Whole genome sequencing is the mapping out of a person’s unique DNA. Your genome is the unique blueprint for your body. Sometimes, because of new or inherited genetic mutations, your genes can cause a disease or increase your risk for disease. By sequencing your genome, health professionals can look at the unique variations found in your genes. It doesn’t predict exactly what will happen, but gives you the chances of something happening. With genome-based testing, health professional can deliver comprehensive answers—accurately and quickly—to many questions about genetic variations and rare diseases. This helps in making genetically informed decisions personalized to patient.
This test requires your blood sample. The blood will be taken from your arm. So it is advisable to wear a something with short sleeves, sleeves of which can be rolled up easily. You do not need to fast or alter your diet before WGS test, until and unless specifically instructed by your doctor to do so. You can eat, drink normally. Make sure you tell your doctor about any specific medication you are taking. Always follow specific instructions given to you by lab. Blood specimen in taking in these quantities:- Adults: 5-10cc Children: 3-5cc Infants: 2-3cc.
•Creating personalized plans to treat disease may be possible based not only on the mutant genes causing a disease, but also other genes in the patient’s genome.
• Genotyping cancer cells and understanding which genes are mis-regulated allows physicians to select the best chemotherapy and potentially expose the patient to less toxic treatment since the therapy is tailored.
• Previously unknown genes may be identified as contributing to a disease state. Traditional genetic testing looks only at the common “troublemaker” genes.
• Lifestyle or environmental changes that can mediate the effects of genetic predisposition may be identified and then moderated.
Few milliliters say; one to two teaspoons of a blood sample would be obtained directly from you. As elastic band will be wrapped around your upper arm to stop the flow of blood and make the veins visible. Area of skin where needle is to be inserted will be cleaned using alcohol Needle will be injected in the vein which is visible. A tube will be attached to the needle to fill it with blood, and blood will be transferred to vessel labeled with your name A gauze pad or cotton ball will be put over the needle site as the needle is removed. If skin swells apply warm press to the needle site.
