NHANES: Lab 21 Removed - Update Forthcoming
Posted October 13th, 2006 by Lisa Broniszewski in Data Archive Updates, NHANESTHE NCHS has removed all NHANES Lab 21 “Volatile Organic Compounds” data files. The files were removed because of errors in identifying the results that were below the limit of detection, and in the fill values used for results that were below the limit of detection. A corrected data set will be released in October 2006.
