A new AI-powered blood test that can detect 12 types of cancer is to be tested on NHS patients. Using this test, experts would now be able to detect cancerous cells in people much before the symptoms appear. The trial, conducted on 8,000 patients, will analyse blood samples for tiny fragments of genetic material released by tumours. The test called miONCO-Dx, was created using data from 20,000 patients. Initial tests have produced promising results, having shown that it can detect 12 of the most lethal and common cancers, including bowel cancer, at an early stage, with over 99% accuracy. With no other trial currently working in the same way, this is a world-leader and will support in placing Britain at the forefront of revolutionising healthcare. Notably, the UK government has awarded £2.4m to run the trial of the genetic test, which was developed by the University of Southampton and the biotech startup Xgenera. How Does It Work?The test was created by Xgenera, in collaboration with the University of Southampton. As little as 10 drops of blood are all that's needed to detect up to 12 common cancers. The test works by measuring the microRNA in a blood sample and using AI to identify if cancer is present and, if so, where it is located in the body. What Cancers Will It Detect?Lung, gastric, prostate, oesophageal, liver, bladder, ovarian, bowel, pancreatic and breast cancers–as well as bone and soft tissue sarcoma and a type of brain tumour. The Department of Health said the test was now ready for the "validation and verification" stage.Professor Sir Stephen Powis, NHS England's national medical director, said: "This blood test has the potential to help us detect bowel cancer earlier and reduce the need for invasive tests, and the next step in this trial will now be vital in gathering further evidence on its effectiveness and how it could work in practice."How Is A Blood Test Conducted?A blood test is a simple medical procedure used to check various health conditions. Here's how it is typically conducted:1. Preparation: Depending on the test, you may be asked to fast for 8–12 hours. The healthcare provider will explain any specific instructions.2. Collection: You’ll usually be seated or lying down. A healthcare professional will tie a tourniquet around your upper arm to make the veins more visible. The inside of your elbow is the most common site for drawing blood.3. Cleaning: The area is cleaned with an antiseptic to reduce the risk of infection.4. Drawing Blood: A sterile needle is inserted into the vein, and blood is collected into one or more vials or tubes.5. Post-collection: Once enough blood is collected, the needle is removed, and a cotton ball or bandage is applied to stop any bleeding.6. Processing: The blood samples are then sent to a lab for analysis.
