The Role of Molecular Diagnostics in Medicine

Some diseases it seems, regardless of how many precautions you take, still strike sooner or later in life – especially if it is programmed into your DNA. For so many years, people who have hereditary conditions could do little but to brace for the possibility of developing the disease and hope that there would be a cure. This is where molecular diagnostics come in.

In this branch of science, professionals analyze the DNA patterns of individuals as well as their DNA's genetic content. Scientists here aim to identify a person's or family line's DNA sequence that has or may bring about genetic mutations that can lead to certain diseases. Moreover, molecular diagnostic studies are also beneficial in identifying specific strains of viruses or bacteria that cause infections.

Through molecular diagnostics, people who are more prone to diseases according to their DNA sequence may take preventative steps to adjust their life decisions and choices, so as to delay, or hopefully, avoid the onset of a disease. Also, some genetic mutations might affect the effectiveness of treatments like therapy and medications. In the future, doctors might be able to customize treatments to meet all the needs of a patient.

If you happen to have a particular genetic mutation in your DNA, remember that it isn’t a hundred percent guaranteed that you will succumb to the condition. With proper testing and lifestyle changes, you can get yourself well on your way to optimum health and potentially avoid the hereditary diseases that might plague your family line.
