An Example of Paired Kidney Donation Possibilities

Sommer Gentry, PhD ’05, provided this example graph, which depicts 20 incompatible donor/recipient pairs (numbered 0 through 19). Each circle represents one donor/recipient pair, and each line connecting two circles indicates that a paired donation would be possible between the two connected pairs.

In this example, Pair 4 (donor blood type O, recipient blood type A) can match up with nine other pairs, because blood type O can donate to almost any recipient. Although Pair 13 (donor blood type B, recipient blood type A) has the same recipient blood type as Pair 4, it has far fewer opportunities for matching because its donor blood type (B) is less universal.
