medical examination at medical commission

Can anybody help me here? i had my repeat xray in medical commission coz they found something in my lungs. After that, they performed the ppd on my arm and the result was 9mm. After that, the doctor told me I had to undergo another test which is more reliable than xray and ppd. So I had blood extraction. 10days after, the company I wprked for told me not to go on duty today but they didn't say what the reason is. They told me to wait for a call from the office for one or 2days. Tomorrow is the second day, I am so scared why. My other workmate also underwent the same tests with me and she was told that she will be referred to a hospital. Pls help if u know anyone same with my case. Thanks
