Hello Debora and welcome
Are you having any of the symptoms of lupus that you have asked for this test to be done?
Lupus can have a genetic element but is not strictly speaking hereditary so unless you are showing symptoms of having lupus the blood test would be less than worthless, especially as you may have a slightly raised ANA due to being the child of someone with lupus. A lupus diagnosis cannot be given on blood tests alone.
Obviously, with a family history of lupus, you will be more aware of any signs or symptoms and if you start suffering from them may find it worth seeing a rheumy.
I have just reread your previous posts and you think you may have some mild signs of lupus. I think the question on whether you go to see a rheumy or not all depends on how severe those symptoms are. If the symptoms are very mild and not really affecting your quality of life then you are unlikely to be taken seriously by a rheumy who would also be unlikely to be able to give you a diagnosis.
However, if the symptoms are more severe then a GP would not usually have the experience necessary to run the correct blood tests or piece together the weird and wonderful symptoms we get.
I hope I've been clear, that seems a bit garbled...rather like my brain I fear :lol:
