seropositive singular
seropositives plural

Morphology

seropositive = seropositive (semi-transparent) = sero + positive

The noun use comes from the adjective 'seropositive' by zero derivation, but the medical meaning is only partly inferable because 'sero-' is a specialized combining form.

Etymology

A seropositive is a person or animal whose blood test shows specific antibodies. The word comes from sero- meaning 'serum', the clear liquid part of blood, and positive meaning 'showing', so a seropositive person literally has blood that 'shows' the antibody.
