Dientamoeba fragilis
Description
The pathogenic role of Dientamoeba fragilis has not been established.
If detected — guidance
Antimicrobial treatment is usually unnecessary and may disrupt the gut microbiome without clearing the protozoa. For symptomatic cases, other causes (e.g. infections, IBS, food intolerances) should be excluded. Screening for organism clearance or testing family members is not recommended.
If not detected
Indicates the pathogen has been tested and not detected in the sample.
If indeterminate
Discrepant test results cannot be resolved as positive or negative. If clinically indicated, repeat sample collection and further testing are recommended.
What are pathogen markers?
Pathogens are bacteria, viruses or protists that can cause infection and disease. Pathogens are tested using RT-PCR (real-time polymerase chain reaction) — a highly sensitive method for detecting specific regions of DNA that typically indicate the presence of the pathogen, species or genus reported. Results for each of the 18 Pathogen Markers are displayed on the marker card, along with insights for patient management.
If not detected
The pathogen has been tested and not detected in the sample.
If indeterminate
Discrepant test results cannot be resolved as positive or negative. If clinically indicated, repeat sample collection and further testing is recommended.
If detected — guidance
The pathogen has been detected. Always interpret in the context of the patient's clinical presentation.
