Something like 1/3 of the world's pop has been exposed to TB.


and with Air Travel , globalisation, and immigration what is a problem in one part of the world is a PROBLEM IN EVERY PART OF THE WORLD.

Look at the global concern of Avian Flu.

there should be equal global concern re TB.

There are only 3 recognised diagostic tools for detecting TB

(1) TST....Tuberculin Skin Test.....US based.
It is around since 1910. It is a two step test. It is invasive , especially in some cultures and in some cases downright unreliable.

(2)QuantiFERON
It is Aussie...so it has to be good

"The first application of the technology is for the detection of tuberculosis (TB) in humans, which will potentially replace a less accurate and cumbersome test that has been in use for over 100 years. Cellestis' product, QuantiFERON-TB , has been approved for use and sale by the US Food and Drug Administration (FDA).

(3)T-SPOT TB

UK based. A blood test.
It is expensive and inflexible.


I have bought my first CST shares....$3.20.
