What is an abnormal FVC?

Restrictive lung diseases can cause the FVC to be abnormal. This means that the lung is restricted from filling to its normal capacity of air. Asbestosis (scarring of the lung due to asbestos exposure) is an example of a restrictive lung disease.

What is FVC for lungs?

Forced vital capacity (FVC) is the total amount of air exhaled during the FEV test. Forced expiratory volume and forced vital capacity are lung function tests that are measured during spirometry. Forced expiratory volume is the most important measurement of lung function.
