Abstract:
Background:
Serum iron levels vary throughout the day, morning samples were
assumed to be higher than afternoon or evening levels. This
descriptive observational case study was conducted during June to
August 2013 in Khartoum state to determine the diurnal variation of
serum iron among healthy individuals.
Material and method:
A total of 70 apparently healthy individuals ranging in age
from17to35 years, were included in this study, 44.5% of them were
males and 55.5% of them were females. Serum iron level was
determined by FerroZine-iron complex spectrophotometry on blood
specimens obtained from volunteers at 8 A.M and 5PM automatically
by using COBAS INTEGRA system analyzer and categorized by age,
sexand sample time collection in all the study subjects.
Result:
The result showed there was diurnal variation of serum iron, and
there was significantly difference in morning (at 8am) and evening
(at 5pm) samples (P.value=0.00) related to age and gender.
Conclusion:
There was obvious difference between morning and evening
concentration of serum iron and there was a significant change in
results according to gender.
