Maternal sample (3 mL blood in lavender top EDTA tube or 2 cytobrushes or saliva)
AND

Fetal cells from amniocentesis or chorionic villi culture will be sent from the Cytogenetics Laboratory for all Molecular Genetics prenatal testing.

For Chorionic Villi Sample (CVS): if result is 46,XX (to confirm findings of normal female fetal karyotype)
For Amniotic Fluid sample: to rule out MCC (Maternal Cell Contamination)

Collection personnel MUST initial specimen container to confirm sample identity.

For a free cytobrush or saliva collection kit, please call 513-636-4474.

3 mL whole blood in lavender top (EDTA) OR 2 cytobrushes OR completed saliva kit (from Mother).

If a lesser volume of blood or saliva, or a smaller number of cytobrushes is sent, the laboratory will attempt to perform the test requested.  The laboratory cannot assure either a result and/or the ability to perform repeat testing and/or additional testing if the minimum volumes are not met.

Do not centrifuge (spin) tube

Store at room temperature  / Use overnight shipping (protect from temperature extremes, no ice)

HOURS of OPERATION: 6 AM - 12 AM (Monday through Friday, with more limited hours on the weekend)

This tests is performed for all prenatal Molecular Genetics tests and following a Chromosome Analysis : Chorionic Villi (CVS) or Chromosome Analysis : Amniotic Fluid (AF) testing.

If the CVS chromosome test result is 46,XX (or there is a question of maternal cell contamination - MCC - in the amniotic fluid chromosome test), we perfomr this test as a follow-up.
 

Polymerase chain reaction (PCR) amplification of 24, highly variable, short tandem repeats (STRs) followed by capillary electrophoresis for size discrimination to determine the various alleles at the 24 individual loci as well as chromosome X and Y specific products.
