I am bumping this ... maybe someone who has experience will be ablke to give you some advice...
So many different factors can affect the kidney function... environmental , food ... i mean bad food ( like the recalled foods a while back) , poisoning... and yes, genetic ... but also congenital, these are 2 different things...
If your baby is fine i am sure you have no reasons to be freaking out right now, but of course it is better to have him checked out just in case, i would assume a blood work will be the first step...
I am wondering what kind of benefit the DNA test would be... are you that is what the vet suggested? The biopsy i am sure will show if kidney is functioning well at the cellular level and more....
Good luck !!!!!! Hope your baby is just fine !!!!
