After testing I have ANA positive and rnp positive (1.4). What could this mean? ?

After testing I have ANA  positive and rnp positive (1.4). What could this mean? ?

Context: If the titers are both 1:4 and you do not have obvious lupus or mixed connective tissue disease, then i'd bet they mean little or nothing. Diagnosis in rheumatology is based on history and physical exam, with labs just for confirmation. ...Read more

I tested positive ANA and anti dsdna, later testing neg.  I have past diagnosis that may apply to lupus but do not do well articuliatng at dr.  Help?

Tests and lupus: The question is why is the doctor running the tests? If your symptoms and physical signs are a strong indication of possible lupus, positive dsdna helps confirm a diagnosis of lupus. If the tests are run for "screening", they are worthless tests. No diagnosis of lupus or connective tissue disease can be made on antibody studies alone. ...Read more

Is nephrologist good: If the nephrologist is good to go with the results of the tests and what needs to be done then, I would say follow his/her lead. My guess is you've done plenty of tests....time to let your doctors analyze all the tests and come up with a good plan. ...Read more

I lost 65 lbs from march to oct. Hair started falling out in june. I am ANA positive 1:640 spec pattrn. Rheum dr tested for autoimmune. All negative?

Malabsorption: This is malabsorption / maldigestion until proved otherwise. If there's joint problems too, i'm thinking enteropathy arthropathy. The ANA may be a red herring. Solving this type of problem is why we have primary care physicians; respectfully nobody here can address this beyond raising possibilities. Celiac sprue? Whipple's? Crohn's? Many possibilities. ...Read more
