Note

These studies involve culturing of living cells; therefore, turnaround times given represent average times, which are subject to multiple variables.

A processing fee will be charged if this procedure is canceled at the client's request after the test has been set up or if the specimen integrity is inadequate to allow culture growth.

Place skin biopsy in a sterile, screw-top container filled with tissue culture transport medium (ARUP Supply # 32788) Available online through eSupply using ARUP Connect™ or contact ARUP Client Services at (800) 522-2787. If cytogenetics tissue media is not available, collect in plain RPMI, Hanks solution, saline, or ringers.

If specimen size is too large for a normal collection tube, a larger sterile container can be used such as a sterile urine cup and can be flooded with several tubes of cytogenetic tissue media.

This test must be ordered using Cytogenetic test request form #43097 or through your ARUP interface. Submit the Patient History for Pediatric/Adult Cytogenetic (Chromosome) Studies form with the electronic packing list (https://ltd.aruplab.com/Tests/Pdf/20).
