Crithidia Antibodies

About this test

The Crithidia Antibody test is a very sensitive screen for anti-double stranded DNA antibodies. These antibodies are found in 50% of lupus cases. 

This blood test uses bacteria called Crithidia lucillae, which contain double-stranded DNA like humans, to look for these antibodies and to confirm their presence in the blood.

The test is used to confirm a diagnosis of lupus in difficult cases but does not have value in monitoring the effects of treatment.

Who is this test for?

Our Crithidia Antibodies test is for those who either have a family history of, or are experiencing symptoms of lupus and would like to aid a possible diagnosis.
