Where can I get a tuberculosis test?

Recently, I've been coughing more frequently.
I need to undergo a tuberculosis test because I am not feeling well.
I think I might do it.

But I don't know where I can get a tuberculosis test.
If anyone knows, I would appreciate your advice.

1. Can I get tested at the public health center?
   Since the public health center is the closest place, it seems convenient, but I am wondering if I can get a tuberculosis test. Also, I would like to know how much the test costs.
   
   

2. What is the procedure for undergoing a test at the hospital?
   I want to know if I can get a tuberculosis test at a general hospital or clinic, and which department I should visit. I'm worried that the test might be expensive.
   
   

3. Can I get tested at my workplace or school?
   I regularly get health check-ups at work, but I'm not sure if tuberculosis testing is included. It would be really great if I could get tested at school or work.
   
   

4. Where is the tuberculosis specialized center?
   Has anyone had a test at a tuberculosis specialized center? I would feel more reassured if I could receive a professional examination, but I don't know where it is.
