Guys, I have new problem. I have rheumatoid arthritis, I'm taking methotrexate for the last 4 years and I'm going to move to Humira. I've just received my blood results and I am positive to quantiferon!!!
When V had the similar exam, the result was "indeterminate", he did TB-spot (which was negative) before the start of the medication (azathioprine at first). Do you think that there is high possibility for him to be positive too??? How reliable TB-spot exam is?
