Patient History for Prenatal Cytogenetics


Mnemonic: ARRAY FE

Methodology: Genomic Microarray
Performed: On request
Reported: Varies
Specimen Required: Collect: Amniotic fluid OR CVS in cytogenetics tissue media (ARUP Supply #32788). If cytogenetics tissue media is not available, collect in plain RPMI, Hanks solution, saline, or ringers.
AND green (sodium heparin) from mother and father.

Specimen Preparation: Do not freeze specimen or expose to extreme temperatures. Do not place in formalin.
Transport 35-45 mL amniotic fluid in sterile centrifuge tubes or sterile container (Min: 10 mL) OR 20-30 mg CVS in a sterile, screw-top container filled with tissue culture transport medium (Min: 5 mg).
AND transport 10 mL each from mother and father of whole blood. (Min: 5 mL each).
Specimen(s) and completed test request form(s), including clinical indication, must be received within 48 hours of collection.

Storage/Transport Temperature: Room temperature (all specimens).

Remarks: The maternal and paternal specimens are used to interpret abnormalities found on the fetal specimen as appropriate. The maternal specimen is also used to rule out MCC contamination.

Unacceptable Conditions: Bloody amniotic fluid. Frozen or fixed specimens.

Stability (collection to initiation of testing): Ambient: 48 hours; Refrigerated: Acceptable but not ideal; Frozen: Unacceptable
Reference Interval:
By report
Interpretive Data: This test must be ordered using Cytogenetic test request form 43099 or through your ARUP interface. Please submit the Cytogenetics and Chromosome Studies Information Form with the electronic packing list.



Counseling and informed consent are recommended for genetic testing. Consent forms are available online at www.aruplab.com.

Refer to Statement C under Testing Information at http://www.aruplab.com.
Note: For Array AND amniotic fluid chromosomes, also order Chromosome Analysis, Amniotic fluid (2002293).
For Array AND CVS chromosomes, also order Chromosome Analysis, Chorionic Villus (2002291).
When submitting maternal blood, order ARRAY MATC (2002369) accompanied by a test request form for the mother. This test is performed at no charge.
When submitting paternal blood, order ARRAY PATC (2002371) accompanied by a test request form for the father. This test is performed at no charge.

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. The fee will vary based on specimen type.

For questions regarding ordering please contact ARUP's genetic counselor at (800) 242-2787 ext. 3922.
CPT Code(s): 88235 Tissue culture amniotic fluid or CVS; 88386 x6 Array based evaluation of multiple molecular probes 251 through 500 probes; 83891 x2 isolation or extraction of highly purified nucleic acid - Additional CPT codes modifiers may be required for procedures performed to test for oncologic or inherited disorders.
