Webin most cases, a positive ana test indicates that your immune system has launched a misdirected attack on your own tissue — in other words, an autoimmune reaction.

The higher the titer, the more autoantibodies are present in the sample.

You have a viral infection.

A positive result doesn't necessarily.

Weba positive test for ana may help determine the specific type of autoimmune disease that is affecting a patient.

Weba positive ana test (ana +) is virtually a sine qua non for the diagnosis of systemic lupus erythematosus (sle) since more than 95% of patients have a positive test, and the current classification criteria for sle require a positive ana test at a titer of ≥.

But some people have positive ana tests even when they're healthy.

The ana titer is a measure of the amount of ana in the blood;

A positive test doesn’t mean that you have an autoimmune condition.

You have sle (lupus).
