    The test is performed using approximately 5-10 cells obtained from a biopsy of the trophic ectoderm (TE) of a blastocyst on thet fifth day afterfertilization.
    The whole genome of the cell-derived human DNA is amplified and the increase or decrease in chromosome number is examined based on diploid/euploid chromosomes, which have two copies each.
    Depending on the specimen, mosaic aneuploidymay be detectedMosaic aneuploidy is a condition in which cells without chromosomal aneuploidy and cells with chromosomal aneuploidy are mixed in the analyzed fetal tissues. Mosaic aneuploidy may disappear as the fetus develops, but there is a risk that it may cause infertility, repeated implantation failure, or the birth of a child with birth defects, mental retardation or developmental disabilities.
