Specimen Requirements:
Solid Tumor Tissue: Aseptically obtain a sample (approximately 2 mm x 2 mm x 2 mm) and deposit it in RPMI or tissue culture medium.*
Do not freeze or fix samples in any manner contrary to the maintenance of cell viability. Maintain sample sterility; keep all specimens at room temperature; and deliver samples to the laboratory within 24 – 48 hours. Ship specimens at room temperature for overnight delivery.
- Frozen specimens
- Formalin, alcohol, or paraffin-preserved specimens
- Ambient: 24 – 48 hours old*
- Frozen: Unacceptable
* Cell viability of specimens requiring cell culture may be compromised in specimens greater than 48 hours old upon receipt. Refrigeration at 2° – 8° C may assist when a delay in delivery is unpreventable. Do not freeze or place specimens directly on ice.
Use:
This test is used to detect clonal cytogenetic changes in solid tumor tissue specimens which may provide classification and prognostic information.
Methodology:
Classic cytogenetic G-band analysis (karyotyping); requires cell culture
Reported:
10 – 28 days
Reference Values:
By report; interpretive
