TB or not TB
That is the question.
Whether 'tis nobler to suffer the slings and arrows...
Ok, enough butchered Shakespeare
Grandma had it. We all had to get tine tested. Basically you are exposed to PROTEINS unique to TB and if you have ever been exposed to TB, you will show a positive.
Next step is the chest radiographs. TB forms tuberecules in the lungs which are calcified depots of the TB bacteria. When your immune system is working, the bacteria wall up in their tubercules but get sick and they come out, eventually killing you.
If you are positive on tine but negative on the radiographs, you might still have to go on antibiotics. But a double positive means antibiotics plus a face mask and warnings to completely take ALL meds.
There are some nasty strains out there.
