I've never heard of UI OMS. You could try posting this on lupus UK since anti-dsDNA is a test for lupus and other autoimmune diseases. Also, might be helpful to post a photo of the result sheet (perhaps you are not reading the results correctly?)
Have you asked your doctor to explain your results?
Got an email from my doc and answer was Yes, they are the same thing, so >10 is positive for both UI OMS & IU/ml - So I had 25 so I am Lupus Positive, Plus a positive ANA. It explains a lot as I have had terrible symptoms in addition to my Hashimotos (highly positive TgAb) so have now moved over to the Lupus forum to get some help
Doc said:-
UI OMS is French for units internationalle Org. Mondial de la Sante (our WHO). titre > 10 Ui OMS : Positif )
Usually anti-DNA antibodies are reported in IU/ml (international units per ml)
So that means you've been diagnosed with lupus or are they doing further testing? Typically, you will now get a full rheumatological panel, physical exam as well as urinalysis to check kidney function.
Have you been prescribed any meds? Hydroxychloroquine is typical.
