Oestradiol (E2) is the most potent of the three forms of oestrogen. In women it is produced primarily by the ovaries and varies dramatically across the menstrual cycle. In men it is produced by aromatisation of testosterone in fat, brain, bone and other tissues. Australian pathology labs report E2 in pmol/L; older US-style ng/dL or pg/mL conversions are sometimes seen on imported reports.

Ferritin is the body's main iron-storage protein. The amount of ferritin circulating in blood reflects how much iron is held in tissue stores (mostly liver, spleen and bone marrow). Because ferritin is also an acute-phase reactant, levels can rise temporarily during infection or inflammation, which can mask underlying iron deficiency.
