The 2021 Implementation Guidelines and Recommendations has been updated. In Appendix A, the Parent XML Element was changed from Tumor to Patient for three data items: NCDB--SARSCoV2--Test , NCDB--SARSCoV2--Pos , and NCDB--SARSCoV2--Pos Date . The Appendix A table was updated to agree with the XML Data Exchange Standard.
