Test Parameters & Specifications
Sample Stability
- Insufficient sample volume
- Hemolyzed or contaminated samples
- Improper labeling or storage
Understanding Your Results
Elevated titers may indicate brucellosis, requiring clinical correlation and further testing.
Rising titers between acute and convalescent samples support typhoid fever diagnosis.
Positive titers suggest rickettsial infections; OX19 is common in epidemic typhus, OX2 in tick-borne spotted fever, OXK in scrub typhus.
Consult an infectious disease specialist if test results are positive, if symptoms worsen, or if there is no improvement after treatment.
Limitations
- ⚠This test detects antibodies, not active infections, so recent infections may not be detected
- ⚠Cross-reactivity between similar bacteria can lead to false positives
- ⚠Does not replace culture or PCR for definitive diagnosis
Risks & Considerations
- ●Minor bruising or pain at the puncture site
- ●Rare cases of dizziness or fainting during blood draw
- ●Extremely low risk of infection at the collection site
Interfering Factors
- ●Hemolyzed or lipemic samples may affect results
- ●Recent vaccination or prior infections could cause cross-reactivity
- ●Antibiotic therapy before testing might reduce antibody levels
