hi all

im in turmoil here , for the last 4 months I have had a skin rash itching burning stinging, spreading all over parts of my body.
I went to see my dermatologist who first said it was intertrigo , he gave me creams which didn't work , then I went back and because I have rabbits for years he done a RAST test it came back positive grade2. but he said still no need to remove rabbits as it was only a low grade , by this time my head has been going round and round I researched everything and thought I got everything ,, then the dermatologist sent me for a skin biopsy , and I still don't know what he is looking for
does anyone know what they test for in a skin biopsy ...its been 3 weeks now and I have no results ,, the only results I have are
ANA=weakly pos
dsDNA and ENA negative
white /red blood cells negative
liver/kidney normal

I was told if the dsDNA and ENA are negative then that rules out lupus???

I hope someone can shed some light on what they do in a biopsy and what they are looking for

many thanks
