Description

This assay is intented to detect single gene mutations associated with hematologic disorders. Purified genomic DNA is enzymatically sheared and targeted sequences are isolated by hybrid capture probes and sequenced by using an Illumina NGS platform.

This assay will not detect variants if present in only a small proportion of cells in the sample. This assay is not intended for post-treatment disease monitoring nor comprehesive germline evaluation and is not validated to detect all classes of genomic alterations, such as large structural events including fusions and copy alterations.

If indicated, panel-based testing can be performed for myeloid-focused genes (HCAPMY) or lymphoid-focused genes (HCAPL), or both myeloid and lymphoid-panels can be ordered together (HCAPA).
