Hi Irish
I agree many people have dry eyes. But the inflammadry kit which tests for mmp-9 protein, confirms if the patient has inflammatory dry eye..... Which is caused mostly in autoimmune conditions like sjogren, ra, lupus etc. So this test alone should raise the probability of sjogren.
Im actually wondering if anyone knows if 100 patients have inflammatory dry eye per this test, how many of these actually are sjogren patients....
