i definetly wouldnt let some test give you any pre concieved notions about your abilities or lack therof. we all just have to do our best and thats all we can do, but dont let some weird geneticist nocebo you.
If i were you, i would do my best on work days to maintain, and then plan on pushing it (increased volume and intensity) on the days you are home. those are the days you will set your PRs.
You can in fact lift every other day, because hundreds of thousands of people have done it successfully, some of them no doubt with your astonishing odd genetics. You can't lift every other day if you do it wrong, don't eat enough, don't sleep enough, and if you miss workouts so that you're not in fact training every other day. At 5'7" and 175, you're still very underweight, and this interferes with progress.
How much money have you spent with the genetics people?
