Is It Really Melena
Distinguishing between Upper and Lower GI Tract Bleeds
Photo of the Blue Blood Scanning Box and test tubes with color changing indicator for an upper GI bleed. Here, a test tube containing simulated upper GI blood from a stool sample and color indicator is inserted on the top right of the Blue Blood Scanning Box. After the test tube is inserted, the Blue Blood Scanning Box takes a picture of the test tube. The device analyzes the image and based on pre-set parameters from testing, the device outputs “Upper” indicating that this sample most likely is an upper GI bleed.
