Overview
The purpose of this test is to detect the presence of Listeria monocytogenes RNA in clinical specimens. It aids in the diagnosis of listeriosis, especially in high-risk populations. Early detection helps in initiating appropriate antibiotic treatment, reducing morbidity and mortality. It is also used for screening in suspected outbreaks or food contamination investigations.

- Ensure sterile collection containers are used
- For CSF, collect in a sterile tube and transport immediately
- For stool or rectal swab, use appropriate transport media
- Label the sample with patient details and collection time
Doctor's Notes
Reviewed by Dr Kothari Ramesh Shantilal — MBBS, MD (Microbiology) · Reg. No. 27670
"Listeria monocytogenes infection can be severe in pregnant women, neonates, and immunocompromised individuals. Early detection using RNA amplification is highly sensitive and can guide timely antibiotic therapy."

Understanding Your Results
Positive
Listeria monocytogenes RNA detected. Indicates active listeriosis. Clinical correlation and prompt treatment required.
Negative
Listeria monocytogenes RNA not detected. Infection unlikely, but if symptoms persist, consider alternative diagnosis or repeat testing.
Consult a doctor immediately if you experience fever, muscle aches, or gastrointestinal symptoms, especially if you are pregnant, elderly, or immunocompromised. Early diagnosis and treatment are crucial.
Limitations
- ⚠Qualitative test does not provide bacterial load quantification
- ⚠Negative result does not completely rule out infection if sample is inadequate
- ⚠Results should be correlated with clinical findings
- ⚠RNA may degrade if sample is not processed promptly
Risks & Considerations
- ●Minimal risk of bruising at venipuncture site
- ●Rare risk of infection at collection site
- ●For CSF collection, risk of headache or bleeding (rare)
Interfering Factors
- ●Improper sample collection or storage may degrade RNA
- ●Presence of PCR inhibitors in the sample
- ●Cross-contamination during collection or processing
- ●Recent antibiotic therapy may reduce bacterial load
Compare With Similar Tests
| Test | Listeria Monocytogenes (RNA Detection) Qualitative Test | Listeria Culture | Listeria Antigen Test | Listeria Antibody Test |
|---|---|---|---|---|
| Comparison | Listeria Monocytogenes (RNA Detection) Qualitative Test | Culture is the gold standard but takes 5-7 days. RNA detection is faster and more sensitive. | Antigen tests are less sensitive than RNA detection and may give false negatives. | Antibody tests indicate past exposure, not active infection. RNA detection confirms current infection. |
