Frequently, when reporting laboratory or clinical data, authors do not indicate the substance per se; rather, a value is given that was obtained by measuring a substance or some function or constituent of it. For example, one does not report "blood" but rather "blood cell count", blood pressure", or "bleeding time".
differential white/red blood cell count
hemoglobin level
agglutination titer
prothrombin time
heart/pulse rate (beats/min)
sedimentation rate (per hour)
total serum cholesterol value (or level or concentration)
increase in antibody level
creatine level (or clearance)
serum phosphorous concentration
rise in billirubin level (or increase in billirubin)
