Insights
This study provides national reference values for blood (hematologic) and iron analytes in the U.S. population. These estimates, based on NHANES III data, are crucial for clinical and research comparisons.
Area of Science:
- Public Health
- Clinical Chemistry
- Hematology
Background:
- The U.S. population's health and nutritional status is monitored through national surveys.
- Establishing reference ranges for hematologic and iron-related analytes is essential for accurate health assessments.
Purpose of the Study:
- To present national estimates of hematologic and iron-related analytes.
- To provide these estimates stratified by age, sex, and race/ethnicity.
- To establish reference values for the U.S. population aged 1 year and over.
Main Methods:
- Analysis of data from the third National Health and Nutrition Examination Survey (NHANES III), conducted from 1988-1994.
- Inclusion of laboratory test results from 26,372 participants in the civilian noninstitutionalized U.S. population.
- Calculation of statistical measures including mean, standard error of the mean, median, and percentiles.
Main Results:
- National estimates for hematologic and iron-related analytes are presented for the U.S. population (1988-1994).
- Laboratory values are provided with mean, standard error of the mean, median, and percentile distributions.
- Percentage distributions of these analytes are also included.
Conclusions:
- The presented data offer vital reference values for hematologic and iron analytes.
- These reference values are applicable for clinical diagnostics and longitudinal health studies.
- The findings support ongoing health monitoring and research in the U.S.
Objectives:
This report presents national estimates of hematologic and iron-related analytes for persons 1 year of age and over, by age, sex, and race/ethnicity.
Methods:
The analysis is based on data from the third National Health and Nutrition Examination Survey (NHANES III) (1988-94), which was designed to provide information on the health and nutritional status of the civilian noninstitutionalized U.S. population. The sample used for these analyses included the 26,372 participants who had laboratory tests.
Results:
This report provides mean, standard error of the mean, median, and percentile laboratory values for the U.S. population, 1988-94, for hematological and iron-related analytes. In addition, percentage distributions are provided.
Conclusions:
Data on hematological and iron analytes provide reference values for clinical and longitudinal comparisons.

Disorders of Erythrocytes
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.
