Chromosomal Analysis

Chromosomal analysis is otherwise called karyotyping. It is a test that detects the number and structure of a person's chromosome for detecting abnormalities. Chromosomes are thread-like structures within each cell nucleus, and they form the body's genetic blueprint. Amniocentesis is a test done in pregnancy to see chromosomal problems and other genetic problems. Karyotypes reveal the changes in chromosome number and other structural changes like chromosomal deletions, duplications, translocations, or inversions.
