Hello miacats,

Test results can be very confusing. According to the Mayo Clinics website, typical values for dsDNA antibodies would be:

<30.0 IU/mL (negative)

30.0-75.0 IU/mL (borderline)

>75.0 IU/mL (positive)

However, it is important to appreciate that different testing facilities may use slightly different techniques and so these figures may not apply for everyone - you need to have your test interpreted by your specialist to understand the significance of your individual result.

For a more general overview of diagnostics, the LupusUK leaflet is helpful.
