Arthur Queval's, Qloudlab's CEO, father had a stroke, but there wasn't a concentration of technology in smartphones/tablets that could be useful for medical applications, so he came up with the idea to turn the electric field generated by the touchscreen to perform blood diagnostic testing.

"A diagnostic tool that uses a smartphone screen to perform blood tests has been developed by a microengineering laboratory at the Swiss Federal Institute of Technology (EPFL)," (Solon wired.co.uk). Within minutes, this tool has been developed and modified to ensure at-home blood analysis for people experiencing anticoagulant treatment. People are treated with anticoagulants to prevent blood clots from forming in arteries or veins. Blocked arteries stop oxygen from accessing a specific part of the body and can lead to a stroke or a heart attack of pulmonary embolism. Pulmonary embolism is a common and potentially deadly disease that occurs when veins become blocked. When patients are taking anticoagulants, they need their blood flow to be regularly monitored, which usually occurs in a hospital; however, this new system can produce test results using a smartphone screen, meaning that patients won't have to travel to a hospital as often. The latest prototype uses a Samsung Galaxy S4, but Queval is self-assured that the team can assemble the system on other models. A drop of blood enters the film through a capillary action, which is the tendency for a liquid to rise and fall as a result of surface tension. It then comes into contact with a molecule that makes the blood coagulate-thicken. An app on the phone taps into the capacitive field on the screen to observe disruptions. Changes in the field produced by the path of the blood in the film can be analysed to produce results. The object is to see that the patient with thinned blood isn't at an increased risk of bleeding. This system is also modified to test for other blood-presenting conditions, such as looking for blood glucose levels in diabetics. This technological advance can correlate with biology, as it twines with blood and organs of the human body, and also AP Human Geography, due to the team wanting to commercialize the product by 2015 in order to diffuse the contraption throughout the world.

As people are experiencing circulation-mobility that occurs on a daily basis-there is hardly enough time to check in at a hospital and receive a check-up. This breakthrough makes it highly convenient. In the modern world, you can access just about everything through your smartphone: your alarm system, bank, fitness level, the internet, time, a camera, and now your blood levels. I can certainly tell you that there is not enough hours in the day for me accomplish every task I need to acquire. A trip to the hospital just makes the objective even harder to accomplish. I am not surprised at all that people can now access their present blood level using their smartphone. Nowadays, people ask the question, "What can your smartphone not do?" Technology is advancing day by day, and a simple app can now solve many problems. I have a grandfather who is undertaking diabetes, and he has to proceed through check-ups of his blood levels. There are times when this is highly inconvenient, and he is retired, so I would imagine it is onerous for a middle-aged, working citizen to find time to go to the hospital. Not to mention the waiting time is quite long. This new feature can also help someone through a time in need. Many people develop strokes or certain diseases because they do not survey their health level. That's how Arthur Queval's father died, which inspired him to make this app. This new system can help prevent an occurence like this, and I am forever grateful for that because this could be a commodity that helps save my parents or another family member one day. Arthur is making a change that enhances the world day by day, and I hope that I can do my part in the world by saving someone day by day. I can not wait to see what's in store when I start to work in the medical field.
