What should you know about ngs bio?

A biopsy removes a small sample of tissue for examination. If the sample is suitable, a laboratory may sequence genetic material from it to look for changes that help classify a tumour or inform treatment discussions. Blood or another sample may be used when the clinical question concerns inherited DNA or when tumour tissue is difficult to obtain.

Sequencing is different from immunohistochemistry. Immunohistochemistry uses stains and antibodies to show selected proteins in cells, while sequencing examines genetic material. MRI can show anatomy but does not replace tissue analysis when a diagnosis requires cells. Each result answers a different question.

Ask whether the sample came from the tumour, normal tissue, or blood, and whether the test examined a focused panel or broader set of genes. Ask what a detected change means for your diagnosis and whether it could be inherited. The report may support genomic tumour profiling, but it does not independently select chemotherapy or another treatment.

Keep the laboratory report with your pathology records. Ask whether a finding needs confirmation, whether a repeat sample is useful, and how it fits with your imaging and examination. A clinician or genetic counsellor can explain family implications when relevant.

Call the care team if the sample was inadequate, the report recommends follow-up, or you are unsure whether a result is inherited. Seek urgent care for severe pain, heavy bleeding after a procedure, fever with marked weakness, breathing difficulty, or sudden neurological symptoms.

What was the source of the sequenced material? Which findings are actionable for my care? Could this result affect relatives? Do I need another biopsy or confirmatory test? How does the result fit with my imaging and pathology?
