For example, you failed to validate the manufacturing process for your dehydrated, dual layer amniotic membrane patch, TheraMend, which cannot be fully verified, to ensure that your process does not cause contamination or cross-contamination and prevents the introduction, transmission or spread of communicable disease through the use of the HCT\u002FP.
