i have read your query and i would like to mention here that a positive ppd test is a very non-specific test for tuberculosis
. it indicates exposure to the bacilli, recent or past, but it doesnot indicate infection.
so as for now just dont worry and wait for your chest x-ray report. must get a sputum for acid fast bacilli done, in case x-ray has a lesion. you can surely go for work this weekend. if possible, use safety measures like face masks at work, as it protects against droplet infection.
wish you good luck and a good health
