DNA and RNA analysis
Check the genes, regions and types of genetic change included in the selected test. If gene fusions involving ALK, ROS1, RET or NTRK1/2/3 are relevant, confirm the assay’s fusion coverage and whether RNA analysis is included.
For clinicians & laboratories
Epicheck supports test selection, coordinates sample transfer and laboratory analysis, arranges report delivery and involves specialists in interpretation.
Discuss testing| Clinical purpose | Testing approach | Sample type |
|---|---|---|
| Multiple genetic targets relevant to treatment | Targeted DNA and/or RNA NGS panel | FFPE tumour tissue; plasma only for a validated plasma assay |
| A broader view of tumour genomic changes | Comprehensive genomic profiling (CGP) | FFPE tumour tissue |
| BRCA1/2 changes in the tumour | Tumour BRCA1/2 testing | FFPE tumour tissue |
| Inherited BRCA1/2 changes | Germline BRCA1/2 testing | Blood |
| A specific mutation, including a resistance-associated variant | Real-time PCR / digital PCR | FFPE tumour tissue |
Before ordering, confirm the genes and alterations examined, RNA-based fusion analysis and any validated TMB, MSI or HRD assessments. Plasma is used only for specifically validated tests.
Know what the test covers
Molecular tests differ in the genes and genetic changes they assess. Selecting a test means matching its coverage and sample requirements to the clinical question.
Check the genes, regions and types of genetic change included in the selected test. If gene fusions involving ALK, ROS1, RET or NTRK1/2/3 are relevant, confirm the assay’s fusion coverage and whether RNA analysis is included.
Tumour mutational burden (TMB), microsatellite instability (MSI) and homologous recombination deficiency (HRD) require specifically validated assessments. They are not included in every genomic panel. Confirm their availability and sample requirements before ordering.
Include the previous treatment regimen and timing and pattern of progression. A focused PCR test or broader NGS panel is selected according to the clinical question, previous molecular results and available sample.
Provide the diagnosis, disease stage, previous treatment and the question relevant to further management.
Tell us what sample is available and provide the histology report for tumour tissue. We supply preparation, submission and transport instructions for the selected test.
Confirm analytical coverage, informed-consent requirements, performing laboratory, cost, expected reporting time and the clinician receiving the report.
