Immunodiagnostics are used to assess patients
with suspected immunological conditions.
Clinical situations in which immune system components
are assessed include infection, where we use the
term seroconversion to describe a situation where
antibodies are produced against specific pathogens.
So the presence of an antibody against a particular bacterium
or virus will indicate that that person is seroconverted.
We measure immunological parameters in immunodeficiency that
can be quantitative measurements or qualitative measurements.
In allergy, sensitization
to allergens is measured.
In autoimmune disease, autoantibodies and
T-cell autoreactivity can be measured.
And finally in transplantation,
HLA matching takes place.
