A repeat test can be done 4-6 weeks later, if worried about a false negative. Lupus should not affect the result, but if a person is on strong immuno-suppressive therapy, his antibody production may be blocked, which may make test results unreliable. ...Read more

Can an ANA test or any blood test used to diagnose auto-immune diseases show all the types of lupus?

However, patients with lupus confined to the skin, i.e. Discoid le or scle (subacute cutaneous le)may not have a positive ana. A positive ANA by itself does not necessarily indicate sle and is seen in a number of medical conditions. The diagnosis of sle is made on the basis of historical, clinical and laboratory criteria. ...Read more
