Laboratory Values

Usually, in reports of clinical or laboratory data, the substance per se is not reported; 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 hemoglobin but hemoglobin level. Some other correct forms are as follows:

  • Differential white blood cell count
  • Agglutination titer
  • Prothrombin time
  • Pulse rate
  • Erythrocyte sedimentation rate
  • Total serum cholesterol value or level or concentration
  • Increase in antibody level
  • Platelet count
  • 24-hour urine output or volume
  • antinuclear antibody titer
  • mean corpuscular volume
  • hemagglutination inhibition titer
  • high-density lipoprotein fraction 
  • urinary placental growth factor concentration
  • urinary protein excretion

In reports of findings from clinical examinations or laboratory values, data may not be enumerated without repeating value, level, etc.
