloides stercoralis DNA — roundworm causing strongyloidiasis. PCR detects genetic material even when eggs/larvae destroyed. More sensitive than microscopy.
Infection routes:
- contaminated soil or sand;
- soil contact;
- unwashed vegetables, fruits, water; poor hygiene.
Recommended for:
- children and adults with chronic intestinal symptoms;
- soil/agricultural workers;
- elevated eosinophils;
- negative microscopy results.
Biomaterial: Stool
No separate preparation indicated in source description.
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 usually not earlier than 2-3 weeks.
Abdominal pain; diarrhea or constipation; reduced appetite, nausea; unexplained allergic reactions; elevated eosinophils; unexplained cough, bronchitis; weakness, fatigue; 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.
Infectious disease parasitologist consultation recommended. Self-treatment not recommended.
