Genetic screening is the testing of chromosomal DNA,amino acids, proteins to detect the genetic or gene level disease related genotypes, mutations, phenotypes, karyotypes for any clinical purpose. It is very helpful in diagonising a persons future health condition. Genetic testing, also known as DNA testing, allows the determination of the genetic diagnosis of vulnerabilities to inherited diseases. It can provide information about a person genomic structure and their whole genome sequences. In humans, genetic testing can be used to determine a child parentage (genetic mother and father) or in general a person ancestry or biological relationship between other people.
