Rnp Antibody Positive
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
Went to dr with hand, shoulder, hip joint pain. Ana reflex screen Ana positive 1.0 and rnp antibody positive 4.3. All others neg. Very scared!
Lab numbers: These numbers don't show changes at joints and with most auto immune disorders, you may have periods of pain and increased lab numbers, usually related to stress in your life, and once treated medically or with stress reduction, pain/lab should improve. May want xray of one of involved joints just inflamed which can return to baseline. ...Read more
I'm having negative DNA ,Sm and Rnp antibodies, but positive sm/rnp antibody,and high ANA titre speckled,so what is the diagnosis ?
Lupus: These serologies are rather non specific. The speckled ANA is non specific. In Systemic Lupus Erythematosis (SLE) it is usually homogeneous in its staining. Anti-Sm and Anti RNP can be see in mixed connective-tissue diseases and overlaps with SLE, scleroderma and myositis. As often is the case a specific diagnosis cannot be made. You need to see a Rheumatologist. ...Read more
Sm/rnp antibody- ANA choice- positive, speckled/titer: 1:1280; sm & rnp (done alone) negative; sm/rnp antibody (together?) positive 3.0 guessing mctd?
Heads up: One of the things that's frustrating about these antibody tests looking for different connective tissue diseases is that they are difficult to do and are fraught with pitfalls. I suspect you've had at least one lab error to complicate your workup. Have you have a tube test for u1-rnp? Your clinical symptoms and signs actually tell more about your diagnosis ; best direction for treatment. ...Read more
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
I was just diagnosd with mctd...No symptoms just rnp antibody of 1.9 and anachoice screen-positive...What lies ahead for me?
Diagnosis?: Connective tissue diseases can only be diagnosed if a person has symptoms and physical signs of a disease. Mctd cannot be diagnosed by blood test alone as a percent of the normal population has a positive rnp without any disease. It is not like checking your blood type (a positive, o negative, etc.). Ask your doctor how the diagnosis of mctd was made. ...Read moreSee 1 more doctor answer
What could a negative ANA and positive RNP antibodies mean? I have a history of chronic rheumatological symptoms, but my dr is not convinced its MCTD.
Lab problem: The ANA screening test is fraught with pitfalls, and if you have a way-high titer of U1-RNP on the tube test and symptoms / signs of mixed connective tissue disease (which is a rough thing) but ANA is negative, perhaps there's a problem with the substrate. Your physician will want to call the lab's pathologist -- he / she would be interested in knowing. Best wishes. ...Read more

I was just diagnosd with mctd rnp antibody of 1.9 and anachoice screen-positive the only symptom is joint pain in my hand/wrist (i do have carpal tnl?
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 moreSee 1 more doctor answer

Probably nothing: That low titer is not impressive, usually the RNP. Ask the doctor who ordered it. Why was the test ordered in the first place? ...Read more
After sore throat, blood panel revealed infection and possible mono. Only other off number was rnp antibody of 5.8. Ana of 5. Could mono cause uprnp?
No.: Your serologies suggest mctd, or mixed connective tissue disease. This is much milder than systemic lupus erythematosis, and in 28 years, I have never had a dire situation with any patient with this DX alone. There is no relationship with mononucleosus. Most patients are treated with hydroxycholorquine or low dose prednisone. Aches and pains: aleve! don't worry about it! ...Read more
Specific to patient: The test by itself is not diagnostic.. It depends on your evaluation, examination, clinical factors are the most pertinent. The lab reports are guidelines but not diagnostic in themselves. ...Read more
I have been reading online and have read that when the rnp is the only antibody that is positive that this indicated mixed connective tissue disease?
Labs can confuse.: The labs are just a fraction of what needed to get you better. Your history and physical exam will determine your treatment. Looking for which labs will delay and confuse. You need to develop a few paragraphs of all your issues and sit down with your doctor to put the pieces together. Began a wellness program and add in magnesium and acupuncture. ...Read more
In my labs it shows a positive ANA and then the lab automatically checks for antibodies...The only one was a low positive rnp..What does that mean?
Not a great deal.: Positive anas can be "false" positive. On the other hand an rnp antibody is not false. This combination would indicate mixed connective tissue disease. That having been said, I have many patients with a low titer rnp positivity and no signs of disease. Mctd is rarely a disease with major serious issues as other dx. ...Read moreSee 1 more doctor answer
I recently tested positive for rnp antibodies. I have in the past tested positive for ana. My symptoms: rashes, weakness, pain. Your interpretatio?
DEPENDS: Could be mixed connective tissue disease which combines features of scleroderma, myositis, systemic lupus erythematosus, and rheumatoid arthritis (with some sources adding polymyositis, dermatomyositis, and inclusion body myositis). Additional testing for the muscle enzymes, rheumatoid factor, echocardiogram (pulmonary hypertension) and other extractable nuclear antigens may help differentiate. ...Read moreSee 1 more doctor answer
