Ferritin Level

Ferritin reflects how much iron the body has in reserve. Women lose iron through menstruation, so their upper reference bound sits lower than men’s.

What it means

Within the normal range.

Formula

Result = band(Ferritin (ng/mL), sex)

Inflammation can push ferritin up too, so read it alongside another inflammation marker (like CRP) for an accurate picture.

What to enter

Input	Default	Accepted range
Ferritin (ng/mL) (ng/mL)A protein that reflects stored iron; too low points to anemia, too high to inflammation or iron overload.	160	1 ~ 1,000
Sex (M1 / F0)Where the formula splits by sex — enter 1 for male, 0 for female.	1	0 ~ 1

Step by step

FormulaResult = band(Ferritin (ng/mL), sex)

With the default numbersResult = band(160, sex)

AnswerResult = 1

Frequently asked questions

QHow is Ferritin Level calculated?

Result = band(Ferritin (ng/mL), sex) — Ferritin reflects how much iron the body has in reserve. Women lose iron through menstruation, so their upper reference bound sits lower than men’s.

QCan you walk through an example?

With Ferritin (ng/mL) 160ng/mL, Sex (M1 / F0) 1, the answer is Result 1.

QWhat do I need to enter?

Enter Ferritin (ng/mL), Sex (M1 / F0). The result recalculates as you type, and an empty box counts as zero.

QHow much does the answer move if I change a number?

Changing only Sex (M1 / F0) moves the answer to Sex (M1 / F0) 0.5 → Result 2 and Sex (M1 / F0) 1 → Result 1. The table below lays out five steps.

QHow are the numbers rounded?

Money is shown to the nearest whole unit, percentages to one decimal place and everything else to two. What you see is rounded; the calculation itself carries the unrounded value forward.

QAnything to watch out for?

Inflammation can push ferritin up too, so read it alongside another inflammation marker (like CRP) for an accurate picture.
