Chromosomal Study requires peripheral blood from which lymphocytes are extracted and cultured. Chromosomes in the cultured lymphocytes are studied either in interphase/ metaphase/ prometaphase stage. The metaphase chromosomes are preferred for analyzing the numerical/structural chromosomal abnormalities.
