Thought I would post this as a new thread.
Those in professions where TB testing is required/pushed, esp. those opposed to submitting to the injection of biologicals/chemicals into their body, might be interested.
Wondering how long it will take for this to make it to the US/be more widely available and accepted. (if anyone has any more recent info on this, I would be interested!)
While still invasive, a blood draw is MUCH less invasive than a subcutaneous injection OR a chest x-ray!
New TB test

CAMILLE FUNNELL: Scientists in Britain have developed a blood test to identify tuberculosis in its earlier stages before any symptoms of the disease become apparent.
The current test for the disease now used in Australia is more than a hundred years old and is considered unreliable because it can give false positive results in people who have been given an anti-TB vaccine.
Edmond Roy reports, while a new test has been developed, it will take at least three years before it's widely available to the public.http://www.bioportfolio.com/news/Oxford_Immunotec_1.htm
“Oxford Immunotec launches revolutionary T SPOT-TB blood test
12th August 2004. …a revolutionary new blood test, T SPOT-TB, has been approved for use in Europe and gives real hope that the tide can be turned in the fight against the disease.
Oxford Immunotec's new test is set to replace the century old tuberculin skin test, the oldest diagnostic test still in use today. The launch of T SPOT-TB is a key milestone in mankind's fight against this ancient disease and will bring TB care out of the Victorian era and into the 21st century.
T SPOT-TB enables doctors to reliably screen people who have been in contact with a TB sufferer, allowing those who have been infected to be identified and treated long before they actually develop the disease and become infectious to others.1,2 It provides an accurate and effective tool for controlling the spread of TB.3
The T SPOT-TB blood test is easy, rapid and accurate. Crucially, it is the first test that reliably detects infection in people with weak immune systems,4 including new-born babies,5 people with HIV6 and transplant patients, precisely the people who are most vulnerable to developing full-blown TB.
T SPOT-TB represents a dramatic improvement on the existing skin test, which is crude and unreliable. The skin test is prone to both false-positive and false-negative results and previous BCG vaccination makes it inconsistent. It is also inconvenient, taking 3 to 7 days before it can be read, and it can cause painful blistering and scarring of the skin."
