Chromosomes are present in every cell of the body. These
chromosomes carry the DNA information that defines many aspects
of an individual's life. DNA evidence is used to determine if
the individual will develop normally or not. There are a few
genetic abnormalities that may be caught at an early stage of
pregnancy. The tendency is to suggest that such pregnancies be
terminated as they would only lead to the development of
children who are born with abnormalities. The karyotype test is
used to collect the information needed relating to the health
and functioning of the chromosomes. There are several steps that
need to be followed in order to perform the karyotype test. The
sample is collected from a newborn baby or from the amniotic
fluid of a pregnant woman. The entire karyotype test procedure
requires one week to be performed. This is because the cells
need to be collected and then divided and allowed to grow. When
these cells grow in the laboratory, the doctors can identify the
necessary genetic information
