New tests speed up diagnosis of TB drug resistance

Three new diagnostic tests were found to dramatically cut down the time it takes to identify TB drug resistance, potentially saving lives, according to a new study. While traditional drug-susceptibility testing can take between 21 days to three months, the new tests took just between five to 15 days to complete.

Researchers from the University California in San Diego, USA, said it was important to spot the drugs to which the TB bacteria are sensitive or resistant as quickly as possible. This means that patients can be given the most effective treatment as early as possible.
