Dear Francie,
while it is true that acid demineralisation techniques will reduce
demonstrable iron in sections as seen in Perls Stain and others, EDTA will
also do this too, but not to the same extent.
As a rule of thumb, if iron stores can be demonstated, they are probably in
adequate amounts, however a Negative Perls stain in the presence of adequate
controls can not be interpreted as indicating Iron stores are inadequate or
absent. The assessment for the Haematologist should preferably be made on
the smears and accompanied with Serum Fe, Ferritin, TIBC, Transferrin etc.
as dictated by their own protocol.
