There are extremely short lists of labs you can order yourselves. Virtually all of them are not on those short lists?

I would love to hear of any specific example, I will happily either show you how to order it or learn something myself.

Arterial blood gas. Calcium score (may not count as a lab). Skin biopsy for cancer (does it count as a lab?). I'm unaware how to order my own troponin if I think I've had a heart attack (not that that's one I should DIY diagnosis). Prostate specific antigen.
