Researchers have developed a portable device called MiniDock MTB that can detect tuberculosis (TB) from tongue swabs in just 30 minutes at a cost of $4. This test received official endorsement from the World Health Organization (WHO) in March, marking a significant advancement in TB diagnostics, especially for low-resource settings. Traditional methods, like smear microscopy, often miss a substantial number of cases, particularly in vulnerable populations who cannot provide phlegm samples. The MiniDock MTB test has shown an accuracy of 86% for TB-positive phlegm samples and 80% for tongue swabs, outperforming smear microscopy by 24%. The device operates on a power bank and is designed for use in rural clinics and community health posts. While it is effective, it does not currently detect drug-resistant TB, though further developments are underway. This innovation aims to enhance TB detection rates and provide timely treatment for millions who remain undiagnosed.
