anyone ever had bloodwork show low protein?

Had no idea that low protein could be detected like that. Rather than supplements, I would look at eating more high protein real foods. Some things that come to mind are eggs, tuna and salmon, introducing more grains (eg switching to multigrain bread) and looking for high protein vegetables like corn, peas, squash, mange tout etc. Here's a couple of lists that might help.

Eggs, cottage cheese, peanut butter, and Greek yogurt are easy ways to get protein.

I have low protein that shows up on blood work.Doctor doesn't seem to think it is something to worry about and perhaps is related tomy kidney issues

Low protein is extremely rare in the USA. From what I read a few days ago, adults need 45 units (might have been grams) of protein a day. Most people get 90 grams of protein a day. Vegans get 70 grams of protein a day. 

What you need to worry about is excess protein because that can cause many more health problems than too little. 

I wish I could find that piece I read this from (if I can I'll come back and give this more clarity). 

A lot of traditional doctors and the general public here in the USA think "protein, protein, protein" as if it's the most important nutrient our bodies need. It's not. It's that we've been brainwashed from meat producers to think this way. What a lot of the general public in the USA need is fiber. Most of us barely get enough fiber. We eat white rice, white spaghetti noodles and bread that's had the fiber taken out. We get into "juicing' thinking it's a healthy thing to do, and it's not! Because what you are throwing away is the fiber of all those veggies and fruits you are juicing. 

As far as grains go, it's important to eat whole grains. It has to say the word "whole" on the label. Multi grain means nothing, except more than one grain, but those could be stripped grains. Whole wheat spaghetti noodles, whole brown rice, bread that is "whole wheat". 

Anyway, that's what this article was about. I wished I remembered why too much protein is bad for you. I'll see if I can find that article tonight or tomorrow. 

As far as you OP, firstly I wouldn't do anything. Secondly, I'd research to see if you can really test your protein levels on one blood test. And remember blood tests aren't 100% accurate. Nothing is. Third, if it is possible to have protein levels tested this way, ask to have the test repeated when your insurance allows it. 

It's the albumin levels they're probably referring to, and yes that's standard in a chem profile done on most patients yearly after a certain age.

Eating too much protein can tax your kidneys, but you'd really have to be eating/supplementing with a LOT of protein for that to be an issue in a typically healthy person.

And since her levels show a low protein, that's not something she needs to be concerned about. She may need to be concerned about why they're low, as in an absorption problem or kidney problems. Extremely low protein causes kwashiorkor, which you see on malnourished children when their abdomens ate greatly distended. That's the far other end of the spectrum, though. If I was OP I'd try what's easiest first, and that's increasing her intake.
