CHROMOSOMAL ANALYSIS LYMPH NODE OR EXTRANODAL TISSUE FOR LYMPHOMA
Karyotype - Karyotyping - Chromosomes - Chromosome Study - Cytogenetics
Chromosomal abnormalities may assist in the identification and classification of malignant tissues
Specimen Collection Requirements
Biopsy and/or an Intact Lymph Node
Use sterile technique. Place specimen in a screw top container and cover with sterile Hanks BSS, normal saline or RPMI transport media. The volume of transport media should be sufficient to keep the specimen from drying out. Do not expose to, or place in, formalin. The specimen needs to be processed the same day as collected and always within 24 hours. STAT delivery is recommended. See Cytogenetics/Flow Cytometry/FISH Specimens for Leukemia, Lymphoma and Other Oncology Referrals.
Approximately a 1.0 cm3 specimen
SPECIMENS SUBMITTED IN OR EXPOSED TO FORMALIN. Rejection is only at the discretion of the Cytogenetics Laboratory.
Ambient: 24 hours; Refrigerated: Suboptimal, call Cytogenetics Lab at (503) 413-4613
Clinical information including the indication for study must accompany the specimen. Requisition forms for cytogenetics studies are available upon request.
Classical G-Band Chromosomal Analysis
Cytogenetics interpretation provided. A computer generated karyotype is also provided with each study.
46,XX [number of cells analyzed], apparently normal female
46,XY [number of cells analyzed], apparently normal male
