Microarray-Products of Conception (POC) Reveal® FFPE, Data Transfer
Also known as: aCGH, CGH, CMA, Microarray, Microarray Oncology
Use
For products of conception samples, this test will detect chromosomal imbalance that could be associated with developmental delay/congenital anomalies. It provides detection of possible uniparental disomy of any chromosome, the percent and location of homozygosity, including the degree of identity by descent. For oncology samples, this test will detect chromosomal imbalances that may be present in neoplastic disorders and clonal evolution. It provides detection of copy-neutral loss of heterozygosity of any chromosome, and the percent and location of homozygosity, that may be associated with cancer gene mutation.
Special Instructions
Pertinent medical findings should accompany the test request form. Please direct questions to genetic customer service at 800-345-4363. There may be an additional charge for formalin positive tissue samples requiring embedding and pathology.
Limitations
This SNP assay does not detect balanced rearrangements, low-level mosaicism (<10%), marker chromosomes that only contain heterochromatin or tetraploidy. Genotypes in some formalin-fixed tissues are unable to be determined, allowing only genomic dosage to be determined.
