Scientists have created a portable, low-cost “lab-in-tube” assay capable of diagnosing tuberculosis (TB) within hours using respiratory or blood samples. The device detects TB biomarkers with 98% accuracy, even in resource-limited settings. Its affordability and portability make it ideal for remote areas where traditional lab infrastructure is lacking. Early trials in sub-Saharan Africa showed a 50% reduction in diagnostic delays, potentially curbing TB transmission. The innovation could save millions of lives annually by enabling timely treatment and reducing healthcare costs.
