Israeli saliva test startup develops first-ever saliva-based pregnancy test. It uses a simple hand-held applicator to collect a saliva sample, which is inserted into an assay device and produces results within ten minutes.. Traditionally, two lines mean a positive result, and one means a negative one.. The test shows the level of human beta-chorionic gonadotropin (? -hcg). It is a hormone that usually appears in the saliva of pregnant women from about three to four weeks of pregnancy, \? -hCG is commonly referred to as the hormone of pregnancy. When a fertilized egg is implanted in the uterus, the placenta begins to produce this hormone, which usually rises steadily in the first weeks of pregnancy.. Clinical trials on over 300 women have shown the test to be about 95% accurate when used from the first day of a missed period.. Plus, the included app allows you to share your results digitally, eliminating the hassle of traditionally photographing a test stick.. We will remind, earlier the mother of four children British Sarah Bailey did not suspect that she was pregnant with her fourth child.. She found out about it already when she started giving birth.. Archaeologists have found a pregnancy test that is 3,500 years old. Subscribe to our channel https://t. me/korrespondentnet Author: 1.
