• DONOR EXCLUSION CRITERIA:
• History of malignancy with the exception of non melanoma skin malignancy.
• History of autoimmune disease.
• Known medical diagnosis of Zika virus infection within the prior 6 months, including post mortem screening.
• Serological evidence of HIV, Hepatitis B (surface antigen positive), or Hepatitis C infection.
• Evidence of systemic infection.
• Kidney Donor Profile Index (KDPI) > 70%.
