Harmony Test London 

Pregnant moms are required to go through various tests and scans throughout the pregnancy to monitor the health and wellness of the baby and the mother. Depending on your medical and genetic history, you should consider other types of tests to check for certain markers that might suggest health abnormalities in the baby. 

A harmony test is a commonly considered test among expectant mothers early in the pregnancy to clear any doubt about the child having any chromosomal conditions. 

What is a Harmony Test?

A harmony test is a non-invasive blood test that screens for certain chromosome conditions in pregnancy as early as 10 weeks gestation. 

During pregnancy, the baby’s blood contains tiny amounts of your baby’s DNA, called cell-free fetal DNA. The harmony NIPT test looks at this DNA to provide information about the likelihood of the baby having some of the most common chromosome conditions such as Down Syndrome, trisomy 18 and trisomy 13. 

The test involves a simple blood draw taken from the mother and analysed for foetal cell-free DNA (cfDNA). The result is a natural breakdown of the foetal cells found in the mother’s blood. 

Why Get a Harmony Test?

  • For the health of your baby and checking the likelihood of the most common chromosomal conditions 
  • For your peace of mind, having clearer answers to your questions and concerns 
  • The highly accurate test can identify more than 99% of Down Syndrome cases with a false-positive rate of less than 0.1%. 
  • You can take the test as early as 10 weeks of gestation up to 14 weeks, with results available in 5-10 business days. 
  • You can also obtain the sex of your baby with the harmony test. 

The harmony test is crucial to parents concerned about their baby having chromosomal abnormalities. The test can be used to screen for the most common chromosomal conditions like Down Syndrome, Edwards Syndrome, and Patau Syndrome. You can also check for Klinefelter Syndrome, Turner Syndrome, Jacob Syndrome, and Triple X Syndrome, and you can also determine the sex of the baby.  

How is a Harmony Test Done?

A harmony test is a multi-staged test that begins with one of our experienced sonographers performing an ultrasound prior to the blood test. The ultrasound confirms the baby’s health and ensures that you’re in the correct gestation period for the test. If you’re not over 10 weeks, we cannot proceed with the test because there is only enough cfDNA to perform the test after 10 weeks. 

After the scan, the sonographer will discuss the rest of the procedure with you. This will include a blood test. If you have any other questions throughout the test, we’re more than happy to hear them and respond to them. If you wish to proceed, we will take your blood sample and run the test. We will give you the estimated wait period for the test results.

Benefits of Getting a Private Harmony Test London

  • The Harmony test is more accurate in determining the likelihood of chromosomal abnormalities than standard testing. 
  • It has a higher detection rate, meaning if there is a chromosomal abnormality, the harmony test is more likely to pick it up than the standard test carried out at the 12-week gestation period. 
  • The harmony test has a lower false positive rate, meaning fewer women will be sent for invasive testing such as CVS or amniocentesis to confirm the results. 
  • It is a blood test that doesn’t pose any risk to the foetus 

The harmony test is not recommended for every expectant mother. However, it is a good option for women who do not want to risk the most invasive testing methods like CVS and amniocentesis. Taking a harmony test after high-risk results from the standard first-trimester screening may help to offer a clearer picture of the likelihood of chromosomal abnormality. 

Combined with a scan that can detect conditions outside the scope of the test, the Harmony test is extremely accurate and gives a more holistic overview of the risk of abnormalities to the foetus.
