Definitions/acronyms/miscellaneous Flashcards
Allocation MELD or PELD score
The highest exception or MELD or PELD score, including liver-intestine points, available to the candidate at the time of a match run for a liver or liver-intestine
Alternative allocation system
A type of variance that allows members who are permitted to join the variance to allocate organs differently than the OPTN policies.
Alternative local unit (ALU)
A type of variance that creates a distinct geographic area for organ procurement and distribution
Alternative point assignment system
A type of variance that allows members who are permitted to join the variance to assign points for organ allocation differently than required by the OPTN policies
Antigen mismatch
When an identified deceased or living donor antigen is not recognized as equivalent to the recipient’s own antigens. (In cases where a donor or candidate only has one antigen identified at a human leukocyte antigen locus (HLA locus) (A, B, or DR) the antigens are considered to be identical at that locus.)
Approved MELD or PELD exception
A MELD or PELD exception or exception extension that met standardized criteria in OPTN policy or was reviewed and approved by the NLRB
Assigned MELD or PELD exception
A MELD or PELD exception or exception extension where the NLRB failed to make a decision within 21 days of the request submission and the candidate was assigned the requested score.
Bridge donor
A kidney paired donation (KPD) donor who does not have a match identified during the same match run as the donor’s paired candidate and continues a chain in a future match run.
Calculated MELD or PELD score
The highest non-exception MELD or PELD score available to the candidate according to policy. EXCLUDES LIVER-INTESTINE POINTS.
Calculated panel reactive antibody (CPRA)
The percentage of deceased donors expected to have 1 or more of the unacceptable antigens indicated on the waiting list for the candidate. The CPRA is derived from HLA antigen/allele groups and halotype frequencies for different ethnic groups in proportion to their representation in the national deceased donor population.
Chain
A set of KPD matches that begins with a donation from a non directed living donor to that KPD donor’s matched candidate. This candidate’s paired living donor then donates to the KPD donor’s matched candidate. A chain continues until a living donor donates to an orphan candidate, a waiting list candidate, or is a bridge donor.
Covered VCAs

Covered VCAs of the head and neck
Face, Larynx , vascularized parathyroid gland, scalp, trachea, vascularized thyroid, and any other vascularized body parts from the head neck
