Should I be concerned about the donor's blood type?

1 min. readlast update: 02.06.2024

Some patients feel that the blood type of the donor is very important when choosing a donor. By selecting a donor whose blood type matches the husband's/partner's blood type, patients may feel more secure about issues related to confidentiality. The donor's blood type may be medically important to consider if the mother is Rh-negative (Rh-).

These women may develop antibodies to a fetus that is Rh-positive. It is also important to remember that children do not always inherit the same exact blood type as their biological parents. For example, a couple with blood types A and B could have offspring with any of the four blood types: A, B, O, or AB. Click here to use our blood type predictor tool.

Please keep in mind that if you elect to use the blood type of a donor as one of your selection criteria, you will decrease the number of donor choices available to you. To filter donor search results to only view donors that best suit your needs, fill out the Blood Type or RH Factor fields in the Advance Search portion.
