THE REASON FOR THE POSITIVE SERUM IS BECAUSE SHE HAS BEEN VACCINATED.
SAD I agree but why is that sad?
There is no difference technically, serology test are reported as "reactive"=positive and "non-reactive"=negative. Just the way it's done and reported in the lab.
That could come under immunology?

The purpose of serology is that it helps scientists study and diagnose antibodies and diseases. It can also be use as part of a forensics study in a crime. Serology is the study of serum, in the human body that would be blood serum and other bodily fluids.
Well serology is defined as the science that deals with the properties and reactions of serums (reddish protein-rich liquid that separates out when blood coagulates/clots) especially blood serum and an HIV test searches for antibodies that bring about the human immunodeficiency virus one that causes AIDS.
Serology (ser -> serum; ology -> study of) is the set of experiments and tests that can be done using serum. Serum is the non-cellular component of blood. That is, it's the liquid (with all its lipids and proteins) that is left over after all the red and white blood cells have been removed. Serology could involve the measurement of antibody titers (amounts) or cytokine concentrations.
The study of bodily fluids is Serology.
Serology nonreactive means negative for the presence of the analyte being detected in the test system.

Serology is the study of the liquid portion of the blood, and DNA testing is looking at what gene sequences you have.
