What Could Cause A Positive ANA Test Without Any Typical Symptoms Of Lupus?
Question: My sister tested positive for Ana anti nuclear ...she does not have the typical symptoms of lupus .. she does get tired and some knee joint pain.. all her inflammatory markers were great c reative at 3.2 esr was low at 11 rheumatoid at less than 14.. all of her other blood work looks excellent except for a cholesterol level a little elevated.. could you get a false positive on this what other tests does she need to rule out auto immune diseases? She feels fine but has hormonal issues hot fllashes..the doctor did the test because she was not feeling well Mainly because of hormonal issues .. she is 60 years old. Thanks so much!
Brief Answer:
Yes it's possible
Detailed Answer:
Hello and Welcome to ‘Ask A Doctor’ service.
Yes, it's definitely possible to get a false positive result especially if the titres of the test are low if checked by immunofluorescence.
This test is not a screening test for autoimmune disorders,in fact it corroborate s our diagnosis in case it is strongly suspected in a particular patient.
Do i feel you can rest assured that she does not have any major illness.
If required you can check ANA by immunofluorescence if not already done.
Regards.

Did you state that you can rest assure that she does not have any serious disease? How do I find out her titers? The test only stated positive result. Are there several test for Ana..she said the doctor wanted her to take the test again and take some other reflex test? The fact that the other inflammatory test are good is that a good sign it may be a false positive? Does it indicate cancer? Would other inflammatory markers be up as well? Thanks so much!!!
