Morphology

blood + serum

The meaning of 'blood serum' is directly derivable from 'blood' (the bodily fluid) + 'serum' (the clear yellow liquid remaining after blood clots): it denotes the serum that comes from blood. This noun+noun composition (source + substance) is a transparent, cross-linguistically common pattern, so a B1 learner who knows the constituents would readily understand it.

Etymology

The term blood serum names the clear, yellowish part of blood that stays after it clots and the cells and solids are removed. That's why 'blood serum' means the clear liquid doctors use for tests.
