Interpretive Data
Refer to report

These studies involve culturing of living cells; therefore, turnaround times given represent average times and are subject to multiple variables. After specimen receipt, results are generally available in an average 10 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.

If Chromosome Analysis is "normal" or "no growth," then Genomic Microarray testing will be added. Additional charges apply.
