This New York Times article details the results of a new automated test for drug-resistant Tuberculosis which gives quite accurate results in 2 hours instead of four to eight weeks. This new machine will come as a great help to those diagnosing and dealing with TB on a frequent basis, as it will help doctors in deciding to start treatments earlier.
However its drawback is the cost “machines cost $30,000 and each test is about $60”. So the populations who might probably need it more in poorer countries will either not have access to this machine, or have to rely on the goodwill of others to get access to it. This machine like many other new and effective diagnostic equipment and treatments will definitely be useful albeit hard to integrate into global health systems, but it is one step in the right direction.
