Genetic factors sometimes play in role in the development of prevalent non-communicable diseases like diabetes and cancer. In some cases, these health risks can be identified early through genetic testing, a process that examines one’s DNA to detect changes that can increase risk of diseases. It can often prove useful in diagnosing genetic conditions and assessing risk of future diseases.
Dr Pranav Gupta, Consultant and Head, Molecular Biology Regional Reference Lab at Apollo Diagnostic Delhi, explains, “Genetic testing is an effective tool that provides valuable insight into one’s health by analysing DNA and confirming whether one has a birth defect, chromosomal disorder or hereditary cancer.”
Further sharing how DNA can help diagnose health risks, he says, “DNA acts as a blueprint of your body. It holds information that helps determine everything from your physical traits to the risk of being diagnosed with certain diseases. Genetic testing can reveal if you have inherited any health issues or conditions or are at risk of developing the same. This can include hereditary conditions like diabetes, cancer or cardiovascular diseases. With the help of genetic testing, your doctor may also understand your body’s way of responding to certain medications. By uncovering these insightful details, genetic testing encourages individuals to make informed decisions about their physical well-being, and overall lifestyle.”
