The World Health Organisation (WHO) has endorsed, what it says, is a revolutionary new way of diagnosing tuberculosis. The test can be done on the spot in 100 minutes compared to the weeks and months it has traditionally taken in a highly equipped and secure laboratory. The new technique has been co-developed by scientists in the US, Geneva and a drug manufacturer. It is expected to help save many of the 5,000 people who die every day worldwide from the treatable lung illness. WHO head of TB diagnostics Dr Karin Weyer said all countries are being urged to roll out the technology, including Australia. The new test is revolutionary in several ways, she said.
