ANCA in UK/Ireland numbers

I was diag in July 2013 and have just come across ANCA antibody test for that time, with a titre of 320 and anti-PR3 ELISA of 356, said to represent a 90% of people with GPA/WG, how do these numbers compare with everybody else, considering the difference between countries.
Please come back ASAP as I have a consultation soon and need to understand the numbers from real sufferers on this forum.
Many thanks

Not sure about those numbers stephwest but i can report that my ANCA was 750 when i was DX 6 years ago. After my 2 year RTX IV completed in jan this year i am around zero!!
Good luck with your consultation and keep us informed.
