How does the Birch Early Gender Test™ work? 

At JunoDx™, we’re working towards making reproductive genetic testing available to all expecting parents. Our goal is to use our clinical expertise and science-backed research to make high-quality reproductive genetic testing accessible for everyone.

Enter: The Birch™ Fetal Gender Test.

What’s the Birch™ Fetal Gender Test?

The Birch Early Gender Test is a safe, affordable, and reliable way to learn the sex of your baby from the comfort of your own home. With a simple prick of the finger and a bit of blood, we can examine placental DNA to determine whether you’re expecting a boy or a girl. 

And the best part? You can take the test as early as 7 weeks into your pregnancy!

With our Birch Fetal Gender Test, finding out the sex of your baby is simple:

Step 1: Order your kit. 

We’ll send you a package with everything you’ll need for the test — instructions, tools for collecting your blood sample, and packaging to mail it back to the JunoDx lab.

Step 2: Take the test.

Simply prick your finger and collect a few drops of blood in the tube. If you need help at any point, feel free to reach out to our team

Step 3: Send in your sample.

Use the prepaid shipping label to send your sample back to our lab.

Step 4: Get your results!

Within a couple of days, we’ll email you with the exciting news!

You can ensure high-quality results by paying close attention to our step-by-step instructions when collecting your sample.

Is the Birch™ Fetal Gender Test the same as a test I’d receive at my doctor’s office? 

Not exactly. Our at-home test looks for the presence (or absence) of Y chromosome pieces within the maternal blood. Since most women have two X chromosomes and most men have one X chromosome and one Y chromosome, if we find Y chromosome material in your sample, we'll know you’re expecting a boy. 

Some doctors’ offices use a blood test called non-invasive prenatal testing (NIPT) or non-invasive prenatal screening (NIPS) to examine a pregnancy for chromosomal variations and predict fetal sex. Our fetal sex test is designed to detect Y chromosome material in your blood for the purpose of predicting your baby’s sex, not screening for chromosomal variations.

The at-home Birch Fetal Gender Test is a great option for expecting parents who:

  • Don’t have easy access to NIPS through their healthcare provider
  • Aren’t necessarily interested in screening for chromosomal variations
  • Don’t want to wait until a mid-pregnancy ultrasound to find out their baby’s sex (and start planning their gender reveal!)

Is the Birch™ Fetal Gender Test Reliable?  

Yes, our early gender test has been proven to be very reliable. You can ensure high-quality results by paying close attention to our step-by-step instructions when collecting your sample.

There are a couple of things you should keep in mind when taking our test. 

  • Male DNA can contaminate your sample. If a male partner, friend, or family member touches your test kit, or if you don’t thoroughly wash your hands before testing, remnant DNA from a male’s Y chromosome could lead to falsely describing a female fetus as a male. Following our step-by-step instructions to collect your sample is critical to reduce the risks of cross-contamination with male DNA, and ensure high-quality results.
  • Other factors, such as a high body mass index (BMI), may result in a lower overall proportion of placental DNA in your blood, making it harder to get accurate results.
