What is a DNA Test? DNA testing, also known as genetic testing, is the process of identifying your genetics. DNA or chromosomes are a genetic element that holds your code of life. DNA is present in our cells, and all of them have the same DNA code. But each person has a unique and different DNA code that distinguishes them from each other. DNA is transferred from generation to generation. You get your DNA from your biological parents.

DNA testing helps to understand genetic changes such as RNA analysis or biochemical analysis. Genetic testing helps in diagnosing medical conditions to rule out the treatment of diseases. It determines the biological family relationship by using different test techniques like paternity testing, maternity testing, or twin testing. We can also predict a person’s ancestors through genetic testing.

Types of DNA Tests

DNA testing provides information on DNA, metabolites, and proteins to determine diseases for clinical purposes. It gives information about the genes and chromosomes. There are many types of DNA. Some of them are:

·       Newborn Screening

This test provides an early diagnose of the genetic disorders of a newborn for the treatment.

·       Diagnostic Testing

This test diagnoses a specific genetic condition. It usually confirms the diagnosis a doctor makes by looking at the symptoms.

·       Carrier Testing

It identifies the person who carries one copy of gene mutation. If two copies of gene mutation combined, it leads to genetic disorders.

·       Predictive and Presymptomatic Testing

It identifies the gene mutation that appears after birth. This test will help those who have a family member of genetic disorder but also predict gene mutation for them who have no symptoms of the genetic disorder at the time of testing.

·       Paternity Testing

Paternity test compares your DNA with your biological father to confirm your relationship. You inherit DNA half from your father and a half from your mother. Scientist compares the DNA to find the match of DNA sequence.

·       Genealogical DNA Test

This test identifies your genetic heritage or ancestors.

·       Research Testing

Research testing is common for the research study, and they don’t show results to the patients. This test finds out unknown genes, develops a better understanding of genetic conditions, and learns how genes work.

Apart from the DNA test mentioned above, many other tests are used according to their need.

The DNA Testing Procedure

DNA testing is a science, and it requires technology and method. Your DNA goes through an extensive process to give you DNA test results.

·       Sample

The first step is to collect a sample. The sample can be blood, hair, skin, and amniotic fluid. The most common method is the buccal swab. It takes a sample from the inside of your cheek.

·       Lyse Cells

After collecting cells, the next step is to break the membrane of the cells. Mostly, an enzyme is useful to break the cell membrane.

·       Separation

To separate DNA, the membrane of a cell needs to break. There are many methods to separate DNA from the sample but the most common is electrophoresis. This method is performed by using an electric field to separate molecules in the sample. This way, DNA molecules drives away from the rest of the sample.

·       Copying

A method called PCR is used to develop copies of the DNA. These copies then examine for genetic researchers.

·       Testing

After copying, the DNA is tested to identify genetic markers to determine the relationship. Your DNA consists of thousands of genetic markers. The DNA relationship test reports on 16 to 20 specific genetic markers can prove a genetic relationship.

·       Matching

After obtaining genetic markers, they are matched with other DNA samples. This helps you identify the person with the DNA sample. If it is a paternity DNA test, half of the child’s genetic marker should come from the father, while the other half should come from the mother.
