I wouldn't say it's typical, but it's not altogether uncommon either. There are people that will have two patterns identified at the same time even too! Both of the patterns you've tested positive for...are fairly common among people diagnosed with lupus.
I am wondering why they are bothering to test the ANA after 10 years with lupus? The chief value of this test is in diagnosis, it does not relate to disease activity. Even if the ANA returns to negative, it doesn't mean you've been cured/no longer have lupus.
I reached a point where I told them I no longer wanted it run, b/c I didn't want to have to pay for any part of it when it really did nothing for me anymore!
Hope you're managing well at the moment.
