Red cell phenotype calculator

Transfusion laboratories may find this and the Red cell compatibility calculator useful either when having to find blood for transfusion or communicating the availability of blood to clinicians as part of the clinical decision-making process.

1. Choose the desired red cell phenotype using the drop-down boxes below.
2. Click Calculate to determine how common the phenotype is in the general population.

For simplicity, figures are based on Caucasian frequencies, noting that for some phenotypes, variation does exist.

A further selection of phenotypes can be found by clicking the Other phenotypes button.
