Laboratory assay overview
Chromosome analysis of products of conception (POC) can detect fetal chromosome abnormalities, which are associated with approximately one-half of all first trimester spontaneous abortions. Chromosome testing on fibroblasts obtained from a tissue biopsy is performed to investigate tissue specific mosaicism not present in blood lymphocytes. Fresh cells from tissue biopsies obtained postmortem may still be suitable for chromosome analysis when the patient's blood is not available or viable. If chromosome analysis is unsuccessful, please contact the laboratory genetic counselor at 1-866-GENEINFO (1-866-436-3463) to discuss the option of adding chromosomal microarray (CMA) testing.
