Expected Turnaround Time
12 - 15 days
Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.
Formalin fixed paraffin embedded (FFPE) tissue; fixed cell pellets
One paraffin block or ten 10-micron thick section slides
Sufficient sample to obtain enough DNA to run microarray
Paraffin block transport pouch
FFPE specimen should be fixed in 10% neutral-buffered formalin or formaldehyde. Cell pellet should be fixed in 3:1 methanol:acetic acid.
Causes for Rejection
Improperly embedded preparation; decalcified bone or bone core
High resolution detection of genomic imbalances that may be present in neoplastic clonal evolution; provides detection of copy-neutral loss of heterozygosity (acquired uniparental disomy) associated with cancer gene mutation. The microarray will detect DNA copy-number changes at a threshold >1 Mb for deletions, >2 Mb for duplications.
This assay does not detect balanced rearrangements and low level mosaicism, or tetraploidy.
This test was developed, and its performance characteristics determined, by LabCorp. It has not been cleared or approved by the US Food and Drug Administration (FDA).
Whole genome SNP copy number microarray analysis using Molecular Inversion Probe (MIP) technology optimized for highly degraded FFPE samples or degraded fixed cell pellets.
