| Specimen Required: |
Collect: Thaw media prior to tissue inoculation. Products of conception in a sterile, screw-top container (Wide mouth containers: ARUP supply #42710) 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 autopsy is performed: Chest wall cartilage (particularly if macerated), gonad, spleen, kidney, or other internal organs.
If no autopsy is performed: Placenta from fetal side is preferred (e.g. villi).
Also acceptable: Umbilical cord or achilles tendon.
Specimen Preparation: DO NOT FREEZE. Do not place in formalin. Transport products of conception in sterile, screw-top container filled with tissue transport medium. 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. Submit the Patient History for Prenatal Cytogenetics with the electronic packing list (available at http://www.aruplab.com/genetics/forms.php).
Unacceptable Conditions: Intact fetus. Frozen specimens. Specimens preserved in formalin.
Stability (collection to initiation of testing): Ambient: 48 hours; Refrigerated: Unacceptable; Frozen: Unacceptable
