Stanford’s Automated Dipstick System Takes Errors Out of Urine Testing
http://www.medgadget.com/wp-content/uploads/2016/05/urinalysis-machine.jpgWhile urine dipstick tests are some of the easiest diag**stic tools physicians have, they can often be misleading if a poorly trained person does the test. Moreover, lighting and other factors can make colors seems **t what they are and skew the results significantly.
At Stanford University researchers have been working on an easy-to-use device that can essentially automate the entire process and even read the results for you. It’s a black box with a mechanism that separates a urine sample into ten identical amounts and places those into ten holes at the bottom of the box. Each hole, just like on a traditional dipstick test, tests for a unique chemical biomarker. Once the sample is delivered, the user places the phone on top of the box and starts the matching app. The app takes a picture of the test and interprets the colors all on its own.
The standardized*illumination from*the smartphone’s LED light helps to make sure the test is well calibrated and results are accurate.
Here’s an animation showing the workings of the device:
