The Alvita Pregnancy Test is a rapid and accurate test, allowing users to carry out a fast pregnancy test in their own homes during the very early stages of a potential pregnancy. A result is available in just one minute, with the test checking for the presence of the human chorionic gonadotropin (hCG) hormone, which appears in urine during the earliest stages of pregnancy. The test can be used at any time of day from the onset of menstruation, and is 99% accurate. It is recommended to use the test with the first urine passed of the day, in order to achieve the most accurate results.
