I need to consult with Infectious disease specialist

Customer Question

Hello. I need to consult with Infectious disease specialist (regarding TB test/Quantiferon criteria)?

Customer: replied 10 months ago.
After both tests came as positive I was prescribed antibiotics for 6months (isoniazid300mg) . I was told I don't have a disease but was exposed and do have a latent bacteria somewhere hidden in my body that needs to be treated as a precaution. My question is : since I was BCG vaccinated , is it possible that Quantiferon test is positive because of that? To me it kinda make sense. However I don't really understand the Quantiferon criteria and that's why I am here asking for your opinion
Expert:  Dr. Phil, MD replied 10 months ago.
Thanks for this questionDo you have any other medical issues?
Customer: replied 10 months ago.
No. I was a proffesional tennis player all my life , I am in a good shape and exposed to lots of physical effort
Expert:  Dr. Phil, MD replied 10 months ago.
No, this is not possibleThe quantiferon is not made positive by BCGThe normal TB skin test is thoughThat is one major benefit to quantiferon
Customer: replied 10 months ago.
Ok.
I would like to know whether it is absolutely crucial to go on this pill for 6 months considering the fact that my Quantiferon blood test is considerate as "low positive ". I guess my question is how relevant and important is it to do this treatment and what is really the procentige of risk factors of me actually getting the disease ? My Ag minus Nil Value is 1.18 and from 0.35 to 2. is considered at the low end of the positive range.
Expert:  Dr. Phil, MD replied 10 months ago.

Expert:  Dr. Phil, MD replied 10 months ago.
