Test Overview

Test Methodology

Unstimulated short term cell culture and chromosome analysis. Fluorescence In Situ Hybridization (FISH) when indicated.

Test Usage

Identification of chromosomal abnormalities to assist in classification of malignant tumors. Most malignant neoplasms are associated with genetic changes and the observation of an abnormal cytogenetic clone is consistent with a neoplasm.

Reference Range

Interpretive report provided.

* Reference ranges may change over time. Please refer to the original patient report when evaluating results.

Specimen Requirements

Collection Offsite

Specimen transport should be arranged so that the specimen is received by MLabs the same day it is collected. Call for a STAT courier if necessary. Collect tumor specimen using aseptic technique. Place tissue in Chromosome Media, available from MLabs. Send at room temperature as soon as possible. Do not allow specimen to overheat or freeze. Small or necrotic samples and samples obtained without collection media are suboptimal.
