Researchers at the University of Pretoria have developed a handheld device that could significantly improve tuberculosis (TB) detection.
The tool, known as MARTI, uses just a drop of blood and delivers results in about 30 minutes, avoiding the need for sputum samples and lengthy lab processing that can take days or weeks. It works by detecting antibodies that show the body is actively fighting a TB infection.
Experts say the device could help reduce the large number of undiagnosed cases—TB killed over 1.2 million people globally in 2024—and improve screening in high-risk settings like prisons and mines. The innovation may also lower transmission risks and ease the economic burden caused by delayed diagnosis.
