A member asked:
Can flu shot cause a false positive on ana test? if not what can? im nervous im taking it to test if i have sle i have all sypmtoms and blood clots

See below: A viral infection is more apt to cause a false positive ANA if drawn to close to the infection as opposed to the vaccine. There are lots of false positives. The ANA is interpreted in context of other labs tests, your exam and your symptoms/history. If you have symptoms suggestive of lupus, you need to be tested as early intervention and treatment makes a big difference in the outcomes of lupus.
