What is anti-dsDNA normal range?

<30.0 IU/mL Negative 30.0 – 75.0 IU/mL Borderline >75.0 IU/mL Positive Negative is considered normal.

What is considered a high titer of anti-dsDNA?

Titer levels for anti-dsDNA antibodies were reported as negative (≤4 IU/ml), indeterminate (5–9 IU/ml), or positive (≥10 IU/ml). Average intra-assay reproducibility rates for a high positive panel and a low positive panel were 2.2% and 3.1%, respectively.

What is considered a positive dsDNA?

A positive result for double-stranded DNA (dsDNA) IgG antibodies in the appropriate clinical context is suggestive of systemic lupus erythematosus (SLE).

What kind of blood test is anti dsDNA?

The anti-dsDNA (anti-double stranded DNA) antibody test is a blood test that looks for antibodies to double stranded DNA. The anti-dsDNA antibody test is a very specific test for Systemic Lupus Erythematosus (SLE) because Anti-dsDNA antibodies aren’t found in any other autoimmune disorders.

How many SLE patients have negative anti dsDNA test?

About 30-50% of people with SLE have a negative anti-dsDNA antibody test. Anti-dsDNA antibodies are a type of autoantibody: an antibody produced by the immune system that targets something that the body’s own tissues are made of.

Are there any anti dsDNA antibodies for systemic lupus?

How many autoimmune hepatitis patients have anti dsDNA antibodies?

Positivity for anti-dsDNA antibodies occurs in ~30% of patients with autoimmune hepatitis, and concomitant positivity of anti-dsDNA and anti-mitochondrial antibodies occurs in up to 60% of patients with an autoimmune hepatitis–primary biliary cholangitis overlap syndrome 7, 8.
