Each cell in human body has 46 chromosomes (23 from mother and 23 from father) that are made from DNA or Deoxyribonucleic Acid. Not to mention Genes that are short sections of DNA and each chromosome include uncountable number of genes that contain information about the body structure and need to make chemicals or proteins from the structure. It also plays a pivotal role in processing to keep human alive. What makes all individuals different are genes that are the basic unit of your genetic material? However, possibility of changes in genes cannot be denied and that may result in genetic disorders or different types of diseases.
Genetic Testing – What Is It and Why Is It Important?
Here, genetic testing plays an important role to identify the changes in chromosomes, genes and proteins. Genetic tests are done to find out the real use and structure of DNA. Put simply, such tests are done to identify the gene that may cause genetic disorder. Such tests are done to look for abnormalities in DNA taken from the blood, body fluids or tissues of human body. Such tests are also ideal and important for ladies who are carrying pregnancy to determine the risk of genetic disorders and take the right steps to prevent them passing in your kids.
Genetic tests help specialists to examine a person’s DNA in a variety of ways; while they are designed to identify differences between the gene being tested. Other tests look for small changes within the DNA. Other mistakes that can be found include genes that are too active, genes that are turned off, or those that are lost entirely.
Different Types of Genetic Tests to Determine the Risk of Genetic Disorders
Genetic testing procedures are divided into different categories that include:
Molecular Genetic Test – It is done after taking the single genes or short lengths of DNA taken from blood, saliva or tissues to identify the large changes and small changes like missing, altered parts within the DNA strand.
Chromosomal Genetic Tests – Such tests are important to know about the features of a person’s Chromosomes, structure, number and arrangements. Such tests are undertaken in different ways that include karyotyping, fluorescent in Situ hybridization analysis and others.
Biochemical Test – it is done to look at the activities of key proteins. According to healthcare specialists, genes contains the DNA code for formulation of Proteins, activities of proteins and others. They are ideal for genetic screening in Newborn babies. This type of test can defect infants with condition that affects one of the many essential chemical reactions in the body.
GeneticTesting is performed in different ways to identify the risk of genetic disorders and prevent them passing in the next generation. Some of the common ways of such tests include:
- Newborn Screening and Diagnostic Testing
- Carrier Testing and Prenatal Testing
- Pre-implantation Testing
- Predictive Testing and Forensic Testing
In pregnancy, same for such tests is taken from the baby by chorionic villus sampling and amniocentesis. In newborns, routine genetic screening is done for genetic disorders. You need to reach a healthcare center where such tests are done to ensure good health and well-being of your newborns.
