I can usually schedule you an appointment the same week. What are you the gender police?Ĭall or email me directly to schedule. You sound really passionate about gender. It is a social construct which is made clear when we look at gender across cultures. It includes how we cut our hair, how much we speak in a group, and how we sit on the bus. This includes cultural expectations of how we dress, parent, walk, socialize, and talk. Gender encompasses most of the non-biological aspects of being male or female (or non-binary) within a given culture. This test tells you if your baby has a Y chromosome, and the sex of your baby (see above). Sex chromosomes are actually not always as simple as we learned in 4th grade!ĭoes this test tell me the gender of my baby? This is often due to a coding error someplace in the DNA which prevents hormones from being made or being functional within the body. Additionally, about 1 in 15,000 people who are born with XY chromosomes express female genitalia and sexual traits. This test is only looking for Y chromosomes, so if there were an additional sex chromosome or one was missing it wouldn't show in this test.

In those cases Sneak Peek offers a free retest.Īs with any chromosome there can sometimes be an abnormality of the sex chromosomes. Which is pretty darn close to 100%! As mentioned above, occasionally there may not be enough fetal DNA in a sample for an accurate test. The results are emailed directly to you (or whomever you appoint to get the email) in about 1-2 days depending on shipping times.īecause this test is only looking for Y chromosomes it is 99.9% accurate. Because there needs to be a specific level of fetal DNA in the maternal blood sample to get an accurate result, it is possible that if done very early the test may need to be redone. This is an early test which can be done as early as 7 or 8 weeks in most cases. Sneak Peek only looks at sex chromosomes if you are interested in other testing, ask your care provider. This is the same technology that is used to screen for other chromosomal abnormalities of the fetus (such as trisomy 21 also known as Downs Syndrome). If Y is found the it is nearly certain that the fetus has XY chromosomes. This test searches the maternal blood for Y chromosomes. You may remember from 4th grade science that human sex chromosomes are X and Y.
Sneak Peak uses Cell-Free DNA technology which finds fetal DNA in maternal blood.
