Fetal Rhesus D test

Devyser US offers a proven, highly sensitive and accurate test* for non-invasive screening of fetal RhD in pregnant women to avoid unnecessary prophylactic treatment. 

RhD is a type of blood group that can cause immune reactions. People who lack RhD on their red blood cells are called RhD-negative. They can make antibodies against RhD if they are exposed to RhD-positive red blood cells.

*Laboratory Developed Test


Detect fetal RhD status from gestation week 10


Rh negative mothers carry an Rh negative fetus and would be unnecessarily exposed to a treatment with potential risks

State-of-the-art fetal Rhesus D test

Why test?

Fetal Rhesus D is a non-invasive test that can confirm the RhD status of a fetus in an RhD-negative pregnant woman. The test can help determine the fetal RhD type as early as the 10th week of pregnancy. As a result, RhD-negative women can avoid getting anti-D prophylaxis when it is not required, which is about 40% of the time. 

Improved safety

Predicts fetal RhD status with high accuracy and not only improves care for RhD-negative women but allows healthcare providers to apply a targeted approach to anti-D prophylaxis.
