Morphology
complement + fixation + test
The noun phrase is compositionally built — it denotes a 'test' that involves 'complement' and a 'fixation' procedure — so some basic idea (a medical/laboratory test involving complement proteins and a fixation step) is derivable from the parts. However, the terms are technical and the specific purpose and procedure (mixing serum with antigen and complement to detect antibodies) are specialized and not predictable for a B1 learner, so it is only partially transparent.
Etymology
Complement fixation test comes from what the test does: complement are blood proteins that help antibodies, and fixation means the complement gets attached or used up when an antibody meets part of a germ. So if the complement is 'fixed' in the mix, doctors know the blood 'has antibodies' to that germ.
