Unstimulated short term cell culture and chromosome analysis. Fluorescence In Situ Hybridization (FISH) when indicated.
Identification of chromosomal abnormalities to assist in classification of lymph node tumors. Most lymphomas 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. Necrotic specimens of those older than 24 hours may not grow. Specimens collected using non-sterile techniques may have microbial contamination.

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.
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.
