In XRF analysis, Fe is conventionally reported as Fe2O3 (or Fe2O3T, for total). Fe 2+ can be measured by titration, and may then be reported as FeO. This then allows one to calculate a "true" value for Fe 3+, or Fe2O3 (or Fe2O3V, for vrai (true in French)). Sometimes, Fe is reported as FeOT rather than Fe2O3T.
