SOUTH AFRICA: New technology could revolutionise TB diagnosis

JOHANNESBURG, 31 December 2009 (PlusNews) - A new technology being pioneered in South Africa may make screening for tuberculosis (TB) faster, cheaper and more reliable – and it’s all based on technology found on a typical trip through airport security.

The new computer diagnostic system known as TBDx takes digital pictures of sputum samples and searches them for TB’s structural “fingerprint.” Some airport scanners work in much the same way, searching luggage for the structural fingerprints of plastic explosives, for example.

The system is being pioneered by health research organisation, the Aurum Institute in partnership with South Africa’s National Health Laboratory Services (NHLS) and imaging specialists, Guardian Technologies International, and is the first in the world to pair advanced imaging technology with a digital microscope.
