Doctors Explain Who Needs Lung Function and Tuberculosis Screening
Doctors say healthy people without symptoms usually do not need routine lung tests.
Testing may help people with a long-lasting cough, wheezing, or trouble breathing.
Smokers may also be more likely to benefit from testing.
Doctors may consider lung tests before major surgery in people over 60.
Tuberculosis screening is not usually done for everyone.
It is more relevant for people who had close contact with someone affected or who face certain exposure risks.
Some medical or immune conditions can also make screening important.
Symptoms such as a lasting cough, fever, night sweats, weight loss, or coughing blood should be checked by a doctor.
Routine lung function testing is generally unnecessary for healthy people without symptoms.
People with prolonged cough, wheezing, breathlessness, or a history of smoking may benefit from lung testing.
Lung tests may be considered before major surgery for people older than 60.
Tuberculosis screening is generally risk-based rather than universal, including for close contacts and exposed workers.
Persistent cough, fever, night sweats, unexplained weight loss, or coughing blood warrant medical evaluation.
