Chromosome Analysis, Lymph Node
Also known as: Lymphoma Karyotyping
Use
Identify specific chromosomal abnormalities associated with non-Hodgkin's lymphoma
Special Instructions
Indicate tentative diagnosis on the test request form. This is necessary for proper culturing and result interpretation. Please do not submit hypocellular fine-needle aspirates (FNAs) for chromosomal analysis. Target FISH analysis is recommended for hypocellular FNAs. For questions regarding this test, contact oncology customer service at 800-345-4363.
Limitations
FNAs are frequently unsuccessful and may not provide sufficient material for chromosomal analysis. Normal lymph nodes, which are often nonmitotic, may also yield no results. Therefore, it is recommended to perform this test on properly prepared lymph node specimens.
