The information contained in the genes determines appearance, influences personality traits, likes and dislikes, and abilities. They affect the extent of predispositions to certain diseases or disorders. Thanks to genetic testing experts can now discover the secrets of our DNA, and suggest preventive treatment options. Sometimes the knowledge gained from genetic testing pertains not only to the patient also to future generations. More and more couples suffering from infertility are looking for the causes of their problems in the genes.
Patients unsuccessfully trying to conceive a baby who start specialized treatment, may choose to perform a genetic test. The tests are recommended especially for women over 35 years, couples who are preparing for the in vitro treatment, and those who have experienced recurrent miscarriages. Another group of patients that may benefit from genetic testing are those who have a history of genetic disorders in the family.
Clinical geneticist or infertility treatment specialist will help to plan appropriate diagnostic tests. Interview and examination the patient’s situation will guide the decision as to what tests should be considered. Either blood or saliva may be tested.
Increasingly Internet mail-order genetic test kits are becoming more available. Patients can order them from home, take a saliva sample and send it to the lab. However, before buying a test, it is worthwhile taking a careful look at the laboratory that performs the test.
Experience of the laboratory and the methods it uses should be considered while making the decision. Genetic studies are the fastest growing sector of medical diagnostics. The research methodology from 10 years ago has already been superseded by its successive generations. The newer molecular biology tool is used, the better the quality of research. Employment of highly trained staff and an independent molecular biology laboratory are important prerequisites for obtaining the highest quality of genetic testing. In such conditions, the methodology is continuously updated, and the wait time for the results is shortened to just a few days – explains Sebastian Pukszta, PhD, Manager of Invicta’s Molecular Biology Laboratory.
Currently, the method considered to be the most reliable tool for DNA analysis is the next-generation sequencing (NGS).
