Hi I am 21 years old,I don t have any history of PTB,but when I got my Pre employment Exam Result today, it shows PTB left upper Lobe . I m quite confused, for 3 or 4 times of Chest Exam I've got this Impression: Minimal PTB,Left Upper Lobe . What does it mean? I don t want to loose my job..Can this affect my pre employment Examination? Am I not considered fit to work? Please advice ...Thank so much.
