Sending samples:

  • Put the glass microscopy slide containing the fixed nuclei within a rigid slide mailer box. Wrap this in plastic bubblewrap paper, and then place it in the protective courrier container.
  • Prepare the following documents:-  Request form for Preimplantation Genetic Diagnosis (PGD).- Instructions for blastomere fixation in embryos prior to PGD for aneuploidy screening and chromosomal rearrangements.
  • Send via email the name of the courier service used, and the number/code of the package to
