WebCytogenetic analysis is the study of the banded pattern of chromosomes during metaphase of the cell cycle. It is carried out on a cell-by-cell basis, and hence mosaicism is easily recognized when only a few cells carry the chromosomal abnormality. This analysis can detect large-scale chromosomal abnormalities, most commonly aneuploidy. WebCytogenetic analysis remains one of the standard methods for detecting abnormalities in tumor chromosomes and includes techniques such as karyotyping and analysis of G-banded chromosomes and FISH. Testing is performed using specimens containing viable cells such as peripheral blood, bone marrow, or tumor tissue.
