By report
Interpretive Data: Refer to report.



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: 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 10 days with 7-10 additional days required for microarray.

A processing fee will be charged if the client cancels this procedure after the test has been set up

When the result of Chromosome Analysis is "normal," then Genomic Microarray testing will be added. Additional charges apply.
