Cell Culture for Possible Additional Prenatal Studies
Test Summary
This test is intended to preserve amniocentesis or chorionic villus samples (CVS) until molecular or other studies are completed. For example, if both parents are identified as carriers for an autosomal recessive disorder, the cells would be available for genetic testing of the fetus.

Includes
This test is ordered in addition to Chromosome Analysis, Amniotic Fluid, if additional monolayer cultures are needed to perform other tests on the submitted amniotic fluid sample. Specific details of the additional testing and testing laboratory are required to route these cultures.
If cells from the submitted specimen do not attach or proliferate in culture, a Prenatal Specimen Culture - will be substituted for the ordered test.
If results are not possible, the test order may be canceled and replaced by a "Cytogenetics Communication".
