“In comments to the press, Ms. Williams expressed disappointment at being unable to compete because of severe fatigue and pain, but gratitude for recently receiving a diagnosis of Sjögren’s syndrome that explained symptoms she had been feeling for some time,” said Ms. Dowd. “Unfortunately, her experience is not uncommon; proper diagnosis can take years.
Blood tests can be done to determine if a patient has high levels of antibodies that are indicative of the condition, such as anti-nuclear antibody (ANA) and rheumatoid factor (because SS frequently occurs secondary to rheumatoid arthritis), which are associated with autoimmune diseases. Typical Sjögren's syndrome ANA patterns are SSA/Ro and SSB/La, of which SSB/La is far more specific; SSA/Ro is associated with numerous other autoimmune conditions but are often present in Sjögren's.So these tests are "indicative".

Comments are most welcome! But please:
- No SPAM whatsoever, no supplements, no pharmaceuticals, no herbs or any other advertisements
- Absolutely no quack-doctors pushing their quack-BS websites (and if you are a quack, I will call you out)
- Be critical if you want to, but try to be coherent
Comments are moderated, because I am tired of Gerwyn-V99-The-Idiot and his moronic sockpuppets, and tired of the story of the two dogs, but I will try to publish everything else.
If you are not Gerwyn (and want to tell me something other than the story of the two dogs), then relax and write something! :-)
