MYGENVAR THYROID NEOPLASM GENE PANEL, NEXT GENERATION SEQUENCING
|
||
Geisinger Epic Procedure Code: LAB4083
Geisinger Epic ID: 168380
|
||
SPECIMEN COLLECTION |
||
Specimen type: |
Formalin-fixed, paraffin-embedded tissue (FFPE) OR Fresh tissue (including bone marrow aspirate) | |
Preferred collection container: |
Glass Slides
|
|
Specimen required: |
PREFERRED: FFPE tissue: Six (6) unstained slides (USS), 10 µm thickness each, in slide folder (protected from light) Bone marrow: 3 mL lavender-top K2 EDTA tube (part of Bone Marrow Panel Collection – Bone Marrow Aspirate – Two [2] K2 EDTA Tube[s]) Fresh tissue: Place in liquid medium (e.g., RPMI) |
|
Special notes: |
FFPE tissue: For non-Geisinger sites, send six (6) USS/10 µm thickness, H&E slide, source of specimen and tumor assessment. Alternatively, send the FFPE block and additional information. Bone marrow: For non-Geisinger sites, collection tube is included in the bone marrow (BM) collection kit. NOTE: Isolated/extracted nucleic acids are acceptable only from CLIA-certified laboratories or a laboratory meeting equivalent requirements as determined by CAP and/or CMS. |
|
| SPECIMEN PROCESSING |
||
Specimen processing instructions: |
Mix well immediately. Do not centrifuge or separate plasma from cells. | |
Transport temperature: |
FFPE tissue: Room temperature (18-25°C) Bone marrow/fresh tissue:: Refrigerated (2-8°C) |
|
Specimen stability: |
FFPE Tissue: Room temperature (18-25°C), indefinitely Bone marrow/fresh tissue: Refrigerated (2-8°C), 3 days. Specimen must be extracted within 3 days. |
|
Rejection criteria: |
FFPE blocks containing no tumor (evaluated by pathologist). FFPE tissues that have been decalcified. Insufficient DNA and/or RNA. Wrong collection tube. Improper storage or transport temperature. Stability limits exceeded. Shared or comingled specimens. | |

Test includes: |
This custom testing gene panel uses targeted next-generation sequencing (NGS) to detect genomic alterations, including: tumor mutation burden (TMB), microsatellite instability (MSI), single base-pair mutations and small insertions/deletions in the coding regions or adjacent intron/exon boundaries, copy number variants (CNV), gene rearrangements (RNA fusion) and exon skipping.
