Summary

This study collects blood samples from pregnant women who are RhD-negative to help develop a non-invasive prenatal test. The test aims to determine the baby's RhD blood type from the mother's blood, potentially avoiding the need for more invasive procedures. Participants are RhD-negative women with a single, viable pregnancy between 12 and 28 weeks. The collected samples will be used for future research and test development.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this could lead to a simple blood test that tells an RhD-negative mother her baby's blood type without invasive procedures, reducing risks and anxiety during pregnancy.
What could go wrong
This is an early-stage sample collection study, not a test of a finished product. The future test may not prove accurate or may not be developed at all.
