A gas transfer test measures how your lungs take up oxygen from the air you breathe. The result of the test is called the transfer factor, or sometimes the diffusing capacity. A gas transfer test is sometimes known as a TLco test. TLco refers to the transfer capacity of the lung, for the uptake of carbon monoxide (CO).

After you have your spirometry test, your doctor compares your test results to the normal, predicted values from people who are similar to you in age, height, weight, gender and ethnicity.

What are normal values for pulmonary function test?

Normal values for PFTs vary from person to person. The amount of air inhaled and exhaled in your test results are compared to the average for someone of the same age, height, sex, and race. Results are also compared to any of your previous test results. If you have abnormal PFT measurements or if your results have changed, you may need other tests.
