This test is New York DOH approved.
Specimen Required
Patient Preparation
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, sterile saline, or ringers.
If autopsy is performed: Facia lata, diaphragm, tendon, skin, tissue from internal organs (if fresh), chest wall cartilage (particularly if macerated) or placenta from fetal side.
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 (Min: 5 mg) 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 (fresh tissue or culture flask). Also acceptable: Refrigerated.

Unacceptable Conditions

Frozen specimens. Intact fetus. Specimens preserved in formalin. Specimens consisting of maternal tissue (decidua) only. Autolyzed or contaminated specimens.

Remarks

If specimen collection time is greater than 72 hours, testing may be compromised. The laboratory will make every attempt to culture the specimen. Send specimen to lab for testing.

Stability

Ambient: 48 hours; Refrigerated: 48 hours; Frozen: Unacceptable

Reference Interval
Interpretive Data

Refer to report.

Compliance Statement C: For human genetic inheritable conditions and mutations. This test was developed and its performance characteristics determined by ARUP Laboratories. The U. S. Food and Drug Administration has not approved or cleared this test; however, FDA clearance or approval is not currently required for clinical use. The results are not intended to be used as the sole means for clinical diagnosis or patient management decisions.

Counseling and informed consent are recommended for genetic testing. Consent forms are available online.

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.

This test must be ordered using Cytogenetic test request form #43098 or through your ARUP interface. Please submit the Patient History for Prenatal Cytogenetics form with the electronic packing list (https://ltd.aruplab.com/Tests/Pdf/65).
