Iron Studies
Every iron studies calculator on CalcEngines — unit converters, derived indices and interpretive tools, each with its formula, a worked example and the reference intervals it is judged against.
24 calculators in this section
- Elemental Iron in Oral Iron Salts ConverterConvert the tablet strength printed on an oral iron pack into the elemental iron it actually delivers.
- Erythropoietin (EPO) Unit ConverterConvert erythropoietin between mIU/mL, IU/L and mIU/L, with the adult reference interval and what a high or low value means.
- Ferric Carboxymaltose Dose CalculatorWork out the cumulative ferric carboxymaltose dose from body weight and haemoglobin using the simplified label table.
- Ferritin Correction for Inflammation CalculatorApply the right ferritin threshold for a patient with raised CRP, where the usual 30 µg/L cut-off no longer excludes iron deficiency.
- Ferritin Unit ConverterConvert serum ferritin between ng/mL, µg/L, µg/dL, nmol/L and pmol/L, and see instantly whether the value sits inside the reference interval.
- Functional vs Absolute Iron Deficiency InterpreterDistinguish empty iron stores from iron that is present but locked away, using ferritin, transferrin saturation and CRP.
- Haptoglobin Unit ConverterConvert haptoglobin between mg/dL, g/L and mg/L, with the adult reference interval and what a low value means in haemolysis.
- Hepcidin Unit ConverterConvert hepcidin-25 between ng/mL, µg/L, nmol/L and pmol/L, with a note on why reference ranges are not transferable between assays.
- High Ferritin Interpreter: Iron Overload or Something Else?Work out what a raised ferritin means. Transferrin saturation is the fork: raised with a raised ferritin points to iron overload and testing for HFE haemochromatosis; normal points to inflammation, alcohol, liver disease, metabolic syndrome or malignancy, which cause most high ferritins. Very high values raise HLH and Still's disease. Thresholds from the 2018 British Society for Haematology and 2022 EASL guidelines — including where they disagree.
- Iron (Fe) Unit ConverterConvert serum iron between µg/dL, µg/L, mg/L and µmol/L, with adult reference intervals for men and women.
- Iron Deficiency Staging InterpreterPlace a patient on the spectrum from depleted stores through iron-deficient erythropoiesis to frank iron deficiency anaemia.
- Iron Deficit (Ganzoni Formula) CalculatorCalculate the total iron deficit in milligrams from body weight and haemoglobin, the standard basis for intravenous iron dosing.
- Iron Studies Panel InterpreterEnter a full iron panel — ferritin, serum iron, TIBC and CRP — and get the pattern it represents in one reading.
- Iron Sucrose Dose and Schedule CalculatorConvert a total iron requirement into the number of iron sucrose infusions needed, at the standard 200 mg per session.
- Liver Iron Concentration (LIC) InterpreterGrade hepatic iron loading from an MRI R2* or biopsy liver iron concentration, and see the chelation threshold each band implies.
- Soluble Transferrin Receptor (sTfR) Unit ConverterConvert soluble transferrin receptor between mg/L, µg/mL and nmol/L, with the caveat that reference ranges are assay-specific.
- sTfR-Ferritin Index CalculatorSeparate iron deficiency from anaemia of inflammation using the ratio of soluble transferrin receptor to the log of ferritin.
- TIBC from Transferrin CalculatorEstimate total iron binding capacity from a measured transferrin concentration when your laboratory reports one but not the other.
- Total Iron Binding Capacity (TIBC) Unit ConverterConvert TIBC between µg/dL, µg/L and µmol/L, and see where the value sits against the adult reference interval.
- Transferrin from TIBC CalculatorEstimate transferrin concentration from a reported TIBC, for guidelines and drug labels written in terms of transferrin.
- Transferrin Saturation (TSAT) CalculatorCalculate transferrin saturation from serum iron and TIBC, and read it against the thresholds for iron deficiency and iron overload.
- Transferrin Unit ConverterConvert transferrin between mg/dL, g/L, mg/L and µmol/L, with adult reference intervals.
- UIBC from TIBC and Iron CalculatorDerive unsaturated iron binding capacity from TIBC and serum iron, or check that a reported set of iron studies is internally consistent.
- Unsaturated Iron Binding Capacity (UIBC) Unit ConverterConvert UIBC between µg/dL, µg/L and µmol/L, and see the value against the adult reference interval.
