Normal Laboratory Values (Haematology Reference Values)

In the following tables, normal haematology reference values for commonly requested laboratory tests are listed in traditional units and in SI units. The tables are a guideline only. Values are method dependent and normal lab values may vary between laboratories.

The following table is adopted from the Sixth Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure, National Institutes of Health.

Classification of Blood Pressure *
Category Reference value
Systolic (mm Hg) Diastolic (mm Hg)
Optimal < 120 and < 80
Normal < 130 and < 85
High-normal 130-139 or 85-89

90-99
100-109
³ 110
* For adults age 18 and older who are not taking antihypertensive drugs and not acutely ill. When systolic and diastolic blood pressures fall into different categories, the higher category should be selected to classify the individual's blood pressure status. In addition to classifying stages of hypertension on the basis of average blood pressure levels, clinicians should specify presence or absence of target organ disease and additional risk factors.
1 Optimal blood pressure with respect to cardiovascular risk is below 120/88 m Hg. However, unusually low readings should be evaluated for clinical significance.
2 Based on the average of two or more readings taken at each of two or more visits after an initial screening.
