Alexanders,

Your quote "Now the Research Institute of TB in Japan thinks the gel in the tube gets soft in hot weather, breaks off, stimulates the blood cells and gives false positive results."

Just wondering what period you are referring to here given that the resupply of QFT IT into JAPAN after the severe shaking incident didn't occur until late last year and early this year. During that time the season was Winter and now into Spring. Hardly when one would expect the weather to be hot and impact on the tube gel.

cheers
