I am going to have an ANA done Tuesday. I am on hydralazine 50mg daily. How long should I be off if it prior to the test so I don’t get a false positive?

@novakp52 Did your testing lab give you any direction? Or your rheumatologist? I wold ask them, as you may need to clear the hydralazine out of your system before the test. I read somewhere that it can skew the results up! I get it if you need to reschedule!

Are you being testing for Systemic Lupus, or drug induced lupus?
