Analytical Validity: Help
This test is evaluated for analytical validity using an established validation process utilizing abnormal and normal specimens as per CAP, ACMG, and CLIA guidelines. Microarray platform includes oligonucleotide probes for the 898 genes known to be involved in carcinogenesis, subtelomeric, pericentromeric regions, as well as breakpoint “hot spot” intervals associated … View more
Assay limitations: Help
Although microarray detects microscopic and submicroscopic deletions and duplications undetectable by karyotyping, microarray will not detect balanced chromosome rearrangements, such as balanced translocations or inversions. It will not detect alterations in chromosome structure at areas of the genome not covered by the array. This technology will not detect sequence alterations … View more
