Nipt Testing – TBC

Other testing - TBC

3 Simple steps:

  1. We draw a little amount of your blood for testing at 10 weeks or later in your pregnancy.
  2. The Laboratory receives your blood sample for analysis.
  3. Within 5-7 business days of receiving the sample, we will receive your results.

What is the NIPT test?

DNA snippets from your unborn child are present in your blood while you are pregnant. A new test called the Prenatal Test analyzes this DNA in a sample of your blood to determine your risk of having Down syndrome (trisomy 21), Edwards syndrome (trisomy 18), and Patau syndrome (trisomy 13). Up to 15% of Down syndrome instances in pregnant women can be missed by standard screening tests for all women. For all pregnant women, regardless of age or risk, Harmony was created to provide a more accurate prenatal Down syndrome screening test. It is a brand-new blood test based on DNA that has undergone rigorous testing in both pregnant women over 35 and those under 35.

NIPT Accuracy

Conventional screening will detect approximately 70-80% of pregnancies with Down syndrome.

Accurary test will detect over 99.9%.

Contrary to standard screening, vision has a false positive rate of less than 0.1%, as opposed to 5%. This indicates that the Vision test not only detects more Down syndrome-carrying fetuses but also lowers the likelihood of needless amniocentesis.

Clarity early

A single blood sample from your arm is needed for the Prenatal Test, which can be performed as early as 10 weeks of pregnancy or later. Typically, results are ready in a week. Other frequently used Down syndrome tests are carried out later in pregnancy and necessitate many doctor visits.

Minimises need for follow-up tests

The number of high risk outcomes is reduced thanks to Vision’s higher precision and low false-positive rate compared to previous testing. As a result, fewer women will require additional testing that requires an invasive treatment like amniocentesis.

Fetal sex chromosomes

As early as 10 weeks into pregnancy, the Vision Prenatal Test can be used to assess the X and Y chromosomes. Turner and Klinefelter syndromes can be tested for (at an additional expense; this is only accessible for singleton pregnancies) if you have an extra or missing copy of the X or Y chromosome. Does a low risk finding imply that the child is free of Down syndrome?
The possibility of a “false negative” occurs with every screening test, but it is substantially smaller with the Vision test than with traditional Down screening. Does a high risk result imply that the baby’s chromosomes are abnormal if I have one?
Not necessary, I say. It denotes a higher risk, and you will be given the choice of having an amniocentesis to check the chromosomes in person. To assist you in making that choice, support and counseling will be provided.

What if I have twins?

The Non Invasive Prenatal Test and technology can be used in twin pregnancies as well, but it is not appropriate for disappearing twin cases.

Will I always get a result?

100 women out of 300 will need to have the test repeated. In almost two thirds of these samples, we get a result. In the event that we are unable to achieve a result, patients will not be charged.
