Cell Culture for Possible Additional Prenatal Studies
Test Code10225
CPT Codes
88235
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".
