I had a few of my labs come in.

My BUN was higher than normal.
My sed-rate (which usually stays at like, 4) was 28
My Anti dsDNA (which i had no idea what it was) was 117.8 when the normal range is anything below 30.

When i googled about this, everything was pointing to Lupus Nephritis and it said that when you have a high anti dsdna, you have to get a kidney biopsy.

I have an appointment on the 16th with my rheumy to go over the results, and i'm scared he is going to tell me that i have to get one.
Has anyone ever gotten a kidney biopsy? If so, what is it like?
