What is the significance of ISO15189 accreditation?
ISO15189 accreditation ensures that the laboratory meets international standards for quality and competence in medical testing.
How are genomic alterations detected in this workflow?
Genomic alterations are detected through next-generation sequencing of extracted nucleic acids from cancer tissue samples.
What types of samples can be used?
Formalin-fixed paraffin-embedded tissues from non-small cell lung cancer are primarily used in this protocol.
What is the role of hematoxylin and eosin staining?
Hematoxylin and eosin staining is used to evaluate the tumor cell content in the samples before nucleic acid extraction.
Can this protocol be used for other cancers?
Yes, the protocol can be adapted for use with other types of cancer samples.
