What is a normal dsDNA result?
Explanation: A normal result is < 10 IU/mL (negative). EQUIVOCAL results in 10 – 15 IU/mL. Positive result > 15 IU/mL The results obtained by this method should be used as an aid to the diagnosis and should not be construed as a diagnosis in itself.
Can low vitamin D lead to ANA positive?

Does everyone have anti-dsDNA?
