I think I might have asked this somewhere b4 but I can't remember where or what answer I got and I haven't the strength to search back through...
When I was first diagnosed with ITP 12 years ago, long b4 any of my symptoms started, the doctors tested my ANA the old way.
The result was 15 iu/ml.
I know this result is positive because the reference range is 0-7 but was just wondering how significant a positive if anyone knows?
