Time Sensitive
  


Mnemonic: CHR ST

Methodology: Giemsa Band
Performed: Sun-Sat
Reported: 7-14 days
Specimen Required: Collect: 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.

Remarks: This test must be ordered using Cytogenetic test request form #43097 or through your ARUP interface.

Unacceptable Conditions: Frozen specimens. Specimens preserved in formalin.

Stability (collection to initiation of testing): Ambient: 48 hours; Refrigerated: 48 hours; Frozen: Unacceptable
Reference Interval:
By report
Note: 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.
CPT Code(s): 88239 Tissue culture; 88264 Analyze 20-25 cells; 88291 Interpretation and report - Additional CPT code modifiers may be required for procedures performed to test for oncologic or inherited disorders.
