Chromosome Analysis, Tumor/Pleural Effusion/Ascites fluid, for Neoplastic Disorders

Chromosome Analysis, Tumor/Pleural Effusion/Ascites fluid, for Neoplastic Disorders
WSLH Department: Cytogenetics
WSLH Test Code:836
CPT Code: 
Price: 
Includes:G-banded chromosome analysis of unstimulated, spontaneously dividing, tumor cells. Includes short term culture of cells from tumor or effusion, examination of at least 20 metaphase cells (when possible), and preparation of two karyograms. Additional cells may be examined if indicated by initial results. Additional karyograms may be prepared if multiple cell lines are observed. Quality and number of cells analyzed may be limited if specimen is not adequate.
Methodology:**(CPT Codes: 88239, 88264, 88280)** Microscopic analysis of G-banded chromosomes.
Availability:Monday-Friday 7:45 AM - 4:30 PM, Saturday 7:45 AM - 12:00 PM
Turn-around Time:Approximately 6-8 days. (For tumors that grow as monolayers additional time for culturing may be required.) (Reports are issued Monday-Friday 7:45 AM - 4:30 PM)
Recommended Uses:Identification of chromosome abnormalities associated with hematologic disorders (such as leukemia and lymphoma) and neoplasias.
Contraindications: 
Specimen Requirements:Tumor sample at least 0.3 cm cubed; 10-20ml of pleural effusion or ascites fluid
Collection Kit/Container: 
Patient Preparation: 
Collection Instructions:**A 0.3-1.0cm cubed section should be collected using aseptic procedures; avoid areas of necrosis. Place the specimen in a sterile tissue vial containing transport media.
**Collect the fluid under sterile conditions. Dispense 10-20 ml of the fluid into two sterile 15 ml centrifuge tubes or a sterile specimen cup.
Specimen Handling and Transport:Store and transport specimens at room temperature (may transport with coolant during hot, >85 degrees F weather). DO NOT FREEZE. The laboratory must receive specimens within 24 hours of collection.
Unacceptable Conditions:Samples must not be frozen or processed with formalin.
Requisition Form:Cytogenetics Lab Neoplasia Diagnosis Form #132
Required Information:Laboratory regulations require the following minimum information to be provided on the requisition form for a specimen to be accepted for testing: Patient name or unique identifier; date and time of collection, patient date of birth and sex, specimen type/site of collection, test request(s), reason for referral, clinician name and UPIN/NPI, and address for reporting results. Please be certain that name/identifier on the form matches that on the specimen label.
Results include:Karyotype written using International System for Human Cytogenetic Nomenclature (ISCN) 2013 and interpretation of results.
Limitations:Analysis is dependent on the presence of actively dividing tumor cells in the specimen.
Additional Tests Recommended:Fluorescence in situ hybridization analysis may be recommended to characterize chromosome abnormalities; if performed there will be an additional charge.
