wow, first thing I thought was you should change your doctor. The way he/she is looking into giving you a definite diagnosis or their actual thoughts on your having lupus is defiintely not the way to go about things. This is not the way you should be assessed at all, as it is not the 'usual' way to look at a diagnosis/relevant criteria in assessing whether or not you might have lupus. Blood tests alone do not determine a diagnosis in regard to having lupus.
There are questions that have to be asked. Most importantly is about your past medical history. Any symptoms should be looked into and taken into account. It is this history of symptoms that will help determine whether or not you meet the criteria laid down to give a definite diagnsosis of lupus in any of its forms. A reputable rheumatologist would have asked about your medical history, how you feel now and how you have felt for 'X' number of years. Lots more questions should follow and be answered by the patient. It should not be just the outcome of blood test results.
Is this a 'proper' rheumatologist? If not, please try to change to someone who knows what they are talking about, difficult I know to change doctors in the UK but try your best if you can. You need a good understanding rheumatologist who can do appropriate testing and who knows what they need to be asking you.
Sorry If I sound a bit harsh but I am so annoyed that some doctors are dismissive of their patients and just think what they say has got to be accepted. You are the patient and you have the right to ask and ask questions if you are not satisfied with what you are told. It is your body when all said and done.
Hope what I have said reads ok and makes sense. I have edited and re-edited it so many times. I have got a bit of a cotton-woolley type brain at the moment.
Take care. Please pm me if you need to.
