TechnicalRegister
The proportion of blood volume made up of red cells, expressed as a percentage or fraction.
A low haematocrit alongside the pale film prompted the analyser to reflex further iron studies.
Rarity runs from 0 (a word everyone knows) to 100 (almost never seen outside specialist or literary writing). Level is the word's real difficulty on the CEFR scale, from A1 to C2.
