Patients: 536

Highlights:

  • First clinical validation of Snowflake algorithm in two clinical cohorts
  • 305 kidney transplant monitored for donor-specific HLA antibodies (DSA)
  • 231 pregnant women monitored for child-specific HLA antibodies (CSA)
  • Comparison of Eplet matching (AbV and non-AbV), PIRCHE and Snowflake
  • In DSA/CSA-positive cases, Snowflake scores were elevated
  • Snowflake scores correlate stronger with Eplet scores than with PIRCHE
