I am sorry your daughter is dealing with illness. The speckled pattern is typically indicitve of Lupus, Mixed Connective Disease and Sjrogens. Now this does not mean she has any of these but I am sure the doctor will take the clinical history and symptoms into consideration along with the other positive test results too.
I assume your daughter is treating with a Pediatric Rheumatologist? Any idea what other blood test results showed up for positive or high? When is your daughters follow up appointment with the doctor?
Please keep us posted as you move forward and let us know how things progress. We have a few folks who come here for support as their kids have Lupus or some other auto immune process too.
I hope to get to know you better and good luck with your daughter.
A lot would depend on the titre of the result. Many people have a low positive ANA and typically this wouldnt be considered towards a Lupus diagnosis. The ANA can be positive in a range of other diseases. Do you know what her actual results were and what other symptoms is she presenting with? Is she seeing a Rheumatologist at this point?
If you give us a bit more information we may be able to help more
Take care and looking forward to hearing from you.
Welcome to the forum
I am sorry about your concerns for your daughter's health. A positive ANA especially at a higher titre is an important clue in diagnosis of lupus. But it is not specific to lupus and many other tests can provide additional important information. There can be abnormalities in the complete blood count, low white cells or anemia for example. Then there is a wide range of more specialised blood tests for auto antibodies such as anti ds- NA, or a protein called complement which is often lower than normal, tests for possible clotting problems such as lupus anticoagulant and anti cardiolipins, in fact all the usual tests that adults should get, including urine and kidney and liver functions.

There is a wealth of information available here so do not hesitate to ask for help. It is important that you know about lupus as you are your child's advocate and need to dialogue with the doctors on her behalf. There is an overwhelming amount of information so take it step by step. Ask for copies of all test results and learn to understand them and what they might mean - we can help you with that. This way you can little by little familiarise yourself with the terms. You can make sure all the right tests are being done and ask the doctors questions.
