Lung Function Test

Overview

Lung Function Test (a.k.a. Pulmonary Function Test) is a variety of test to determine how well your lungs work. The most basic test that is given is spirometry which is a test to measure the rate of airflow and lung size.

What Facts?

Lung Function Test (a.k.a. Pulmonary Function Test) is a variety of tests that would measure how well your lungs work including spirometry and lung volume tests. All of tests are conducted to diagnose lung and airway diseases, comparing the lung function according to its expectations and to monitor whether the treatment is working.

Relevance

Lung Function Test is used to test you lungs for doctors to diagnose lung diseases such as:

  • Asthma
  • Allergies
  • Chronic bronchitis
  • Chronic obstructive pulmonary disease (COPD)
  • Damaged or scarred lung tissue

  • Lung cancer
  • Infections
  • Thickened, stretched, or enlarged airways
  • Thickening or hardening of your connective tissues, known as scleroderma
  • Weakness of the muscles in the wall of the chest

With the Lung Function Test, the doctor may get a precise diagnosis to assign the right treatment. These tests is the first thing that is necessary to be done in order to treat lung diseases

Blood draws are routine procedures and rarely cause any serious side effects. However, the risks of giving a blood sample can include:

  • Pulse Oximetry : This test will estimate oxygen levels in your blood.
  • Arterial Blood Gas Tests: This test will measure the level of gases such as oxygen and carbon dioxide in your blood taken from one of your arteries.
