I got a positive lupus antibody test in june and was told i would need lifelong warfarin. is this accurate?

Not necessarily: If all you had was one positive lupus antibody test, then that is not an indication for treatment with warfarin. To make a diagnosis of antiphospholipid syndrome requires multiple positive tests over time in addition to a clinical finding such as a blood clot or miscarriages. http://www.rheumatology.org/practice/clinical/patients/diseases_and_conditions/antiphospholipidsyndrome.asp.

Need more informatio: There are a lot more details that we need. Hey positive antinuclear body by itself does not require lifelong warfarin. I suspect this advice was given because of other findings. Your rheumatologist should be able to help clarify this advice.
