The first time I got set up with the machine, in Virginia, I had to sleep all night with wires stuck on everywhere leading to a recording device. It generated the info needed for diagnosis, so I didn't have to do the sleep-in test, which would have been necessary if the at-home test didn't work. More recently, getting set up with a new health provider here in California, I had to do the in-home test again. This time they provided a machine with a SD card. The machine tracks your breathing through the air tube. There was one sensor that fit on a finger, with a bright little light in it. All the info was recorded onto the SD and that was used for diagnosis. The first time the mask fit badly so the test didn't work and I did it over again with a different mask. I was told that if it didn't work the second time, I would have to do the sleep-in procedure. So, bottom line, there must be several different ways to do this.
