They may be able to get it from his hands as well, make sure he's FULLY hydrated so they can find a nice vein on back of his hand.
I've only been able to have a blood draw 1x on my inner arm, it's actually very hard for most ppl to find a vein.
So they go with my hands, sometimes the veins roll and sometimes they are small but if it's a good tech, they'll find one!
