    Next Generation POC Genomic Testing

    About Next Generation POC Genomic Testing

    Service Overview

    The POC (product of conception) chromosome test is a test to determine the number of chromosomes in a miscarried fetus to determine if the cause of the miscarriage is a fetal chromosome abnormality or not. Next-generation POC genomic testing uses a next-generation sequencer (NGS) to analyze the number of chromosomes in a miscarried fetus.
    The test requires fetal-derived tissues such as chorionic villi and umbilical cord contained in miscarried products.The test amplifies the whole genome of human DNA from fetal-derived tissue and examines the increase or decrease in chromosome number based on diploid/euploid chromosomes, which have two copies each. Chromosome aneuploidy is detected as monosomy when the number of a particular chromosome is one, and trisomy when the number of chromosomes is three.
    Depending on the specimen, mosaicism may be detected.Mosaicism is a condition in which cells without chromosomal aneuploidy and cells with chromosomal aneuploidy are mixed in the analyzed fetal tissue. Mosaicism may disappear as the fetus develops, but at times it may lead to an increased possibility of miscarriage.

    Features

    ・Includes multiplicity analysis as the standard.
    ・Genotyping analysis of POC and mothers is also available (at an additional cost). May be able to determine if the tissue is of fetal origin.
    ・POC culture is not necessary because the test is performed using NGS.
    ・Since the test uses DNA samples, even minute amounts can be analyzed and frozen for storage.
