What to know
- Data tables for Ethylene Oxide Hemoglobin Adducts (ETHOX) were temporarily withdrawn on April 5, 2022.
- The temporarily withdrawn tables are located in the "Analysis of whole blood, serum, and urine samples" section for NHANES cycles 1999-2018.
- The tables include ETHOX data for non-smokers and smokers from 2013-2016.
- Corrected tables will be added once updated NHANES data files become available.
Ethylene Oxide Hemoglobin Adduct Data Tables Temporarily Withdrawn
On April 5, 2022, data tables for Ethylene Oxide Hemoglobin Adducts (NHANES variable name: ETHOX) were temporarily withdrawn from the National Report on Human Exposure to Environmental Chemicals. A correctable calibrator bias was discovered in the ETHOX measurement impacting NHANES cycles 2013 – 14 and 2015 – 16. The location of tables temporarily withdrawn and their associated NHANES cycle(s) are:
Analysis of Whole Blood, Serum, and Urine Samples, NHANES 1999-2018
- Ethylene Oxide Hemoglobin Adduct in Non-smokers (2013 – 2016)
- Ethylene Oxide Hemoglobin Adduct in Smokers (2013 – 2016)
Corrected tables will be added when updated NHANES data files are available.
