Autosomal or sex chromosome mosaicism not detected in lymphocytes may be determined in fibroblasts obtained from a tissue biopsy. Cells from organ biopsies obtained postmortem may still be suitable for chromosome analysis when the patient's blood is of questionable viability. Fetal tissues or extra embryonic membranes are frequently used to diagnose fetal chromosome abnormalities that are associated with approximately one-half of all first trimester spontaneous abortions.
