Important note: The testing laboratory will be closing for the Christmas period. Please send your samples by no later than the 12th of December as the laboratory will stop receiving and accepting samples on 16th December 2019. Should you have any queries or need more information, please contact us.
The highly advanced non-invasive test we offer relies on the analysis of fetal DNA in maternal blood to establish whether there are abnormalities in the number of chromosomes associated with certain conditions such as Down’s syndrome. Get the peace of mind you need with this simple NIPT test for only N/A. Results are ready in just 5 working days from the receipt of samples at the laboratory.
Why Choose a Non-invasive Test for Down’s syndrome?
- 100% safe for the expectant mother and baby
- Available at 10 weeks of pregnancy from your last menstrual cycle
- Chances of false positives lower when compared to other screening tests
- Can be carried out earlier in pregnancy than amniocentesis and chorionic villus sampling
Important: this test must be performed under the guidance of an OBGYN or related specialist.
Science behind the test
Once the blood sample is received, the laboratory will proceed to analyse chromosomes 13,18, 21, X, Y present in your fetus in order to establish whether there are chromosomal abnormalities. Using very advanced calculations, scientists will determine whether the fetus has too many or two few copies of this chromosome. Cells containing an abnormal number of chromosomes are known as aneuploidies and aneuploidies indicate the presence of conditions such as trisomy 21 (Down syndrome), trisomy 18 (Edwards syndrome), or trisomy 13 (Patau syndrome). All these conditions are characterized by an extra chromosome.
The non-invasive prenatal test for Down’s syndrome is not a diagnostic test (unlike, for example amniocentesis); however, it is a very sensitive screening test and has a detection rate of over 99% for Down’s syndrome with extremely low chances of false positive results.
The sample is collected by means of a medical blood draw. You will need to organize an appointment with somebody qualified to collect blood samples such as a nurse or phlebotomist. We will provide you with a sample collection kit which will contain all you require to collect the blood samples. You will need to undergo just a single blood draw.
Note: The client must find a doctor, gynaecologist or obstetrician who will advise them regarding the blood draw and collect the samples. We need to send the kit directly to the doctor, gynaecologist or obstetrician so ensure to provide us with the address.
Results for your NIPT Test
Your test report will include one of three possible results for chromosomes 21, 18, and 13: No Aneuploidy Detected, Aneuploidy Detected, or Aneuploidy Suspected (Borderline Value).
Can I carry out the test before 10 weeks?
No, you cannot carry out the test for Down’s syndrome earlier than 10 weeks. The reason for this is that the levels of fetal DNA in the maternal blood before 10 weeks will be too low to extract a significant amount of fetal DNA to provide an accurate result.
