If you notice clubbing, call your health care provider.

What to expect at your health care provider's office:

A person with clubbing usually has symptoms of another condition. Diagnosing that condition is based on:

• Family history
• Medical history
• Physical exam that looks at the lungs and chest

Medical history questions may include:

• Do you have any breathing difficulty?
• Does clubbing affect the fingers, toes, or both?
• Is it becoming more noticeable?
• Is the skin ever bluish-colored?
• What other symptoms do you have?
• When did you first notice this?

The following tests may be done:

• Arterial blood gas
• Chest CT scan
• Chest x-ray
• Echocardiogram
• EKG
• Pulmonary function tests

There is no treatment for the clubbing itself. The cause of clubbing can be treated, however.
