Does a person have to have a positive result on all the blood test to receive a dx?

I have sysmptoms of lupus, a positive ANA titer, abnormal C3 and C4, Red blood cell count, Hemoglobin and Hematorcrit. All of these are low but not too low.

But my other SLE blood works are normal.

Is there a possiblity that I could still have SLE, since I have 5 on the citeria list?
