I received a TB shot on Monday. I had no reaction from it but the nurse didn't tell me to return in 2 days I returned on that Friday. So now she said she needs to retest me on Monday again. I feel uncomfortable with it.
Hello~I have trying to do some research, and yes, it looks like it can be done that soon. From what I am reading, it appears like 3 days is the longest you should wait to have it read.
