Hi mummies. Anyone had harmony test before and need to redraw? Why is that so? And if yes, do you repeat it?

I did harmony test..i did not have to repeat but gynae got mentioned to me before if need repeat is likely because not enough fetal DNA in maternal blood stream when blood was drawn.. sufficient fetal DNA is needed for this test to be accurate.. so thats y need retake the blood..

Hi dear. But i checked at 17 weeks. The gynae say should be alright by that week. But she said cant get a result. Ya might be sample error. I asked for a refund. Because no use to repeat and ended up pay for nothing.

I also want to know this.
