A positive ANA titer can be found in a variety of rheumatologic diseases, such as lupus or rheumatoid arthritis.
As for the speckled pattern, in addition to lupus, dermatomysitis, mixed connective tissue disorder, scleroderma or Sjogren's syndrome can all be the cause.
That being said, a substantial proportion of the general population without disease can also present with a positive ANA test.
The next step would be a referral to a rheumatologist, who can do more specific antibody testing to exclude the aforementioned diseases.
