Polyploidy is the condition in which a cell has more than two haploid sets of chromosomes: e.g. a triploid embryo has three sets of chromosomes and a tetraploid embryo has four sets. Polyploidy in a human embryo is not compatible with life. Polyploidy may not be identified most of the time with conventional PGT-A.
PacGenomics provides Polyploidy Test for a patient who has PGT-A along with embryo paternity test, upon request.
