Q

Reference ranges for Anaemia

A

FBC <130 in men, <120 in women AND children 12-14

MCV <80 = Microcytosis (iron deficiency more likely)
MCV >100 = Macrocytic

Ferratin - correlates to total body iron stores. Low ferritin suggests low iron except in pregnant people (2nd&3rd trimester)

Serum ferritin <30 = iron deficiency
however it is an inflammatory marker so can be raised despite iron deficiency in acute or chronic inflammation.
