  • WGA


Detects chromosomal imbalance that may be associated with fetal loss and is ideal for detection of complete or partial molar pregnancies.

The microarray will detect DNA copy-number changes at a threshold >1Mb for deletions, >2 Mb for duplications. Also will detect copy-neutral changes associated with uniparental disomy and identity by descent.


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.

Specimen Requirements


Preferred fixed products of conception (POC), formalin-fixed paraffin-embedded (FFPE) tissue


One paraffin block or ten 10-micron thick section slides

Minimum Volume

Sufficient sample to obtain enough DNA to run microarray


Paraffin block transport pouch


Specimen should be fixed in 10% neutral-buffered formalin or formaldehyde.

Storage Instructions

Room temperature

Causes for Rejection

Improperly embedded preparation
