Clearblue Digital Pregnancy Test: A pregnancy test that shows on its screen how many weeks pregnant you are when the result is positive. It is used for self-diagnosis of pregnancy, and has a screen that accurately indicates whether or not you are pregnant, and also how far along you are (if the result is positive). This pregnancy test works by performing two analyses: First, it detects the presence of pregnancy hormones in the urine, with an accuracy of over 99%; and in a second analysis, it indicates how many weeks have passed since conception: 1-2, 2-3, or more than 3 weeks. Thus, the digital screen of the Clearblue digital test shows clear results, with the words "Not Pregnant" appearing if the test is negative, and "Pregnant" and the number of weeks if it is positive. Provides results up to 5 days before the first missed period. For women who want to know whether or not they are pregnant, and how far along they are. Follow the instructions for use that appear on the product. Use with a urine sample.
