Thanks for your questions.
Dont worry.Anti TB positive dont hold so much importance nowadays if you donot have any symptoms.so please go to a physician to check any signs and sypmtoms of pulmonary and extrapulmonary TB.and dont forget to do atleast a chest xray and routine blood count.
Your urea is normal.
I think you write wrongly it should be CG means creatinine
and that level is also normal.
