I haven't seen much mention of this test but thought it may be worth bringing up. Nicox recently announced that it has partnered with Immco Diagnostics to promote a proprietary laboratory, called the Sjöe test for early detection of Sjögren’s Syndrome. The Sjö test is was developed by Immco Diagnostics.
At present it is essentially being marketed to ophthalmologists. There are a few rheumies using it. I'm curious as to whether any here have had it?
It is NOT a definitive test so I don't want to raise hopes in those trying to get a diagnoses hopes up. There is not a lot different about this test.. The primary components of the test are still the traditional markers (antinuclear antibodies [ANA], Ro, La, and Rf [rheumatoid factor]). If they are not positive, you are still limited on recieving a diagnoses. Even if they are positive there are additional requiremnts to be met.
The Sjö test combines three proprietary biomarkers (salivary gland protein-1 [SP-1], carbonic anhydrase-6 [CA-6], and parotid secretory protein [PSP]) with the traditional test. The newer antibodies were found in 45% of patients meeting the criteria for Sjögren’s syndrome, but lacking antibodies for Ro and La. In patients diagnosed with xerostomia for less than 2 years, 76% had antibodies to SP-1 or CA-6, while only 31% had antibodies to Ro or La.1
It is being market as a screening test to ophthalmologists and optometrist, something to add to their routine exams. In short the data doesn't exist to make it a diagnostic test but as profit opportunity to eye docs, it has tremendous possibilities, as does what can come from routine screening
