I recently received the report for my PFTs and wanted to ask what the column headings mean:
"Ref" is reference?
"Pre meas" is that predicted measurement or does the "pre" stand for before?
"Pre % Ref"
"Pos % Ref"
"Post % Chg"
I will meet with the pulmonologist, sure, but meantime, I wanted to get a headstart on deciphering my results. Thank you!
