Please click on the Lab Form Link in the Forms Section to print and complete the Genetic Test Requisition Form. Submission of a completed Genetics Test Requisition Form is required.

This test is used to add-on chromosome analysis to the existing cell culture sample available in the laboratory. Cell culture from blood, amniotic fluid, products of conception, and tissue samples may be used. Result turn-around-time will vary for different tissue types and status of cell culture. Please note that cultured cells are typically discarded by the laboratory after a certain period of time; if cultured cells have been discarded, then new specimen submission will be required for chromosome analysis.

If STAT chromosome analysis add-on is desired, please call (614) 722-5321 and ask to speak to a laboratory genetic counselor to discuss feasibility.

If evaluation of extra cells (beyond the routine 20 cells) is desired to rule out low-level mosaicism, please request "Mosaicism Study" on the lab order and 50 cells will be evaluated at extra charge (CPT code: 88263).

If patient has a family history of known chromosome abnormality, please provide the family member's chromosome result information (attach a copy of test result if available). If the proband was tested at Nationwide Children's Hospital Cytogenetics Laboratory, please provide the proband name, date of birth, and accession number (if available).
