Strongyloides stercoralis (intestinal threadworm)
Detects Strongyloides stercoralis — an intestinal helminth causing strongyloidiasis. Disease may be prolonged and mildly symptomatic; in immunocompromised patients may cause severe complications. Used for strongyloidiasis diagnosis and treatment efficacy monitoring.
Infection routes: skin contact with contaminated soil; barefoot walking; contaminated hands; poor hygiene; autoinvasion (self-infection).
Method: Microscopic method — Strongyloides stercoralis larval detection in stool.
Recommended for: persons from endemic regions or with soil contact; elevated eosinophil levels; prolonged allergic and intestinal symptoms; immunocompromised patients.
Biomaterial: Stool
- Collect stool naturally (no laxatives 2-3 days before);
- no enemas or rectal suppositories;
- no intestinal motility-affecting drugs;
- if taking antiparasitic or hormonal drugs — inform;
- collect before treatment if possible
Self-collection ⅓ of sterile container; deliver within 3 hours
- Prolonged abdominal pain and discomfort;
- diarrhea or unstable stool;
- nausea, vomiting;
- skin rashes, itching;
- unexplained allergic reactions;
- elevated eosinophils;
- chronic weakness and fatigue;
- cough, dyspnea of unclear cause;
- suspected parasitic infection.
Note: Larval shedding may be intermittent; repeat testing or comprehensive diagnostics recommended at negative result with symptoms.
Negative — S. stercoralis larvae not detected.
Positive — S. stercoralis larvae detected; confirms strongyloidiasis.
Infectious disease parasitologist consultation required at positive result. Self-treatment contraindicated.
