Routine Cytogenetics: Evaluation of chromosomes for detection of cancer-related abnormalities: Involves analysis of a minimum of 20 banded metaphases from two separate cultures; preparation of representative karyotypes from all cell line.
	Heteromorphism Analysis: Documentation of normal chromosomal differences between patient and the intended bone marrow donor. Such heteromorphic differences serve as markers of engraftment following sex-matched bone marrow transplants.
Fluorescent in situ hypbridization (FISH): The following FISH probes are available for evaluation of specific chromosomal regions or specific genes.

	centromere probe (available for each chromosome): useful for abnormality of chromosome number. Example: trisomy 8
	chromosome paint: detects entire chromosome; useful for structural abnormalities.
	Specific oncology probes: M bcr/able m bcr/able t (15;17) iso (17q) p53 HER- 2/new N-myc Retinoblastoma p58

These tests can be performed on a number of specimens as listed here.
