Lupus

[Gisèle]

I am 18 year old female. About a month and a half ago, I had a blood test and everything was normal. Three weeks ago, I had a blood test and it showed low WBCs, low lymphocytes, and low neutrophils. This was before I had a new onset of symptoms(on and off flu feeling, joint pain, low-grade fever, bad headaches.) Now about a week ago, I got another blood test to test specifically for lupus and everything came back normal, but I still have all of my symptoms, including unknown causes of inflammation inside my body. Is it possible that I could still have lupus? My doctor doesn't know what else could fit my symptoms, and neither do I. Is that possible to have a negative test, but still have lupus could it possibly be positive in the future?
