Yes because if you are on meds like plaqinal it will show a neg test because the drug is working
Hi @A MyLupusTeam Member I have had Lupus since 2008 and have yet to have a positive blood test for Lupus.
I was diagnosed with Lupus after a kidney biopsy.
Apparently one of the tests takes years to become positive. I got excluded from a medical lupus trial; but the Dr. said I have Lupis. All the other tests confirm.
