I've been dealing with bronchitis for a few months now, and before that, I was coughing up some thick phlegm. My doctor gave me some meds, but I'm kind of worried and thinking about getting a lung function test just to be safe. Can you suggest any tests that would check lung capacity and function? What are the main tests I should consider for this? Would really appreciate your guidance.

there are pulmonary function test kindly do it
