Pregnancy tests work by detecting the pregnancy hormone, HCG, in the urine or blood. The hormone is only present when a woman is pregnant. If you think you may be pregnant, taking a pregnancy test as soon as the first day of your missed period can help you get the care and support you need. A home pregnancy test can tell whether you are pregnant with almost 99% accuracy, depending on how you use it. If a pregnancy test says you are pregnant, you should see your doctor for another test to confirm the pregnancy and talk about next steps. We conduct safe and secure pregnancy testing that is accurate and authentic. It is also completely complimentary and confidential.
