In brief: Yes

Yes, the ANA is sensitive in the case of lupus erythematosus meaning that if you have lupus, the ANA will be positive over 99% of the time (few false negatives).
However, it is very non-specific meaning that if you have a positive ana, you may have lupus or some other disease or nothing at all (many false positives).
