Harmony test

[IndigoJam]

Not sure if this is the right area so feel free to move if not but just wondering if anyone has had false gender results or inaccurate results with a harmony test?

I had one previously which was 100% accurate and I'm TTC again and thinking I might go down this route again when/if it happens but just wanted others opinions and stories.

Thanks

Hi IndigoJam,

There's a lot about this in "antenatal tests".

The harmony/NIPT test is very accurate for the sex unless there is a sex chromosome issue. Assuming the child is healthy and does not have this specific problem, they will either detect a X chromosome (girl) or a Y chromosome for a boy.

Generally the test is very accurate for T21, Down Syndrome but not so much for T13 and T18 (Pataus and Edwards). There is a possibility of getting false positives what can obviously cause a lot of stress and worry, that's something to be aware of.

It is also not classed as a diagnostic test, it's more of a "peace of mind" kind of thing.
