Gender Reveal with NIPT or Blood Test Results
Many parents now learn the baby's sex from a blood test rather than a scan. Non-invasive prenatal testing (NIPT) and similar early blood tests can often report the sex chromosomes, sometimes weeks before an anatomy scan. The catch for a gender reveal is that the result usually arrives in your inbox, app or phone call.
Ask for the sex to be kept separate
When you have the test, ask whether the sex can be left out of the main results, or reported separately. Some clinics and labs let you opt out of seeing it, or will tell a nominated person instead. Policies vary, so ask your provider.
Let someone else read it
A common approach is to give a trusted friend or relative your results login, or forward them the email unopened. They read the result and pass it on to your baker.
To keep it simple, they can use Gender Envelope: they open genderenvelope.com, tap Boy or Girl, seal it and set a PIN. You get a short link and PIN that you can send to the baker or party planner, and your friend doesn't have to make any phone calls.
Protecting the surprise
- Turn off email previews for a few days, or set a filter so results emails skip your inbox.
- Don't open the results portal yourself until your helper has read it; some show the sex on the first page.
- Mind the call: if results come by phone, tell the caller up front that you don't want to know the sex.
Good to know
Blood test results for sex are generally very accurate, but no test is perfect. If you have questions about your results, talk to your midwife, doctor or clinic.
Try it free: your doctor seals boy or girl on your phone, and you share a link and PIN.
