Specimen Requirements and CPT Codes

The Division of Human Genetics and Diagnostic Laboratories at Cincinnati Children's helps you fit the pieces together.

The Molecular Genetics Laboratory at Cincinnati Children's Hospital Medical Center provides a current listing of test requirements and CPT codes.  All tests include PCR based sequence analysis of all coding exons and intron/exon boundaries of gene specified unless otherwise indicated. 

* For most genetic tests, blood samples are not acceptable from patients having undergone bone marrow or stem cell transplantation.  Please send cytobrushes on these patients. Please call 513-636-4474 for a free cytobrush collection kit.

In-house analysis has shown that amplification of DNA from leukodepleted red cell concentrate is possible.  Recent literature indicates that donor white cells persist in the recipient for up to two weeks. If patient's results are not consistent with phenotype, retesting >14  days post transfusion is an option.

Please call our toll-free billing hotline at 866-450-4198 for current pricing, billing inquiries, or for assistance with insurance preauthorization.
