Chromosome Analysis, Autopsy, Products of Conception, or Stillbirth

Useful For Suggests clinical disorders or settings where the test may be helpful

Diagnosis of congenital chromosome abnormalities in products of conception, including aneuploidy (ie, trisomy or monosomy)

Reflex Tests Lists tests that may or may not be performed, at an additional charge, depending on the result and interpretation of the initial tests

Testing Algorithm Delineates situations when tests are added to the initial order. This includes reflex and additional tests.

This test includes a charge for cell culture of fresh specimens and professional interpretation of results. Analysis charges will be incurred for total work performed, and generally include 2 banded karyograms and the analysis of 20 metaphase cells. If no metaphase cells are available for analysis, no analysis charges will be incurred. If additional analysis work is required, additional charges may be incurred.


If the POC chromosome study fails to produce dividing cells, the test will be resulted and Mayo test POCRF / Products of Conception (POC) Aneuploidy Detection, FISH, Fresh Tissue will be automatically reflexed and performed.
