I'm in the process of being diagnosed with asthma... but there seems to be a lot of differing ideas around what my peak flow should be. One says 440 and one was 485..
I'm 5"6', female, white, 24 year old .. my peak flow is averaging at 340 at the moment, but sometimes gets up to 390/400. Lowest was 270. Just not sure what I should be comparing it to??
