April 20, 2021 Update Notice
On April 20, 2021, Volume Two of the Updated Tables, March 2021 was reissued to correct an error in the urinary metals tables found in the “Metals and Metalloids” section. Creatinine corrected summary data for urinary metals reported in NHANES 2015-2016 were incorrect due to a data processing error. Corrected tables can be found in the link to Volume Two posted below.
August 2, 2021 Update Notice
On August 2, 2021, data tables for Urinary N-Acetyl-S-(3-hydroxypropyl-1-methyl)-L-cysteine (NHANES variable name: URXPMM) were removed from the Updated Tables, March 2021. A correctable systematic bias was discovered in the URXPMM measurement impacting NHANES cycles 2005-06, 2011-12, 2013-14, and 2015-16. The location of tables temporarily removed from the Updated Tables, March 2021 and associated NHANES cycle(s) are:
- Volume One: pp 653-654 (NHANES 2005-06)
- Volume Two: pp 487-488 (NHANES 2011-16)
- Volume Four: pp 393-396 (NHANES 2011-16)
Corrected tables will be added when updated NHANES data files are available.

January 2019 Release Notice
On November 1, 2019, the NHANES 2007-2008 pooled data results for Dioxin, polychlorinated biphenyl (PCB), and organochlorine pesticide metabolites found in Volume 2 were updated to address discrepancies found in some age group, ethnicity, and gender categories. The discrepancies were limited to these pooled data results and might have been due to the weight variable used at the time of the original calculations.
