Yep, the home tests are available, but have their shortcomings. I was in the sleep lab at the VA and it looked like a NASA control center. Here’s a little blurb on the differences.

“Home sleep apnea tests are generally less accurate than lab studies. Home tests only measure breathing, not sleep, so results can be inconclusive or falsely negative. For example, patients with obstructive sleep apnea (OSA) often breathe through their mouths, which may lead to inaccurate signals. Additionally, you don't have support from lab staff to troubleshoot potential problems.”
