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.

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 pregnant mother and then, detect the presence of all or part of a third copy of chromosome 21 as in Down syndrome.

Non-Invasive Prenatal Paternity DNA Testing

We are focused on developing non-invasive prenatal diagnostic tests based on fetal DNA present in maternal blood. As early as 5 weeks gestation, testing involves a blood sample from pregnant mother, swab sample from alleged father.

Single Gene Disorder Testing

Ravgen’s technology allows for non-invasive prenatal genetic testing for single gene disorders and chromosomal abnormalities, such as CF, SMA, and sickle cell anemia. Feel free to contact us about specific disorder testing.

Prenatal Down Syndrome Testing

Our testing utilizes Ravgen’s technology to increase the percentage of fetal DNA present in blood from the pregnant mother to detect the presence of all or part of a third copy of chromosome 21.

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.
