What is the TL,CO Task Force?
The TL,CO Task Force is a joint ATS/ERS project which proposes to build upon the success and expertise of the GLI Spirometry Task Force by expanding our work to include new reference values for the measurement of the transfer factor for carbon monoxide of the lung (TL,CO).
Why do we need TL,CO reference equations?
The 2005 ATS/ERS PFT guidelines provided updated standards for the measurement of TL,CO and an interpretation flow-chart showing the vital importance of TL,CO for interpreting PFTs. At this time no consensus was reached regarding which equations should be recommended. The development of international measurement standards, with corresponding changes in equipment, software and measurement techniques, combined with shifts in population characteristics, means that some TL,CO equations may no longer be appropriate. The use of inappropriate reference equations can lead to serious diagnostic errors, with its associated burden in terms of financial and human costs.
Members of the GLI TL,CO Task Force:
How to contribute data:
If you have measured TL,CO in more than 100 healthy subjects please consider contributing your data to the GLI TL,CO Task Force. To contribute data please visit http://www.gligastransfer.org.au/ to register your data for the TL,CO project. A member of the task force will contact you with further details.
