5Pcs High Sensitive Pregnancy Test kit Tests strip

* Our Pregnancy Test Strips are over 99.9% accurate and are capable of detecting human chorionic gonadotropin, or hCG, at levels of just 25mIU/ml/hCG. That means you can begin testing accurately just 6 to 8 days after conceiving - and days before your missed period. Easy-to-use, and extremely sensitive for early detection of pregnancy - these are the same tests used at your doctor's office. Our tests are individually wrapped, offering the full 2-year expiry date. Begin testing as early as 7-10 days past ovulation. To use the pregnancy test strips you simply fill a container or a collection cup with urine and hold the test strip in the container in a vertical position. Just dip the tip of the test for a few seconds. Your results appear in just 1 minutes. * How Does pregnancy test Work? Human chorionic gonadotropin (hCG) is a hormone produced by the developing placenta shortly after the conception and secreted into the urine. The pregnancy test contains antibodies which specifically react with this hormone. When the strip is immersed into a urine specimen, capillary action carries the specimen to migrate along the membrane. When hCG in the sample reaches the test zone region of the membrane, it will form a colored line. Absence of this colored line suggests a negative result. To serve as a procedure control, a colored line will appear at the control zone region, if the test has been performed properly.
