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 ≥.
Weba positive test for ana may help determine the specific type of autoimmune disease that is affecting a patient.
A negative test for ana can assist health care providers by decreasing the likelihood that a patient’s symptoms are caused by an autoimmune.
Weba positive ana reading alone does not indicate an autoimmune disease.
The ana titer is a measure of the amount of ana in the blood;
The higher the titer, the more autoantibodies are present in the sample.
Webyour test is positive if it finds antinuclear antibodies in your blood.
A negative result means it found none.
A positive test doesn’t mean that you have an autoimmune condition.
Weba positive result on an ana test means that antinuclear antibodies were found in your blood.
You may get a positive result if:
You have sle (lupus).
You have a different type of autoimmune disease.
You have a viral infection.
A positive result doesn't necessarily.
Weban antinuclear antibody (ana) test shows signs of autoimmune disease.
Diseases that may cause a positive ana include scleroderma, rheumatoid arthritis, thyroid disease, and other conditions.
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.
But some people have positive ana tests even when they're healthy.
