Interpretive Data

Refer to report.

This test was developed and its performance characteristics determined by ARUP Laboratories. It has not been cleared or approved by the US Food and Drug Administration. This test was performed in a CLIA certified laboratory and is intended for clinical purposes.

Compliance Category

Laboratory Developed Test (LDT)


These studies involve culturing of living cells; therefore, turnaround times given represent average times, which 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) requireing 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).
