Hi! I'll enter the new member forum eventually - I have some privacy concerns and don't want to say a lot about myself on the internet. However, I have a question that maybe someone here can answer: What does it mean to have a positive PR3 antibody test (2.7 on scale where less than 1 is normal) and yet the anca screen evaluation for p, c and atypical is negative. Thanks so much for any help.
