A genetic health test is carried out in order to determine which kind of genetic disorders a person is at risk of suffering from in future. This helps in making decisions on how to stay healthy by adjusting the lifestyle and engaging in healthy activities such as exercise and taking better diet. The dna test involves studying of a person's DNA so as to identify the occurrence of any disease-causing mutations in his or her genes and it is done by a professional doctor.


Before taking this genetic health test, it is important that a person is able to talk to a doctor who can advice them and inform what the test results might mean. This because the person should be ready and understand what negative implication might be brought about by the test results in case they come out positive of whatever is being tested. They should be ready to make the necessary adjustments to their lifestyle if need be.


The test is done by taking a sample of a person's blood and then keenly analyzing the gene variations and structure to identify if there are any inconsistencies which indicate the existence of a trait that is undesirable and might cause a disease with time. These traits might not be removed but the right kind of changes can be made by the person as advised by the doctor to reduce chances of sickness.


The people that are at high risk of getting these diseases are mainly those whose parents, grandparents or other close relatives might also have suffered from the disease. This is because some of the traits and mutations that cause some diseases are inherited down a generation through the special genes. These health conditions may also include some allergies, reaction to some drugs as well as ability of the body to fight some diseases.

With the knowledge of possibility of being at risk of getting a disease due to ones ancestry, a person might buy their own home dna testing kits and with available guidance on the equipment manual and other information, they can test themselves and identify their own risks to getting diseases and how or what to do to prevent such diseases.



Apart from the identification of health risks and mutations in a person's DNA, DNA profiling can also be used to study a person's genetic patterns which help to identify them uniquely and it can also be used for criminal identification by DNA fingerprinting, paternity as well as maternity tests and identifying dead bodies.
