Chromosome Analysis, Lymph Node
Also known as: Lymphoma Karyotyping
Use
Identify specific chromosomal abnormalities associated with non-Hodgkin's lymphoma
Special Instructions
Not provided.
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.
