Sjogren's Syndrome: anti-Fodrin antibodies

Hello, Commrades!

I came across this information by accident, and I want to share with the group.

There is a new "early Sjogren's Syndrome" antibody in town, and her name is Fodrin.

Currently, this antibody test is only available at RDL Reference Laboratory, which I believe was recently purchased by LabCorp, meaning, you can get your blood drawn at LabCorp and if the anti-Fodrin test is ordered, they will automatically ship to RDL.

Here's a link to the test information at LabCorp:

Here's a link to RDL Reference Labs:

I would caution one not to get terribly excited about this antibody test quite yet, because it's likely not yet "accepted" by rheumatologists in clinical practice.

In any case, this info is now documented on PR for future use, I hope!

Interesting, thanks for sharing!

I am planning on sending blood samples to test for early Sjogrens soon. I have only found labs in the US and I live in Norway. The blood sample is apparently good to go for 5 days so I assume this shouldnt be an issues either way. Will def add Anti Fodrin!

I have negative standard Sjogrens labs, negative lip biopsy so the early sjogrens testing is the last one I need to rule it out.

Have you had Sjogrens testing done?
