Please collect umbilical cord blood specimen in a Sodium Heparin tube (dark green-top tube without gel separator). Do not use Lithium Heparin tube or other types of Heparin tubes.

• If you are an EXTERNAL healthcare provider with no access to Nationwide Children’s Epic system, submission of a completed  is required. For specimen type, please check the box for "Cord Blood" and check the test box for chromosome analysis.  
• If you are an INTERNAL ordering provider with access to Nationwide Children’s Epic system, no requisition form is required; please place the lab order electronically in Epic. 

For newborn patients, STAT blood chromosome analysis is available at extra charge (see Test Code: STATPB), which provides a verbal preliminary result in 2 business days and faster written report turn-around-time (typically available in 7 days). Please indicate "STAT" on the lab order if STAT analysis is desired.

If Microarray analysis is also desired, please submit additional cord blood sample (minimum 1 mL in EDTA). 

If evaluation of extra cells (beyond the routine 20 cells) is desired to evaluate for low-level mosaicism for chromosome abnormality, please request "Mosaicism Study" on the lab order and additional cells up to 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).

For prenatally obtained fetal cord blood sample, please order Percutaneous Umbilical Cord Blood (PUBS) Chromosome Analysis (test code: PUBS). 

This test evaluates chromosomes in 20 cells (cultured lymphocytes) from umbilical cord blood. This test is used to evaluate for numerial and structural chromosomal abnormalities such as aneuploidy, chromosome translocation, and chromosome inversion.

If additional FISH or mosaicism studies are recommended to assist in the result interpretation by the director, the clinician will be notified.
