NOT BE RUDE BUT I WAS WONDERING A FEW THINGS HERE.
1) SHOULD THE TEST BE MORE ACCURATE IF DONE CORRECTLY?
2) WHAT DOES PHYSIOLOGICAL VARIENT MEAN.
I KNOW WHAT THE TEST IS FOR , MY HUSBAND IS AT END STAGES OF EMPHYSEMA. HE HAS ONLY 15 % FEV.
I DONT WANT TO BE RUDE BUT I WAS JUS WONDERING
Hello,
Spirometry is pulmonary function testing which measures the amount of air taken in and exhaled as a function of time. The percentage of FEV1 can help in defining severity. A value is usually considered abnormal if it is less than 80% of your predicted value. This test can give important information on whether or not medications are working, or if your disease is worsening though it has some pitfalls. The normal value ranges may vary slightly among different laboratories. It is best to talk to your doctor about the meaning of your specific test results. Write to me again on how you are doing.
Best luck and regards!
