Total Iron-Binding Capacity (TIBC)
Females, Age 40-49
The median total iron-binding capacity (TIBC) for US females aged 40-49 in the US population is 340.0 µg/dL (60.9 µmol/L), with 90% of the population falling between 253.0 and 440.0 µg/dL.

Data and Methodology
- Dataset
- NHANES 2017-March 2020 Pre-Pandemic ( NHANES 2017–2020 2020 , Survey-weighted percentiles from full MEC sample)
- Survey years
- 2017-2020
- Sample size
- 1,033 participants
- Reference population
- US civilian non-institutionalized females aged 40-49 from NHANES 2017-March 2020. Includes the full population (not restricted to healthy individuals) to reflect the population distribution.
- Exclusion criteria
-
- Missing total iron-binding capacity measurement (LBDTIB)
- Missing or zero MEC sample weight (WTMEC)
- Age outside 40-49 range
- Notes
- Percentiles computed using survey-weighted analysis (WTMEC weight, divided by 2 to pool two cycles). Total iron-binding capacity measured as LBDTIB in µg/dL.
