MDCalc

RBC Units to Screen for Compatibility

Estimates number of donor RBC units to screen to obtain a desired number of antigen-negative units.

This calculator includes inputs based on race, which may or may not provide better estimates, so we have decided to make race optional. Learn more about our approach to addressing race and bias on MDCalc.

  • The default values provided are for a White donor population. They can be replaced with antigen frequencies in non-White donor populations (or antigen frequencies for antigens not explicitly listed).

Race

Race may/may not provide better estimates; optional
If no race is selected, results will be calculated using antigen frequencies for the White population.

Antigen profile: should the screen exclude RBC units with this antigen?
