Tests performed
Entire test performed in-house
Analytical Validity: Help
Accuracy: >94%, sensitivity: >94%, precision: 100%
Assay limitations: Help
This assay may not detect deletions and duplications if present in <20% of the tested sample. In some cases, breakpoints may be difficult to determine. This assay is unable to detect genomic rearrangements, point mutations in the gene(s) of interest, or copy number changes in genes with corresponding pseudogenes.
