Most of the low to medium income, developing nations are many times deprived of medical and other healthcare facilities, due to several reasons such as distance between the patient and healthcare service providers and others. Researchers have devised an important solution to this by creating medical diagnostic applications that are really small and can fit into the objects that people are already using in their day to day life. Cell phones were identified as one such object that can bring the hospital to the door or in the hand of the patient. Some of the emerging cell phone-enabled diagnostics include, cell-phone lensfree microscope, cell-phone based imaging using microchip ELISA, mobile phone based clinical microscopy, cell-phone based platform as a biomedical device and telemedicine tools using mobile phone cameras along with paper microfluidics. Some of the examples of these cell phone-based diagnostic tests applications are Roche's Accu-ChekA Glucose Buddy, which is an iPhone application and Arkray's Smart e-SMBG, which is an android application. Tests for sexually transmitted diseases and many other infectious diseases are in huge demand worldwide, which are in their developmental stages at different universities and companies. The cell phone-enabled diagnostics market can be classified into five major segments, namely, cell phone-enabled diagnostics for diabetes, cell phone-enabled rapid immunoassays, cell-phone enabled microscopy, and cell phone-enabled molecular tests.
