Abstract

ABSTRACT:
BACKGROUND:
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.
OBJECTIVE:
To establish a reference ranges of some biochemical parameters for healthy adults' population.
METHODS:
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.
RESULTS:
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).
CONCLUSION:
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.
