It can be used on losses that have recently occurred and on losses that took place several years ago.

Sometimes a part of one chromosome gets detached and attached to another chromosome. We have found this test to be invaluable. karyotype is another possible contributory factor, but there have been few analyses of the percentages of abnormal and normal karyotypes of aborted concepti with reference to the number of previous miscarriages.
