Overview
The purpose of this test is to qualitatively detect the presence of Mycobacterium leprae RNA in clinical specimens, aiding in the early and accurate diagnosis of leprosy. It is particularly useful for confirming infection in suspected cases, especially when clinical signs are inconclusive or when early detection is critical for preventing disability.

- Sample not labeled correctly
- Sample received after prolonged delay without proper storage
Understanding Your Results
Detected
Positive for Mycobacterium leprae RNA. Consistent with active leprosy infection. Clinical correlation and treatment initiation are recommended.
Not Detected
Negative for Mycobacterium leprae RNA. No evidence of infection in the tested sample. However, if clinical suspicion remains high, further testing or repeat testing may be considered.
If you experience any symptoms suggestive of leprosy, such as skin lesions with reduced sensation, numbness, or muscle weakness, consult a physician immediately. Early diagnosis and treatment are crucial to prevent complications.
Limitations
- ⚠A negative result does not completely rule out leprosy; clinical correlation is essential.
- ⚠Test detects RNA, which may degrade if sample is not processed promptly.
- ⚠Qualitative test does not quantify bacterial load.
- ⚠Results should be interpreted by a qualified physician.
Risks & Considerations
- ●Minimal risk of bleeding or infection at the sample collection site
- ●Slight discomfort during biopsy or scraping
- ●Rare chance of fainting during collection
Interfering Factors
- ●Improper sample collection or handling
- ●Insufficient sample volume
- ●Contamination during collection
- ●Inhibitors in the sample (e.g., blood, mucus)
- ●Prior antibiotic treatment may reduce RNA levels
