Iron Deficiency Indicator
Flag iron deficiency when ferritin is below thirty nanograms per millilitre and transferrin saturation is below twenty percent.
Description
Flag iron deficiency when ferritin is below thirty nanograms per millilitre and transferrin saturation is below twenty percent.
Iron Deficiency Indicator is a focused biology tool that flag iron deficiency when ferritin is below thirty nanograms per millilitre and transferrin saturation is below twenty percent. It calculates locally from the values you enter and exposes the result without changing the source observations.1
When to use Iron Deficiency Indicator
Use Iron Deficiency Indicator when you need to flag iron deficiency when ferritin is below thirty nanograms per millilitre and transferrin saturation is below twenty percent. Enter Ferritin and Transferrin saturation using the definitions and units below so the result can be reproduced.
- Ferritin
- A finite measured or assumed value greater than or equal to 0, expressed in ng/mL.
- Transferrin saturation
- A finite measured or assumed value from 0 through 100, expressed in %.
How Iron Deficiency Indicator calculates the result
The published tool contract uses this rule: Flag iron deficiency when ferritin is below thirty nanograms per millilitre and transferrin saturation is below twenty percent.
- Iron deficient
- Whether iron deficient is true.
Limitations of Iron Deficiency Indicator
The category is produced by fixed software thresholds. Those cutoffs may differ from a laboratory, field protocol, population, jurisdiction, or current professional guideline. It is informational and cannot diagnose a condition, select treatment, or replace professional interpretation of the original measurements. Transferrin saturation must remain between 0 and 100.
Alternative or Complementary measurements
Retain the original Ferritin and Transferrin saturation values and their units alongside the result. Ferritin Per Iron Ratio is useful when you instead need to compute the ratio of ferritin in nanograms per millilitre to serum iron in micrograms per decilitre. MCV Cross Check provides another view by helping you cross check a reported MCV against the computed mean corpuscular volume hematocrit x 10 / RBC and flag agreement within two femtolitres.
