In this world of advanced medicine, genetic testing is still one of the best way to diagnose many diseases that usually take time to figure out in your body. In genetic testing or DNA testing, the genetic condition of your body is scruitinsed by taking blood samples and enables your doctor to identify the real reason and help you through any difficult time. The following are the different type genetic tests.
Diagnostic testing: In this, you undergo a test which will help the doctor identify the problem or disorder in your body, especially if you have physical symptoms such as Huntingtons disease in which your brain’s cells die out gradually. Through diagnostic testing, the doctor can track your health records since your birth, making it easier for him to plan your health care and also deal will the future ramifications of your disease. Interestingly, diagnostic testing can be done at any point in your life.
Prenatal testing: In this DNA testing, the doctor will be to identify any changes in your child’s genes before he is born. Since prenatal testing is done while you are pregnant, you can make a conscious and informed decision about your pregnancy once your doctor detects or rules out any disorder. In addition, if you are having a high risk pregnancy, then this testing will help you plan better as your due dates nears. Moreover, if there is disorder detected, then you will be able to prepare for your child’s birth by taking steps to ensure he becomes acquainted to the world in a better way.
Predictive testing: In this, you will undergo a test only if there is a family member who is suffering from a specific disease like cancer. For example, if your mother was diagnosed with cancer and but you have not shown any signs of it, then you can undergo predictive DNA testing. In predictive testing, the doctor will able to tell you if you would risk developing cancer in the near future. As a result of which, you will be consciously aware of your medical history and not take any medical problems lightly.
There is also process of Dna profiling is used to bring out which goes deep into the hereditary of the person. In presymptomatic testing, even before you start having those similar symptoms that your parent or your relative had. As a result of this, you will be able to avoid this disorder throughout your life with careful health plans.
Preimplantation testing: In this, a few cells from the womans embryo are taken and observed for genetic changes that could lead to disorders in the child. This testing can be done during in-vitro fertilisation, in which, the ovaries are fertilised with sperms through external processes. If there is a change in the embryos, those ovaries are discarded. Only the ones without any changes are implanted to enable pregnancy. Preimplantation allows the doctor to reduce the risk of any disorder.
Forensic testing: Identifying a body which is charred beyond recognition or is a John Doe is what DNA testing allows. In this the basic recognition of the person through the data base can help identify them if they are dead or victims of an attack. It is the fastest way to recognise them.
