How can you get on myspace at school my school blocks every wed sitres they already blocked &proxy&?
You cant catch TB via blood or cells so that's fine. Does the lab have no way of tracing the sample back to the recipient to check for HIV? Also, just to clarify, you were handling CELLS, not blood? If this is the case any infection transmission would be extremely extremely low. As you may know HIV tends to reside within lymphocytes so unless there were a bunch in the tissue you were handling, you're fine. Cancer is not contagious either. So don't even worry about that. Any stray cells that entered your body will be destroyed by your immune system pronto. And the cells you were handling were not infected with anything, so even less reason to worry. If you still have concerns talk to your supervisor again, I suspect I wont be able to stop you worrying but really, you shouldnt!
