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.
