Note: Predicted FVC should be "race corrected". If the predicted FVC is not already race corrected it should be reduced 12% for blacks or african americans and 15% for asians (multiply the predicted FVC*0.88 or 0.85).
What %Predicted is the FVC?
(Example: if the FVC is 3.86 Liters and the predicted FVC is 4.14 Liters the equation would be 3.86/4.14*100=).
HERE ARE THE LOWER LIMITS OF NORMAL (LLN) FOR FVC
