Does it matter what the titre of rnp antibodies are when it is the only single one identified in diagnosing mixed connective tisseue disease?

Does it matter what the titre of rnp antibodies are when it is the only single one identified in diagnosing  mixed connective tisseue disease?

No: The diagnosis of mctd must first be made if the history and physical examination are indicative of a possible connective tissue disease. If those elements are present and the disease seems to overlap between conditions such as lupus and polymyositis and others, it is reasonable to do laboratory testing. Only then, if the rnp is above the reference lab normal, it will confirm mctd. Rnp alone: no dx. ...Read more

Positive Labs: Positive labs are meaningless unless you have symptoms. At this point, your doctor is aware of the positive results and will likely follow your symptoms. The positive simply means you are at a greater chance of developing symptoms though not everybody does. ...Read more

Can there be false positive rnp antibody tests even with a high titre of an ana?

Can there be false positive rnp antibody tests even with a high titre of an ana?

FALSE POSITIVE RNP: It is possible we need to know what your symptoms and signs are, and why the tests have been ordered.The lab test apways have to be interpreted along with complete clinacal findings if you have signs and symptoms of lupus, high ana, and doctor ordered rnp to confirm the diagnosis and it comes out positive.That in all probabilities is positive and not false positive. ...Read more

If I have a high positive ANA (1:640) speckled, nucleolar and low positive SMA (1:40), what further tests do I need to do? (Negative SS-A, SS-B, Smith, RNP, SCL-70, Anti Jo Abs)

If I have a high positive ANA (1:640) speckled, nucleolar and low positive SMA (1:40), what further tests do I need to do?  (Negative SS-A, SS-B, Smith, RNP, SCL-70, Anti Jo Abs)

? anti dsDNA: You've probably already had these more basic tests: complete blood count, sedimentation rate, C-reactive protein, urinalysis & rheumatoid factor. It appears to me that the ANA results with slight positive anti-Smith may suggest lupus; you need an antibody to double-stranded DNA (anti dsDNA) which is very specific & somewhat sensitive for lupus.All this needs to be correlated by your doc/specialist ...Read more
