The test, called Xpert MTB/RIF Ultra, allows you to quickly and accurately identify markers of the bacterium that causes tuberculosis in patients' saliva. It works on the basis of molecular analysis and gives results in just a few hours.
In addition, the technology can identify genetic mutations associated with resistance to major anti-tuberculosis drugs, which helps doctors choose alternative medicines.
The new test has received the status of "prequalification" by WHO. This means that it has passed rigorous testing and can now be used in tuberculosis control programs around the world. According to WHO representative Yukiko Nakatani, technology will become an important tool to save lives and prevent severe forms of the disease.
The test is intended for patients with suspected tuberculosis who have not yet started treatment or have been treated for less than three days in the last six months.
WHO is currently evaluating seven more similar tests to increase access to modern diagnostic methods.
