No, we aren’t talking about religion here!
A patient at my infusion center has been GAD negative all along, but has Stiff Person Syndrome basednin other tests , history, exam.
As you know, you can have SPS and not have GAD65 positive serum levels.
He now tests positive for GAD65. This is curious.
I know that the GAD numbers vary greatly from patient to patient and within a patient. But didn’t know one could convert from GAD negative Stiff Person Syndrome to GAD positive.
