Results of lupus test positive. No family history so how is that possible?

In brief: Unknown cause

Many lupus patients do not have a strong family history of lupus.
It appears lupus patients have a genetic predisposition for the disease and then something activates the gene for lupus. A virus or bacteria or something else in the environment could set the lupus off. We do not know the exact cause.

lupus tests are not specific for lupus. See a rheumatologist to find out if the disease is present

In brief: False positive

Unlike a blood test which definitely identifies your blood type (for example, o positive, a negative, etc.
), the antinuclear antibody (ANA) is only helpful in making a diagnosis of lupus if a patient already has signs and symptoms of lupus. By itself, the ANA is often positive but no associated disease is identified.
