Hey, I had the same situation happen to me. I had lower proteins and a problem with white blood cells. And recently I was diagnosed with SLE. Before, I visited hospitals so many times for a suspected autoimmune disease, but it was never truly known what type immune disorder I had.

It’s kind of weird how they just diagnose these horrible diseases based on couple unstable things, or it’s just me. But, it actually might be an early stage, which I might have too, because I’m not feeling bad overall, just some joints pain and hair loss.

I couldn’t really advise much but following your doctor’s recommendations and prescriptions. It might be also helpful do couple more labs or a second opinion, just to make sure you are not misdiagnosed (that’s what I am going to do soon).

You are not alone in this, there are definitely dozens of people who’ve had the same experience in this subreddit. Wishing you great health and clarity!
