A member asked:
Is a antinuclear antibody blood a sensitive test?
A doctor has provided 1 answer
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).
