Note

These studies involve culturing of living cells; therefore, turnaround times given represent average times and are subject to multiple variables.

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.

Specimens enrolled in external studies (e.g. COG studies) requiring additional work-up and/or supplementary data collection and submission will have the following charges added based on type and extent of work performed: Cytogenetics Study Submission Basic (3006071) or Cytogenetics Study Submission Extensive (3006072).
