Updated Data

Due to concerns of unexpectedly high Hepatitis D prevalence in certain NHANES cycles, Hepatitis D antibody testing was repeated with another assay for 2007-2008 through 2017-2018 using the original samples.

No retesting was done for participants from 2019-March 2020 because the assay in question was not used in that cycle. However, updates were still made to the combined dataset of the 2017-March 2020 cycle to include the retesting results from 2017-2018.
