Details
Amendment Two
As of February 2021, significant changes were made to the SKBIO table to account for Amendment 2. The original SKBIO CRF had questions that were non-specific about the type of Skin Biopsy, because only a formalin-fixed biopsy type was allowed. As of Amendment 2, formalin-fixed and fresh skin biopsies are both allowed, so new questions have been added that are type-specific.
Because the previous variables in the early version of this form are equivalent to the formalin-fixed variables of the amendment 2 version, there was a mapping done so that old variables can be harmonized with the new variables. See the table below for more description about how the old and new variables relate.
