=== Myriad Genetics Test ===

We skipped the carrier screens (OB had Natera pamphlets) because we had our genomes already done for the IVF process. Myriad tests the mother's blood for the foetal DNA and then concludes things based on that. The things they checked were:

* Trisomies: these affect 13, 18, 21 and the sex chromosomes X and Y
* Aneuploidy
* A bunch of other micro-deletions: e.g. 15q11.2 which causes developmental delays<ref>{{cite report

For the most part, we knew all of this from our Orchid PGT-WGS, and there were no surprises here. Absent other information, you can also learn the sex chromosomes here. These results took about a week to arrive.
