  1. What is the meaning and impact of noninvasive fetal RhD blood group genotyping for pregnant people, and their health care providers?
  2. What are pregnant peoples’, and their health care providers’, expectations of noninvasive fetal RhD blood group genotyping, and the results of such tests?

Key Message

Pregnant people and health care providers find fetal RhD genotyping beneficial and feel it should be offered to all RhD negative pregnant persons.   While fetal RhD genotyping is considered beneficial, there is residual concern around the identification of false negatives leading some people to prefer to receive anti-D immunoglobulin despite their test result.   Pregnant people often experience information overload throughout pregnancy and appreciate when information on fetal RhD genotyping can be taken home in the form of informational pamphlets.
