TB LAMP Application Examples

The demand for molecular test in TB diagnosis

Molecular diagnostic tests offer an important, rapid, and under-utilized molecular tool in TB (tuberculosis) diagnosis. These tests detect mycobacteria with high specificity by amplifying target nucleic acid sequences. WHO recommends that a molecular diagnostic test be performed on the first sputum sample of all suspected TB patients regardless of smear results [*1].

Innovative Tool “TB LAMP”

TB LAMP is a manual molecular test to detect Mycobacterium Tuberculosis complex (MTBC).

It takes less than 1.5 hours to perform, requires minimal instrument in the form of a heating block, and generates a fluorescent result that can be detected with the naked eye.

Additionally, it has the potential for higher throughput as it can test up to 14 samples per test run (max. 70 samples per day). TB LAMP which is a simple, accurate, robust and affordable test, has been developed for use in high burden and resource limited settings.


WHO recommendation [*1]

WHO recommends that TB LAMP may be used as a replacement for microscopy for the diagnosis of pulmonary TB in adults with signs and symptoms of TB. TB LAMP may also be considered as a follow-on test to microscopy in adults with signs and symptoms of pulmonary TB, especially when further testing of sputum smear-negative specimens is necessary. Cost effectiveness of TB LAMP is also mentioned in the policy guidance from WHO.
