The t,t-Muconic acid (URXMUCA) data were withdrawn from the Urinary Volatile Organic Compounds datasets (UVOC_G and UVOCS_G) in the NHANES 2011-2012 cycle, due to an observed issue with the internal standard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.

Updated Data
Data documentation and/or method documents have been updated for the files below, as indicated. No changes or corrections have been made to the data.
The insulin was performed 2005-2009 using the Mercodia ELISA assay and was switched in late 2009 to a Roche chemiluminescent immunoassay performed on the Elecsys 2010 analyzer. A crossover study was performed between the two methods. To trend 1999-2012 serum insulin, a “forward” fractional polynomial regression was added to the analytic note to derive 2011-2012 Roche-equivalent insulin values from the measured Mercodia insulin values from NHANES 2005-2008. See the analytic note on “change in methods for serum insulin.”
- Plasma Fasting Glucose and Insulin (Subsample)(GLU_G 2011-2012)
There was a change in late 2009 from the Mercodia to the Elecsys insulin method. For 2009-2010, a new Mercodia ELISA insulin method file was added in addition to the Elecsys 2010 insulin method file. See the lab methods Insulin-Mercodia ELISA and Insulin-Elecsys 2010 Immunoassay.
- Plasma Fasting Glucose and Insulin (Subsample) (GLU_F 2009-2010)
The insulin was performed 2003-2004 using the Tosoh immunoenzymometric assay and was switched in 2005-2006 to a Mercodia ELISA assay. A crossover study was performed between the two methods. To trend 2003-2006 serum insulin, a “forward” linear regression was added to the analytic note to derive Mercodia-equivalent insulin values for NHANES 2005-2006 from measured Tosoh insulin values measured in 2003-2004. See the analytic note on “Insulin regression equation to compare 2005-2006 data and 2003-2004 data.”
- Plasma Fasting Glucose & Insulin (Subsample) (GLU_D 2005-2006)
The insulin was performed 1999-2002 using the Pharmacia RIA assay and was switched in 2003-2004 to a Tosoh immunoenzymometric assay. A crossover study was performed between the two methods. To trend 1999-2004 serum insulin, a “backward” linear regression was added to the analytic note to derive Pharmacia-equivalent insulin values for NHANES 1999-2002 from measured Tosoh insulin values measured in 2003-2004. See the analytic note on “Comparison of NHANES 2003-2004 to NHANES 1999-2002 Insulin Values.”

Total Cholesterol and HDL-Cholesterol are being updated to include an additional laboratory method file for each dataset, due to a change in instrumentation during the 2013-2014 cycle. The Roche/Hitachi Modular P Chemistry Analyzer method file is being added to accompany the Cobas 6000 Chemistry Analyzer method file for both datasets. Two method files will now be made available under the “Laboratory Method Files” section for total cholesterol, HDL-cholesterol, and triglyceride in the Doc File of each dataset.
- Cholesterol – Total (TCHOL_H 2013-2014)
- HDL-Cholesterol (HDL_H 2013-2014)
