Hello! I'm Dr. Smith, a pulmonologist with over 15 years of experience. I specialize in diagnosing and treating lung conditions, and pulmonary function testing is an essential tool in my practice.

The time it takes to get the results of a pulmonary function test (PFT) varies depending on several factors:

* The complexity of the test: Simple PFTs, such as spirometry, which measures lung capacity and airflow, can be analyzed immediately after the test. The results are usually printed out or displayed on the screen during the test itself.
* The type of test: More complex PFTs, such as diffusion capacity (DLCO), which measures how well oxygen moves from the lungs into the bloodstream, require additional calculations and may take a few days for the results to be available.
* The laboratory's workflow: Some laboratories may have a faster turnaround time than others, depending on their workload and staffing.
* The reason for the test: If the results are needed urgently, such as in the case of a patient experiencing respiratory distress, the lab may prioritize the analysis and provide the results sooner.

Here's a breakdown of the typical turnaround times for different PFTs:

* Spirometry: Results are typically available immediately after the test.
* Lung volumes: These tests usually take a few days to analyze, as they involve more complex calculations.
* DLCO: Results are generally available within a few days, but sometimes can take up to a week.
* Bronchoprovocation testing: These tests, which involve inhaling substances that trigger airway narrowing, can take up to a few weeks for the results to be available. This is because the results may need to be analyzed by a specialist who can interpret the complex data.

It's important to note that the time frame for receiving the results can be affected by factors outside the laboratory's control, such as weekends and holidays.

In general, you can expect to receive the results of your PFT within a few days, but it's best to check with the laboratory or your doctor for specific information.

Let me know if you have any other questions. I'm always happy to help.

The average PFT takes about 45 minutes to complete. However, testing time varies depending on what the doctor requests. In most cases, the doctor will review the results with you upon completion. There is usually no after affects from the PFTs.read more >>
