Prenatal Testing
Ravgen was founded with the goal of developing fetal DNA sequencing methods for patients seeking a prenatal test which is both safe during pregnancy and highly accurate.
LEARN ABOUT TESTING
Prenatal Down Syndrome
The key to developing this technology lies in Ravgen’s ability to first, increase the percentage of fetal DNA present in blood from the pregnant mother and then, detect the presence of all or part of a third copy of chromosome 21 as in Down syndrome.

Single Gene Disorder
Ravgen’s ability to increase the percentage of fetal DNA present in blood from the pregnant mother allows noninvasive prenatal genetic testing for single gene disorders, such as cystic fibrosis and sickle cell anemia.

Technical Information

Ravgen’s core technology is based on its ability to increase the percentage of fetal DNA that is found in the mother’s blood.  Through its research with free floating fetal DNA, the company has developed and patented a variety of noninvasive prenatal tests that simply require a safe blood draw from the mother.
