Diagnosis

Researchers at Florida Atlantic University (FAU) have created a cheap and simple biosensing platform that is able to detect the presence of various types of harmful bacteria and viruses in a single drop of blood. When used in conjunction with a smartphone, the system offers the potential of diagnosing diseases in remote locations from anywhere in the world. Read More
Typically, tests for diseases must be done one disease at a time, and can take days to be processed through a lab. A new device developed in an EU project, however, can test for several diseases at the same time and provide results within an hour. The LabDisk is designed for use in Africa. Read More
While blood tests are used to rule out other forms of arthritis, the diagnosis of osteoarthritis (OA) generally relies on physical symptoms, with X-rays or MRI scans used for conformation if required. But researchers at the University of Warwick in the UK have identified a biomarker for OA that could lead to a blood test that could diagnose it, and rheumatoid arthritis (RA), years before physical symptoms present themselves.

The development of brain plaques are thought to correlate with symptoms of Alzheimer’s disease, such as memory loss. Previous research has indicated that limiting these buildups could be the key to tackling the disease, but scientists from Northwestern University are digging a little deeper. The team has devised a non-invasive MRI technique capable of tracking the specific toxins that accumulate to form plaques, potentially enabling doctors to pick up early signs of the disease before it starts to take hold.

One of nature’s most notorious psychopaths may be giving cancer patients new hope. The mantis shrimp is famous for having a punch like a .22 bullet and a perpetual bad attitude, but is also has the most complex eyes in the animal kingdom, which are excellent at detecting polarized light. With this in mind, the University of Queensland is developing new cameras based on the mantis shrimp’s eyes that can detect a variety of cancer tissues. Read More
Diagnosing depression can be a difficult task, currently relying on patients reporting symptoms – something those suffering depression don't always do – and doctors correctly interpreting them – which isn't easy as the symptoms are non-specific. Now researchers have developed a blood test to diagnose depression in adults, providing the first objective, scientific diagnosis for the condition. Read More
Gizmag recently caught up with Team Aezon members Krzysztof Sitko and Neil Rens for an in-depth discussion of their finalist entry to the Qualcomm Tricorder XPRIZE. The competition aims to stimulate advances in the field of diagnostic equipment, with the incentive of a US$10 million prize purse. Such technology has the potential to revolutionize the speed and accuracy with which a diagnosis can be made outside of a hospital environment. Read More
If a child who's simply very active is mistakenly diagnosed with Attention Deficit Hyperactivity Disorder (ADHD), they can end up on pharmaceuticals such as Ritalin unnecessarily. The problem is, it can be quite difficult to determine if someone actually has ADHD, and misdiagnoses are common. Now, however, researchers from Tel Aviv University have announced that analyzing a patient's eye movements may be the key. Read More
Although many dread the prick of a blood test, most would find it a preferable testing method to invasive and expensive biopsies. That's why a blood test for cancer is the goal of many research efforts, including one at the University of Bradford in the UK, where researchers are claiming to have devised a simple universal blood test for the disease that relies on the fact that white blood cells in cancer patients are already damaged from battling cancerous cells.

An international collaboration of scientists led by King's College London (KCL) and Proteome Sciences plc has identified a combination of 10 proteins found in human blood cells which may lead to an accurate early warning test for Alzheimer's. An increased ability to detect this debilitating disease at an early stage has the potential to greatly improve quality of life and may even lead to new clinical trials developing new avenues of treatment designed to stop the disease in its tracks.
