Specimen Required
Patient Preparation
Thaw media prior to tissue inoculation. Solid tumor 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.  
Specimen Preparation
DO NOT FREEZE. Do not place in formalin. Transport a 10 mm biopsy in a sterile, screw-top container filled with tissue culture transport medium. (Min: 5 mm) 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.  
Storage/Transport Temperature
Room temperature.  
Unacceptable Conditions
Frozen specimens. Specimens preserved in formalin.  
This test must be ordered using Oncology test request form #43099 or through your ARUP interface.

Interpretive Data
These studies involve culturing of living cells; therefore, turnaround times given represent average times which are subject to multiple variables. After specimen receipt, results are generally available in an average of 14 days.

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.
