Reference range basically originates in what is most prevalent in a reference group taken from the healthy population. It is a basis for a physician or other health professional to interpret a set of results for a particular patient. In our country it's preferable to redistribute a normal list of values instead of the old one, taking into consideration a specific reference ranges for population with any factor that may affects their measurement as, climate, type of food, and race. It should comprise both sexes; all age groups and between which 95% of values of a reference group fall into after enrollment of the inclusion/exclusion criteria.
To establish a reference ranges of some biochemical parameters for healthy adults' population.
one thousand healthy individual (aged 20-40 year), with 450 male and 550 female, selected from Baghdad city, from AL-Mammon University College and Ministry of Health, were recruited for the study between march.2011-april.2012 after they were subjected to an inclusion/exclusion criteria, reference ranges of some biochemical parameters was constructed by using the parametric methods to estimate 2.5 and 97.5 percentiles of distribution.
Specific ranges for some biochemical parameters shows somewhat a little bit difference in comparison to their counterparts from other countries. Moreover it was clearly noticed that the present dependent-format missed many important parameters as (HDL-Cholesterol), (LDL-Cholesterol) in addition to missing sex and age difference. Results also shows statistically significant higher values in female than male for (HDL-Cholesterol) (p=0.000), (Total Protein) (p=0.000), and lower values in females than male for (Uric Acid) (p=0.000), (CREAT) (p=0.000), (Blood Urea) (p=0.000).
There is a need for the national clinical chemistry laboratory to establish its own ranges for both sexes to all age groups, and to redistributes them in a new format.
