Additional Information:

UFHPL Epic order code: LAB5851

CPT Code(s):

• 88239
• 88262
• 88291

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.

^{* 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
