Test Overview
Unstimulated short term cell culture and chromosome analysis. Fluorescence In Situ Hybridization (FISH) when indicated.
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.
Interpretive report provided.
Cells must be capable of dividing. Small samples or specimens older than 24 hours may not grow. Specimens collected using non-sterile techniques may have microbial contamination.

Specimen Requirements
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 neoplastic fluid using aseptic technique and place in Chromosome Media, available from MLabs. Send at room temperature as soon as possible. Do not allow specimen to overheat or freeze. Do not allow specimen to overheat or freeze. Samples containing <5 million dividing cells, and samples that are greater than 24 hours old are suboptimal.
Additional Information
Appropriate FISH testing will be performed at an additional charge when indicated. FISH testing is available for a number of oncology probes. For additional information on FISH testing and available probes, contact the Cytogenetics Laboratory. By ordering this test the clinician acknowledges that additional reflex testing will be performed and billed at a separate additional charge if indicated.
