Hi, rainbow.
I am a 39 years old woman in South Korea and I also have High anti-centromere without any symptoms, but only Raynaud's. I got a high level of ANA such as 1:1280 in 2015 and 250 anti-centromere.
I have been worried about my health since my doctor sent me to a big hospital in Seoul. I had various blood tests there recently and have been waiting for the result.
Thanks for sharing your experience. It is very helpful and a hopeful news to me.
