Sample Collection
No special preparation is required. Please inform your doctor if you are taking anti-tubercular medications.
Method: Expectorated sputum collection / aseptic collection for invasive samples
Laboratory Analysis
For sputum, you will be asked to cough deeply to bring up phlegm from the lungs. For other sample types, a physician or trained staff will collect the sample under sterile conditions.
Report Delivery
The sample should be transported to the laboratory as soon as possible. If delay is expected, refrigerate at 2-8°C. Do not freeze.
Timeline: Samples submitted by 11 am are reported the same day. Reports are available online, by email or on WhatsApp.
Patient Instructions
About This Test
Who Should Get This Test
To detect the presence of Mycobacterium tuberculosis complex DNA in respiratory and selected extrapulmonary samples to aid in the diagnosis of tuberculosis.
How to Prepare
- Collect first morning sputum after deep cough into a sterile screw-capped container.
- Ensure the sample is from the lower respiratory tract, not saliva.
- Ship refrigerated at 2-8°C. DO NOT FREEZE.
- For body fluids, tissue, urine or bronchial samples, follow the collection instructions given by the laboratory or physician.
Doctor's Notes
Reviewed by Dr Kothari Ramesh Shantilal — MBBS, MD (Microbiology) · Reg. No. 27670
"TB LAMP provides a practical, rapid molecular testing solution for TB in resource-limited settings. It must be interpreted along with the patient's clinical and radiological picture."

Test Parameters & Specifications
Sample Stability
- Whole blood sample is not acceptable.
- Sample received frozen.
- Inadequate sample volume.
- Sample in a non-sterile or leaking container.
- Improperly labelled or unlabeled sample.
Understanding Your Results
Consult a physician if you have cough lasting more than 3 weeks, chest pain, blood-stained sputum, unexplained fever, night sweats or unintentional weight loss. Early diagnosis and treatment prevent spread and improve recovery outcomes.
Limitations
- ⚠Qualitative test only; does not provide bacterial load.
- ⚠Does not detect drug resistance.
- ⚠A negative result does not exclude tuberculosis; culture remains important.
- ⚠Whole blood sample is not acceptable for this test.
Risks & Considerations
- ●No significant risk for sputum collection.
- ●If invasive sample collection such as bronchoscopy is needed, there is a small risk of bleeding or infection at the sample site.
Interfering Factors
- ●Improper sample collection with excess saliva may reduce detection.
- ●PCR or LAMP inhibitors in clinical samples may rarely affect amplification.
- ●Contamination during collection or processing can cause false-positive results.
- ●Detection may be affected in patients already on anti-tubercular therapy.
