Why Test for NTM ?

Lung x-ray

If you think you or a loved one may have NTM lung disease, there is something you can do. Talk to your doctor or a specialist about your symptoms and any lung conditions you have. Ask if getting tested for NTM lung disease may be right for you. The Doctor Discussion Guide below can help you ask the right questions.

It’s important to get tested for NTM lung disease because NTM—and its most common form, MAC lung disease—can worsen over time, causing more damage to your lungs. Your symptoms can get worse too.

Since the symptoms of NTM lung disease are similar to other lung conditions, diagnosis can be delayed. Many people who have NTM may not know it for months—or sometimes years. In fact, 2 out of 3 people with an NTM infection have moderate to severe NTM lung disease by the time they're diagnosed.

NTM lung disease causes damage to your lungs that will only get worse with time.

Getting tested is the first step to being properly diagnosed. The sooner you receive a diagnosis, the sooner you can begin to evaluate your treatment options with your doctor.

But starting the dialogue isn’t always easy. Visits may be short, and it can be difficult to remember everything you want to say at an appointment.

Diagnosing NTM lung disease can be difficult because the symptoms of NTM are common and can be mistaken for other lung conditions.

If you think you or a loved one has NTM lung disease, ask your doctor if you should be referred to a pulmonologist or an infectious disease (ID) specialist. Pulmonologists and ID specialists are more likely to be familiar with testing for and treating NTM lung disease.

You may want to consider finding a specialist who has experience caring for people with NTM lung disease. The disease can be difficult to manage, and some doctors may have limited NTM experience.
