Compliance Statement B: For laboratory developed tests not using a RUO kit, and for FDA approved, cleared or 510(k) exempt assays with alterations. 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.

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. 

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.
