You’re having a baby? Congratulations! Is it a boy or a a girl? Whether you want to plan the nursery, pick a name, or start shopping for clothes, baby gender testing makes it possible.


Until recently, the fun of planning for your baby’s arrival had to wait until after an ultrasound could take a peek to see whether a boy or girl was in your future. Now, you can learn the gender much, much earlier. The Generation® Jack or Jill? Test is currently offered to families receiving clinical testing and as of March 2016 is offered as a stand-alone test. Please contact our office for pricing information.

How does gender determination work?

The presence of fetal genetic material in the mother’s blood has made it possible to offer a non-invasive prenatal diagnosis to determine the gender of the baby. Since it is non-invasive, there are no risks to the mother or the fetus. The non-invasive approach is seeking Y chromosome-specific DNA in the maternal blood sample.

Is the test expensive?

Compared to invasive techniques such as CVS or amniocentesis, non-invasive testing is cost-effective enough for parents who are curious to know gender prior to birth. More important, it’s infinitely safer than either of those gender testing methods

When can it be performed?

The gender confirmation test (Y-chromosome detection) can usually be done starting after 11 weeks of gestation.

How do I get my results?

After seven to ten days, you will be contacted with the results. PRESENCE of the  Y-chromosome confirms the presence of a male fetus. An ABSENCE of the Y-chromosome indicates a female fetus. In rare situations (prior to 11 weeks) there is insufficient fetal DNA in the blood which will trigger an inconclusive or non-reportable result.

How accurate are the results?

For properly collected blood samples after 11 weeks, there is a 99% test accuracy. With this baby gender test, you can start painting the nursery!
