2yrs ago started w/ joint pains, rash on and off , anemia. ana test 1:40 speckled , crp 6 .0mg/l, rf was normal , previous dr said it could be lupus .?

Tests: These tests need monitoring but cannot establish a diagnosis. You need to have them followed up if your joint issues continue to occur. See a rheumatologist.

Lupus : If your symptoms are persisting, check ANA again with titers and if ratio is strongly positive (not 1:40, but like 1:80, 1:160, 1:320, 1:640, etc) than certainly other serological tests for lupus can also be performed and lupus diagnosis can be entertained. You need to have 4/9 criteria to say it is lupus.
