This week WAidid suggests to read "The Global Laboratory Initiative. GLI Model TB Diagnostic Algorithms".
The Global Laboratory Initiative has released this handbook that provides 4 model algorithms that graphically depict the most up-to-date WHO recommendations on use of TB diagnostics.
The algorithms follow the principles of the End TB Strategy to provide universal access to rapid testing for Mycobacterium tuberculosis complex bacteria (MTB) and drug susceptibility testing (DST), and include the use of Xpert MTB/RIF, line probe assays for 2nd line drugs, the lateral flow urine lipoarabinomannan (LF-LAM) assay and the loop-mediated isothermal amplification (TB-LAMP) test, together with conventional tools including microscopy and phenotypic culture and DST.
The 4 algorithms, which are illustrative and must be adapted by countries to the local situation, include:
