The following erythrocyte indices based on the preoperative complete blood count results will be calculated for each patient one day prior to surgical treatment:
* Mentzer index: MCV / RBC
* Green and King index: MCV2 x RDW / (100 x HGB)
* RDW index: MCV x RDW / RBC
* Shine and Lal index: MCV2 x MCH / 100
* England and Fraser index: MCV - RBC - (5 x HGB) - 3.4
* Srivastava index: MCH / RBC
* Ricerca index: RDW / RBC
* Ehsani index: MCV - (10 x RBC)
* Sirdah index: MCV - RBC - (3 x HGB)
* Sehgal index: MCV2 / RBC
The Ganzoni equation for calculating total iron deficit will be calculated for each patient one day prior to surgical treatment, using the following formula:
total iron deficit \[mg\] = body weight \[kg\] x (target hemoglobin \[g/L\] - actual hemoglobin \[g/L\]) x 2.4 + iron depot \[mg\]

Anaemic patients without iron deficiency, defined as: normal serum iron concentration, TSAT, TIBC, UIBC, and decreased HGB, HCT and RBC
Presence of other type of anaemia than iron deficiency anaemia (e.g. alpha- or beta-thalassemia, sickle-cell anaemia, etc.)
History of red blood cell transfusion in the period of 120 days prior to hospital-admission
Stage III, IV, or V of chronic kidney disease (creatinine clearance \< 60 mL/min)
Significant intraoperative bleeding, which requires transfusion of red blood cell products, calculated using the Gross-formula:
allowable blood loss \[mL\] = (estimated blood volume \[mL\] x (initial HGB \[g/L\] - HGB level when transfusion is required \[g/L\])) / average of initial HGB and HGB level when transfusion is required \[g/L\] The cut-off value for HGB level when transfusion is required is set to 80 g/L.
