SCL 70 results

Recommended Posts

Firstly let me say I've already gleaned a great deal of information from this forum but I wanted to run my particular situation past people here. 


I went to my general practitioner recently with dry mouth/ulcers and he ran a series of specific ANA tests. SCL 70 was 1.4 which is regarded as positive. He did not seem to run the other test you mention on the forum. The general ANA pattern test. Is this required also? I've also read that you can have false positives with SCL 70 which is why the general ANA positive/negative test is useful. 


I have an appointment with a rheumatologist tomorrow so hopefully I will have more information then. Is there anything in particular I should ask of him?

Are you on any medications?  A lot of these can give you dry mouth and ulcers?

Are your eyes or any other areas dry?

Hopefully your rheumatologist will be able to tell you more.

Some people have positive ANA results with few or no symptoms and others seem to have autoimmune disease where ANA results are negative.

Diagnosis tends to be a combination of the assessment of symptoms, physical examination and ANA results.

Hi Alan,


Welcome to these forums!


I'm sorry to hear that you're suffering with a dry mouth and ulcers and as these can possibly be symptomatic with autoimmune diseases, I suspect this is why your rheumatologist has given you ANA tests.


As Dimarzio has advised, it is possible to have positive antibodies and yet never go on to develop full blown scleroderma and vice versa. Although useful in trying to obtain a diagnosis, blood tests are by no means conclusive and should be used in conjunction with other Common Medical Tests for Scleroderma. I've also included a link to our medical page on Preparing for Doctor Appointments, which I hope you'll find helpful and informative.


We do recommend that our members, if possible, consult a listed sceroderma expert, as this complex disease does require specialist knowledge and expertise to deal with all it's little idiosyncrasies.


Kind regards,
