Dina, who is blood type A?, wants to donate blood to her friend Sarah, who is blood type AB?. Do you recommend for Dina to donate blood to her friend? Explain why or why not
What will be an ideal response?
Sarah has type AB? blood, which means that her erythrocytes have the A and B antigens only, and her plasma has neither anti-A nor anti-B antibodies. Her erythrocytes also lack the Rh antigens. Dina can safely donate blood since her A antigens will not react with Sarah's blood and both women lack the Rh antigen.
