dsDNA (Anti Double stranded DNA)

The anti-dsDNA test normal range varies slightly between laboratories but generally falls within 0 to 25 international units per millilitre (IU/mL). A result within this range is usually considered negative or non-reactive.

Double-stranded DNA consists of two polynucleotide chains whose nitrogenous bases are connected by hydrogen bonds. Within this arrangement, each strand mirrors the other as a result of the anti-parallel orientation of the sugar-phosphate backbones, as well as the complementary nature of the A-T and C-G base pairing.
