Hi. I failed my first medical due to my peak flow reading. Is there a min pass reading??? The doctor has told me I need to get a reading of 712. I'm 16 years old and 179cm. Is there a scale for age and height??
Can't find any answers online. I've never had any asthma problems and my own gp seems to think that reading of 712 is high.
Any help appreciated.
