Very
few studies exist in our country and especially in our region to obtain
reference values and the few existing studies are quite outdated. When the criter for choosing the
population is taken into consideration the number of relevant studies
decrease even further We planned this study to see the effects of social
and economic development on heamatological parameters. Another reason for
designing this study was establishing more reliable referance values, due
to the tecnichal development in the laboratory techniques. We chose 24
regions randomyl, among all suburbs and counties of Ankara, the capital of
Turkey. 12 of the regions were selected from suburbs and 12 were from the
inner city region. We obtained venous blood samples from each region, by
stratifiying the population according to ages and analyzed them in our
haematology laboratory’s Coulter Model Max M analyzer.
‘’Educational
status of the parents’’ and ‘’economical status of the family’’ were taken
as the main factors and their effects on each parameter were analyzed to
for reference populations There were no significant differences in
reference values between the richest and poorest groups. RBC,HGB,HCT and
MCV values were lower in the group of children with less educated parents
compared to the others.
The
effects of age and sex were also studied, and age groups were slimplfy clinical use of the findings. Comparison of our findings
with those found in the literature revealed that hemaglobin levels were
lower in 0 to 2 years old babies and adolescents older than 15 in our
study.
As
RDW and MPV are new parameters entering clinical use there were no other
values to compare with our findings in Turkish literature. We found mean
RDW values as 14,4 % and MPV as 8,9±1,2fl,
which were similar to foreign studies. We also found that mean WBC values
decreased as age increased.
In girls older than 14,
hemoglobin, hematocrit and MCV values were significantly lower compared to
boys of the same ages (p<0,05). RDW was found to be higher in girls
(p<0,05). No effect of sex was found on WBC (p>0,05).
