Heel prick test borderline?

Hi ladies!!!! So my baby girl will be a month old on friday!😍 and when she was born they did her heel foot prick test and one of the tests came back borderline. I don’t know the test name but it’s the one that deals with protein(not really sure if this helps). I’ve googled it and all google does is scare the hell out of me lol have any of y’all dealt with this? I also wanna say that she’s been put on Similac Alimentum to help her gain weight cause the first 2 weeks after she was born she lost almost a pound and the doctors were worried.

Here’s some pictures of her cause she’s got me wrapped around her finger😍😍😍
