i forgot what it is, but a tb test is to check for tiberculosis...i think thats how its spelled
some sort of liquid is injected under the patient's skin....there will be a little bump there, a bubble of liquid under the skin....the next day the patient comes back. you feel the skin, if you feel a bump, then they have tiberculosis, if not then the person is healthy.....
i think thats what it is...i remember i had to get this for my job
