I've had severe cough on and off. Need help in deciphering the results.

I've had severe cough on and off for the last year and a half. Four months earlier, episodes of cough exacerbated with fever and sore throat on and off. Cough episodes ensued retching and nausea. Cough was initially dry but later had sputum in it. I had my ESR done around that time and was came out elevated along the lines of 70s. The cough episodes and fever eventually subsided. Visited a pulmonologist about a month ago for the prior complaints with my CXR done. The pulmonologist suspected obstructive diseases and suggested spirometry and IgE levels. The results came out today and are as followed: pre-FVC is 2.71, pre-FEV1 is 2.67, post-FVC is 2.71, post-FEV1 is 2.64. IgE is 341 IU/ml. Kindly elaborate what these findings suggest. TIA.

Hello and welcome to MedHelp's forums.  I'm glad to hear you are working with your doctor to understand what is happening with your breathing and the cough.  Your doctor should meet with you to fully explain your results and that is best place to get your information.  Please schedule that appointment.  In the mean time, here is an overview of spirometry testing https://www.webmd.com/lung/types-of-lung-function-tests#1.  As to the results you've listed here, normal values are dependent on age, gender, race and height. Here is a calculator that you can input your information that is provided by the CDC that may be helpful for you https://www.cdc.gov/niosh/topics/spirometry/refcalculator.html
Once the FEV1 drops below 70 percent of the FVC, the diagnosis of COPD is made.

Please input your values into the calculator and let us know what the outcome of that is.  

When is your follow up with your doctor?
