SERUM FERRITIN AND ITS BIOLOGICAL VARIATION IN HEALTHY ADULT MALES
Abstract
Iron Deficiency Anemia (IDA) is the most
common nutritional deficiency worldwide.
Serum Ferritin is the most specific biochemical
test for diagnosing Iron Deficiency
Anemia. Biological variation is an
important factor to be considered in assessing
Serum Ferritin levels. AIM To determine
Biological Variation of Serum Ferritin
in Healthy Adult males .METHOD The
study population consisted of 8 apparently
healthy adult male subjects in the age
group of 19-25 years. Venous blood was
collected from each subject on 3 random
non-consecutive days during a 3 week period.
Serum ferritin was determined by an
enzyme linked immunoassay method. RESULT
The mean serum ferritin level of the
study group was 25.75 gl. The biological
(intra individual) coefficient of variation for
serum ferritin varied from 15.50 to 38.37
with a mean variation of 26.22 . Thus, our
results indicate that biological variation
contributed most to the intraindividual
variation.
