HelpHeme Gene Panel by NGS
Clinical System Name
Miscellaneous Genetic Test
Description
This assay is a multiplexed gene sequencing panel designed to detect mutations associated with hematologic myeloid and lymphoid 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. If indicated, additional testing for FLT3-ITD and CEBPA mutations for new evaluation of acute myeloid leukemia should be separately ordered.
This assay is not intended for post-treatment disease monitoring nor comprehensive germline evaluation and is not validated to detect all classes of genomic alterations, such as large structural events including fusions and copy alterations.
Single gene testing can also be ordered as a MISC genetic test.
Sample Requirements
Blood: 6mL in Lavender Top (EDTA); Minimum 1mL EDTA
Bone Marrow: 1-2mL in Lavender Top (EDTA); Minimum 0.5mL EDTA
Tissue, Fluids or Sorted cells: Sterile container in RPMI
Formalin-fixed paraffin embedded tissue (FFPE/PET) block
Slides: 10 unstained; Minimum 5 curls/Slides
Accepted:
Green Tops (Heparin), while green tops are accepted for testing, there is documentation that heparin can interfere with some PCR assays.
Extracted DNA from CLIA certified laboratory.
Formalin-fixed paraffin embedded tissue (FFPE/PET)
Tissue from curls cut from FFPE/PET blocks or stained cover-slipped slides
Unacceptable:
Specimens received beyond stability limit.
Specimens with low volume or inadequate WBC
Decalcified or unacceptable fixatives
Processing Instructions
Reject due to:
Spin: N
Aliquot: N
Temp: RT or 2 - 4 C (see Storage Location instructions)
Storage Location: During business hours, call Send Outs for special handling. If received after hours or on weekends, place sample in the CPA 1 refrigerator's Send Outs rack.
