What is a pulmonary function test?

The effectiveness of the lungs is determined by a pulmonary function test. The test evaluates lung volume, capacity, gas exchange, and rate of flow, as well as other lung-related characteristics. Your doctor may be able to identify and treat some lung diseases based on the results.

How are pulmonary function tests performed?

Pulmonary function tests can be performed in two ways, depending on the information your doctor needs. In some cases, your doctor may request both tests since they measure different things. To evaluate your breathing, your doctor may use a spirometer (a device with a mouthpiece) or have you stand inside an air-tight box that resembles a telephone booth.

What does a pulmonary function test measure?

A pulmonary function test evaluates several elements of lung health. Here are a few examples:The volume of the lungs when they are entirely full of air is known as total lung capacity.The amount of air you can forcefully expel once your lungs have been completely filled is known as forced vital capacity.After you've expelled as much as you can, the amount of air left in your lungs.Functional residual capacity is the quantity of air left in your lungs after you typically exhale.

Great discreet service, scheduled my visit and paid for for the test online not in Showed up at lab, checked in and was seen within minutes. Blood and urine were collected, test results came back quickly within 2 days because I did my test on a Friday. Quick, easy and cheap. Didn't have to wait for a visit to my PCP, and then get referral to lab.
