When I saw a specialist in Sydney about the miscarriage issues he did a fair few blood tests (about 16 vials) but Im not entirely sure which ones he did apart from the main clotting disorders (anti-phos, anticardio, Factor IV etc). The Mthfr would definately be one of interest if it hasnt already been done, as Ds2 has autism and people often mistake him for having down syndrome (he has a very flat nasal bone and big brown eyes, I can definately see what they see esp with his autistic traits). No karyotyping as far as Im aware.

Better start writing a list of things to bring up with the FS. Id rather go through all this testing, even if Ive had some done already, before we TTC again than go through another miscarriage.
