The test results were things that could indicate poor kidney function.
A creatinine of 1.3 with the "normal" range being no higher than 1.1 is not an indication of poor kidney function. It may reflect nothing more than dehydration at the time of the blood draw.
Stop assuming that the ER failing to assess your sister needing future dialysis is an indication of malpractice.
Hopefully her need for dialysis will be short term and kidney function will improve. That is, if she discontinues her use of street drugs.

Yes, OP seems to fail to consider that the sister might have been using during those 2 weeks.
I realize that OP cares deeply about the sister, but OP's anger is misplaced. Energy would be better spent figuring out how to get this self destructive young woman some help.
