The fastest way to detect TB is using nucleic acid amplification (NAA) tests. These tests amplify DNA and RNA segments to rapidly detect Mycobacterium tuberculosis DNA in specimens within just hours.
While traditional methods like the TB skin test and chest X-rays can take several days to weeks for results, NAA tests provide quick and accurate diagnoses, enabling prompt treatment and preventing further transmission.
However, it's important to note that the availability and accessibility of NAA tests may vary depending on location and resources.
