Actually, up to 40% of Sjogren's patients are sero-negative...staggering numbers.

You will find many different opinions on positive labs (and when they occur) with autoimmune diseases. Bottom line is that autoimmune diseases are still very poorly understood. There are MANY out there who flare or are in active states of disease, yet still sero-negative. Sometimes (I have read) medicines or other conditions might be the reason labs are negative. I have always been negative for Sjogren's yet, my disease was confirmed by lip biopsy and is in advanced stages.

I'm happy for you that you'll get some answers now and that makes treatment SOOO much easier and more effective.

When is your appt with the rheumatologist? Please keep us posted on the incoming labs.
