Test Parameters & Specifications
Sample Stability
- Hemolyzed, lipemic, or contaminated samples
- Improperly labeled or insufficient sample volume
- Samples stored beyond stability limits
Understanding Your Results
Positive (IgM antibodies detected)
Suggests current or recent scrub typhus infection. Consult a physician for treatment with antibiotics like doxycycline.
Negative (No IgM antibodies detected)
No detectable immune response to Orientia tsutsugamushi. If symptoms persist, repeat testing or alternative diagnoses should be considered.
Equivocal (Borderline levels)
Indeterminate result. Repeat testing after 7-10 days or perform confirmatory tests for accurate diagnosis.
If you test positive or experience persistent symptoms like high fever, severe headache, or difficulty breathing, consult a doctor immediately for appropriate treatment.
Limitations
- ⚠May not detect early infections before antibody production (window period)
- ⚠Equivocal results may require repeat testing or confirmatory assays
- ⚠Cannot distinguish between current and past infections without IgG testing
Risks & Considerations
- ●Minor bruising or pain at the blood draw site
- ●Rare risk of infection or dizziness
- ●No significant risks associated with the test itself
Interfering Factors
- ●Cross-reactivity with other rickettsial infections (e.g., murine typhus)
- ●Recent vaccination or prior infection may affect antibody levels
- ●Hemolyzed, lipemic, or contaminated samples can interfere with results
