According to the new study, only a simple tube, some software and saliva samples were needed, and experimenters and their doctors could measure the cortisol levels of the stress hormones presented by Ice Endo of the Chicago Endocrinology Society and the Endocrine Syndrome Society.
"We have designed a method by which any smartphone will be able to quickly measure their saliva cortisol levels, conveniently and inexpensively," said Dr. Joel, chief investigator of diabetes and endocrinology in Utah. In the United States, a commercial laboratory charges up to $50 for saliva cortisol testing, and it takes a week to deliver results. Smartphone testing will cost less than $5 and results in less than 10 minutes. The United States and other areas of the world that lack equipment can measure cortisol. In addition, the technique of measuring saliva cortisol will consume less cost and time because the test does not require complicated infrastructure and well-trained technicians.
