FEV 1 - Pre or Post Meds?

[Blossom/Jackie W.]

I asked my Family Dr about this one time; I'm not sure I agree with her answer.

When a person references or talks about their FEV 1 number; do they use their Pre-med # or post med # since for many the % increases post meds?

What d'ya think?

I think myself I would pre med, however I have noticed a lot of people use post med, with a few that post use both. I feel my true numbers are pre med myself. JMHO Arlene

For me it would definately be pre med.

Hi Every one
I know when I go for my routine plum test they want me not to be using any meds for @ least 12 hr for advair & 24 hr for sprivia & 4 hr albertol.They are mostly interested in my premed #'s

I have never had any of test you all talk about. But , come Monday I believe that will all change. When I ask I was told I wasn't healthy enough. But, Hi Ho I am now. So I will let you all know.

The next time I see my pulmo, I'll ask him. God, I hope it's not the pre. That is about 7% less than the post

The difference is seen as asthma, in NZ they may record both so your asthma component is known, but the best (post) result is the important one.
An example of this is to qualify for subsidized spireva your best FEV1 must be below 40%

[Blossom/Jackie W.]

o.K. ; so what you're saying Larry is that to qualify for "assistance re: Spiriva" it's your "pre" # that's used.

Linda; this has been a question of mine for awhile.

I've never been told I have an asthma component; I have CB & E BUT on my meds (Symbicort & Spiriva) my numbers have changed even more than Linda's.

We throw the numbers around on all the forums but; is it pre or post? Additionally; when it comes to Dr's....is it pre or post?

I look forward to what your Dr says Linda I'm also gonna try and make a note to ask my pulmo Dr as well. Heck; maybe I'll ask the RT at my site. Sheeesh; boy am I slow....

No Jackie I said its your best that is used, thats post med. If after meds my FEV1 is below 40% then you get subsidized spireva.

I know my doctor goes by pre med unless the post med show a large enough increase to indicate an asthma component and that is more than 7%. I just had mine done and that is what I asked about. Anyone have the link to where you can put your height age in and come up with what it should be? thanks Arlene

I will try to inquire too but I have to come back and re-read all this. My brain cannot handle it tonite. My computer is not cooperating and it is late.

I want to know too. If I remember I will look at the test I had. I know what they told me but I don't know which it was.

Jackie; the reason you are slow is because you are moving too fast. Slow down.

[maryaz]

I'm back. Been running little behind. I usually get where I am going but just a lil slow.

My doctor has used the 'Pre'. That is about what most of you said.

Muffin here is the site you wanted I think.
