Non Invasive Prenatal Test for Down’s Syndrome
Testing: Expectant mother
Timeframe: Within 7-10 working days of receipt of DNA samples
The non-invasive prenatal test we offer has been scientifically shown to be the most sensitive and accurate non-invasive prenatal screening test available. The test is not currently offered.
Why Carry Out This Test?
• The test is non-invasive, meaning there are no painful or surgical processes required
• 100% risk free without any chance of complications or miscarriages
• The test can be performed as early as 8 weeks
• It requires just a simple 10ml blood draw
• Tests for trisomies 13, 18 and 21
Important: A doctor will need to collect the blood sample required for this test. The sample collection kit will be sent to your nominated address.
What is Down’s Syndrome?
A trisomy is a condition where an extra chromosome is present in a cell nucleus. Down’s syndrome and Edward syndrome are just two examples. Instances such as these, where cells contain a number of chromosomes which is not the normal number of chromosomes, are referred to as aneuploidies. Down’s syndrome is one of the more common trisomies, affecting around 1 in 700 babies. In an average human being there are normally 46 chromosomes in every cell. When a child has Down syndrome, their cells contain an extra copy of chromosome 21 which results in cells containing 47 chromosomes (3 copies of chromosome 21) instead of the 46 chromosome copies we find in normal cells.
Researchers believe that having extra copies of genes on chromosome 21 disrupts the course of normal development, causing the characteristic features of Down’s syndrome and the many risks and health complications that are associated with the condition. Keep in mind that other genetic factors can play a role in how each person reacts to this genetic disorder.
Important: this test must be performed under the guidance of an OBGYN or related specialist.
The test we offer is only a screening test. Although this is the most accurate screening test available, it is not a diagnostic test and cannot confirm with 100% accuracy whether the unborn baby has Down’s syndrome. It is also important to remember that if your test comes back positive you may need additional testing. Your doctor may suggest you undergo chorionic villus sampling or amniocentesis.
Typically, when you order your test, the kit will be sent directly to your gynaecologist or obstetrician. The test requires a blood sample and you will need to find someone qualified to collect the sample using the required material inside our kit.
The testing involves a laboratory examination of the following chromosomes: 13, 18 and 21, as well as the sex chromosomes. Results are ready in 5 working days from the receipt of samples at the laboratory. Results will clearly state:
• A No Aneuploidy Detected test result means that this test identified the expected number of copies of chromosomes reported.
• An Aneuploidy Detected test result means that this test identified too many or too few copies of one of the chromosomes as seen on the report. This can indicate either a trisomy or a sex chromosome aneuploidy.
• An Aneuploidy Suspected test result means that this test identified more copies than expected of the chromosomes reported. This means that your provider should follow up on this result to obtain more information.

This non-invasive prenatal test is an important screening test that can help indicate whether the child being born will suffer from Down’s Syndrome. It is important to remember this test is 99% accurate – it is more accurate than any screening test available. It is however, not a diagnostic test. Furthermore, no test can guarantee with 100% accuracy that the child will be born free of all chromosomal abnormalities. This is the reason we strongly suggest consulting your doctor before and after taking this test. They will be able to guide you with your results and suggest further testing if required.
