Methods

SNP MICROARRAY-PEDIATRIC (REVEAL): Whole genome SNP-based copy number microarray analysis targeting 2.695 million copy number and allele-specific genome sites

Clinical Utilities

Pertinent medical findings must accompany the test request form. Call 800-345-4363 to request forms, or photocopy the Clinical Questionnaire for SNP Microarray. This test may also be performed on adults.

When a child tested with this assay is found to have an abnormal array of unknown clinical significance that may be clarified through parental testing, there will be no charge associated with the follow-up parental testing that is based on the child's results. All other parental follow-up testing will be charged, including (but not limited to) autism susceptibility regions, known microdeletions/microduplications, autosomal recessive deletions/duplications, and large copy-number changes with likely pathogenic significance. The child's abnormal array results will indicate whether parental testing will be performed at no charge and will include the appropriate parental follow-up test number. For parental follow-up testing for arrays not performed at LabCorp, call 800-345-4363 to speak to a genetic counselor.
