This is just to find out what molecules are the right size for what sort of extracorporeal removal, if at all. These weights are (mostly) just an approximation, especially as they get into the tens of thousands. Have a go. I found it interesting, hopefully you might, too.

NB: Haemodialysis generally removes molecules <20kDa in size, and Haemofiltration <60kDa. Removability depends on Vd, which depends on protein binding, lipophilicity etc.
