TB Or Not TB????

I got a call Saturday saying that my Grandpa has tuberculosis. Bad disease. Really contagious. All the little kids in the family were alerted to be tested. Researching on the internet says not just children but elderly, pregnant women (not me, a cousin), and people with weak immune systems. Mark has been a bit sickly, so everytime he is around someone sick, he gets it too. Well, Mark has been on the other side of the country. Not much he could do. He still had to come home. If he told the airline people he had been exposed, they might not have let him fly. So I chose not to say anything to him. No reason to spoil his fun. So today I called the Health Department to set up an appointment for our family to get tested. They took my name, number and all that and told me to come in tomorrow. Then later I get a call saying the lab people got Grandpa's results mixed up with someone else's. So after most of the family has already been tested and received their negative results, we find out there is no need. Wow, hope we never have true medical emergency.
