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

Specimen and completed test request form, including clinical indication, must be received within 48 hours of collection.

Testing on a neonate, 7 days old or younger, will automatically order a preliminary chromosome analysis (intended to identify whole chromosome aneuploidies and large structural rearrangements). This will be reported under the same accession number as the final chromosome report, and is generally available in 2-3 days, if sample quantity and metaphase quality permits. Final results will be available within 5-7 days.

This test must be ordered using Cytogenetic test request form #43097 or through your ARUP interface. Please submit the Patient History for Pediatric/Adult Cytogenetic (Chromosome) Studies form with the electronic packing list (https://ltd.aruplab.com/Tests/Pdf/20).
