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 form (available at http://www.aruplab.com/genetics/forms.php).

Reference Interval:
By report
Interpretive Data: Counseling and informed consent are recommended for genetic testing. Consent forms are available online at www.aruplab.com.
Note: These studies involve culturing of living cells; therefore, turnaround times given represent average times which are subject to multiple variables. Results are generally available in an average of 12 days after receipt of a specimen.

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.
