Hi John,
Please help me understand the reports I have. The FEV1 column has two numbers. On my last PFT on 4/21/08, the column marked "Meas" said .67, the column marked "% Ref" said 34%. The PFT prior to that was 2/9/06, reads in a different way by rows, the FEV1 rows says Ref 2.01, Pre Meas (0.59) Pre % Ref (29), Post Meas (0.74), Post % Ref (37), Post % Chg 25. The parenthesis are on the test report. Can you help me dicifer this? It's very hard when different criteria are used on the tests. Thank you, Conni
