Understanding Your Results
Positive for pathogen
Confirms infection with the identified organism. Consult a specialist for treatment.
Negative
No detectable eukaryotic pathogen. Consider other diagnostic tests if symptoms persist.
Inconclusive
Repeat testing or use alternative methods may be needed.
Consult a doctor if you experience symptoms like fever, diarrhea, or skin rash, especially after travel or in immunocompromised states. Follow up on test results for appropriate management.
