Single-gene NIPT
Screening for a panel of serious single-gene conditions that arise new in a pregnancy and are missed by standard NIPT.
What it measures
Who it's for
Pregnant from 10 weeks where paternal age is over 40, an ultrasound has shown a skeletal or growth finding, or you want screening for the dominant single-gene conditions that chromosome NIPT cannot see. Adults aged 18 and over.
What you'll learn, and what you won't
Standard and genome-wide NIPT look at whole chromosomes and large segments. Single-gene NIPT reads specific genes in the placental DNA for new (de novo) or paternally inherited dominant changes, which together are about as common as Down syndrome but are not detected by any other prenatal screen. A high-chance result is confirmed by diagnostic testing.
A genetic test is one input to a doctor's assessment, not a diagnosis on its own. If anything needs prompt attention a doctor contacts you directly.
How it works
- Order online. Either use the request your own doctor has signed, or a KnowLuna women's health doctor reviews your details and requests the test.
- Collect the way that suits you: at a centre near you, with a home kit, or a nurse visit (options below). From 10 weeks of pregnancy. No fasting. Can be ordered with standard or genome-wide NIPT from the same draw.
- Results are ready about 10 to 14 business days from collection, explained in your account, with a doctor to talk them through and a genetic counsellor where a result calls for it.
Choose how you collect
Every option is the same accredited test and the same report. Pick what suits you at checkout; the fee, if any, is added to either pathway price.
A quick draw at an accredited pathology collection centre near you. Usually under ten minutes. Included.
A registered nurse comes to your home or workplace for a standard blood draw. Metro areas of capital cities; other locations on request.
Common questions
Who should consider it?
It is most often chosen where the father is over 40, where an ultrasound has shown a skeletal, heart or growth finding, or after a previous pregnancy affected by one of these conditions. It is also available simply because you want the broadest screening.
Does it replace standard NIPT?
No. It screens a different class of condition. Most women who choose it order it together with standard or genome-wide NIPT from the same blood draw.
Then decide.
