Several indices have been applied in assessing nutrition Iron status.
They can be classified as Clinical and Laboratory indices.
Laboratory indices are the most common methods used to assess iron nutrition status.
Hemoglobin: Hemoglobin concentration varies considerably with
age. Even when hemoglobin is related to iron deficiency and the
definition of IDA is based on hemoglobin concentration, some authors
have stated that it is not an adequate indicator when it is applied
as the only measurement, specially in populations with low prevalence
(it will be discussed later).
