Does everyone with a positive ANA test have lupus?
No. Approximately 10 million Americans have a positive ANA. There are about 1.5 million Americans with lupus. 95-98% of people with lupus have a positive ANA, the others do not. Most people with lupus have a positive ANA, but some do not. Many people have a positive ANA and have another autoimmune disease or no disease at all. The immunofluorescent pattern of the ANA is more significant than the titer number. Lupus usually presents with a speckled rather than homogeneous pattern. There are no definitive biomarkers for lupus.
If you are ANA positive and have high globulin level in the blood does that mean you have Lupus?
Not necessarily. ANA is a sensitive test for SLE (97% of people with SLE will have a +ANA test) but it is not specific, since ANA can be present in a number of other diseases as well as in some people with no disease. Therefore a + ANA test should be followed up by anti-dsDNA and anti-Smith which are markers specific to lupus.

People are more likely to have a positive ANA as they age. Many people with a positive ANA never show any signs of autoimmune disease at all. A speckled titer can be indicative of lupus. No one can predict or even give odds about your chance of defeloping lupus.

Why is lupus so frequently misdiagnosed?
== == Lupus symptoms tend to mimic many other diseases. Many times, the doctors look for many other things before looking for lupus. The phrase "But you don't look sick" is often associated with lupus. You tend to feel awful with this disease but look "normal." This can cause many patients who are misdiagnosed to feel like they are going crazy. Also, there is no single test to diagnose for lupus. A positive ANA in a blood test will sometimes show that one has lupus but it is not definitive.
Does a positive ana test mean the diagnosis is ra?
No. 98% of people with lupus have a positive ANA with a speckled pattern. People with rheumatoid arthritis will have a positive rheumatoid factor and possible a positive ANA but with a different pattern.
How do you know if you may have lupus if your ana was negative?
There is no definitive test for lupus. 3%-5% of people with lupus will have a negative ANA, especially if they are taking a medication like prednisone that suppresses the immune system. A diagnosis of lupus is based on history, symptoms, a variety of tests and process of elmination. Rheumatologists are the specialists who have the advance training to make this often tricky diagnosis. Google the American College of Rheumatology to find one.
