My spirometry result are fvc 78% fev1 82% fev1/fvc 109% what does it mean ?

Spirometry: If your Fvc and fev1 are within normal limits then most likely your test is normal. In general, level is considered abnormal if it's at least below 75 percent. Ratio of Fvc to fev1 is slightly increased but in the setting of others being normal there is no reason to worry.

Test interpretation: This test should be interpreted in the context of your history. Since you have normal airflow in the larger airways, I would recommend checking the smaller airway function values, and repeat testing. There is a range of normal values, and your own best value may be determined upon repeat testing.
