• Physical Functioning (PFQ_H 2013-2014)

The t,t-Muconic acid (URXMUCA) data were withdrawn from the Urinary Volatile Organic Compounds datasets (UVOC_G and UVOCS_G) in the NHANES 2011-2012 cycle, due to an observed issue with the internal standard transition used for quantitation. It was determined that the internal standard quantitation scheme used was not consistent during the 2011-2012 cycle, and the data could not be recalculated, even after the issue was identified and corrected. A detailed analytical note has been included in the dataset. The documentation file and laboratory procedure manual have been updated to reflect the withdrawal of all URXMUCA data.
