Not sure if I had the same test, but I've had a test several times (a few years ago) where I had to blow into a container and it registered the lung function. I do remember that I was only about 1/3 of where I should have been! This was during a period of time I get every Spring, when I get asthma-like symptoms, but using an inhaler didn't help. For me, this goes away every Spring, after a few weeks. Not sure what it is!
Hope you get answers!
