PCR test work-up
For single gene disorders, HLA matching and translocations, a unique PGD-PCR test must be established for you as a family.
The primary test for all cases uses linkage markers, small regions of DNA on human chromosomes, which can differ between the couple. Markers which are informative are put together to form a mini DNA fingerprint-the pattern of which tells us whether the embryo is normal or not.
PGD-PCR test workups take time to complete. No cycle can commence until the test is complete.
