What do my ANA results mean?
An ANA test looks for antinuclear antibodies in your blood. If the test finds antinuclear antibodies in your blood, it may mean you have an autoimmune disorder. An autoimmune disorder causes your immune system to attack your own cells, tissues, and/or organs by mistake.
What do the ANA numbers mean?
In 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.
What is normal ANA range?
ANAs can be found in approximately 5% of the normal population, usually in low titers (low levels). These people usually have no disease. Titers of 1:80 or lower are less likely to be significant. (ANA titers of less than or equal to 1:40 are considered negative.)
What is the normal range for ANA titer?
Normal Results Low titers are in the range of 1:40 to 1:60. A positive ANA test is of much more importance if you also have antibodies against the double-stranded form of DNA. The presence of ANA does not confirm a diagnosis of systemic lupus erythematosus (SLE).
How to read the results of an ANA blood test?
How to Read ANA Blood Test Results. An antinuclear antibody (ANA) test is a blood test used to diagnose autoimmune disorders such as systemic lupus erythematosus (SLE). It may be ordered in conjunction with other autoantibody tests such as ESR (erythrocyte sedimentation rate) or CRP (C-reactive protein) for more specific diagnostic studies.
What are the symptoms of a high Ana reading?
Symptoms that precipitate the need for an ANA blood test include joint pain, fatigue and low-grade fever. The presence or lack of fluorescence indicates the results at different titers . Realize other diseases such as Addison’s disease, hepatitis, Hashimoto’s thyroiditis and some diseases of the blood cells can result in a high ANA reading.
Can a high Ana reading be a sign of lupus?
Realize other diseases such as Addison’s disease, hepatitis, Hashimoto’s thyroiditis and some diseases of the blood cells can result in a high ANA reading. While people with SLE usually have a positive ANA result, a positive ANA result does not specifically give a diagnosis of lupus (SLE).
What is the reference range for Ana?
The normal range of ANA blood test varies from laboratory to laboratory. However, a test result ranging between 1:40 – 1:60 is considered to be negative and is not a cause of concern.

Can you get a positive ANA with reflex test?
An “abnormal” test equates to a positive test result. About 95% of people who are eventually diagnosed with systemic lupus have a positive ANA with reflex blood test result. Other tests can confirm this diagnosis. Certain conditions may also cause a positive test result.
