Non invasive prenatal testing or NIPT can provide valuable information about your baby’s health, especially if you have reason to believe there is a higher chance of chromosomal abnormalities. However, it can be confusing to see that there are different types of NIPT.

Why Your Choice of NIPT Matters

Most forms of non invasive prenatal testing can provide reliable results for Down’s, Edward’s and Patau’s syndromes. The tests are also performed in similar ways, with a simple blood test. However, there are some important differences in what the tests can detect, how long it takes, and how accurate the results are. It is essential to visit a reputable clinic to ensure that you are getting a high quality NIPT test. You should also spend some time discussing the tests that are available with your doctor so that you can pick the one that is appropriate for your needs. The doctor will be able to provide personalised advice on which type of NIPT is right for you, depending on the risks of different types of genetic problems.

Comparing NIPT Options

The three types of non invasive prenatal testing performed at The Birth Company are the Panorama, Harmony and SAFE tests.  
    • Panorama: this is the earliest possible test as it can be done from nine weeks, it also provides extra information about abnormalities such as microdeletions that the other tests won’t detect so it can be a good choice if your doctor suspects these. However, it will take longer to receive the results, which should be available in about 9-14 days.
    • Harmony: is less likely to produce a false positive than the equally speedy SAFE test, but has a lower detection rate for Edward’s and Patau’s syndrome than the other tests.
  • SAFE: provides results in 3-7 days but doesn’t allow for analysis of the sex chromosomes, therefore cannot detect issues such as Turner’s syndrome.
