First Response and Modern Fertility can both detect pregnancy up to 6 days before your missed period. However, it’s important to note that the accuracy isn’t as high. It’s still ideal to test after your missed period for the best results. Most at-home pregnancy tests can be up to 99 percent accurate on the day of a missed period. Which week in my cycle should I take a pregnancy test? Be careful about the hCG strip turning pink of the Clearblue Easy Pregnancy Test with color changing tip. Despite small differences between them, all over-the-counter pregnancy tests work basically the same way. They detect a hormone called human chorionic gonadotropin, or hCG, in urine, which the body starts producing when a fertilized egg implants in the lining of the uterus and an embryo begins to grow. Even urine-based pregnancy tests used in doctor’s offices tap the same mechanism. “Anything that’s detecting the pregnancy hormone from the urine is going to be the same, whether you get it from us, or if you get it from a drug store test that you take at home,” says Dr. Sarah Horvath, an obstetrician-gynecologist at Penn State Milton S. Hershey Medical Center.

The First Response pregnancy test’s sensitive technology can detect a low level of the hCG pregnancy hormone, helping you get an accurate result early in your pregnancy. Tell Me Baby readers find these tests easy to use, accurate and found the lines easy to read. Cons

The level of the hCG hormone doubles after every 48 hours. The hCG antibodies (particles that can detect urine hCG) are present on the test strip. On the day of her missed period, a pregnant woman will have an hCG concentration about 100mIU, which should be easily detected by all pregnancy tests. Mumsnet has been helping parents make their lives easier since 2000 and, in those years, we’ve seen, tried and reviewed thousands of products. The test strips are easy to use—just dip the test into a cup of urine for five to 10 seconds, then wait five minutes—and easy to read, with clear, dark lines that indicate pregnant (two lines) or not pregnant (one line). Pregnancy tests detect the pregnancy hormone human chorionic gonadotropin (hCG) through your urine (or blood if you visit the doctor’s office). “Pregnancy tests are approximately 99 percent accurate [and] best utilized after a missed period,” says Kecia Gaither, MD, an OB/GYN, maternal-fetal medicine specialist, and director of Perinatal Services and Maternal Fetal Medicine at NYC Health and Hospitals/Lincoln in the Bronx. “False positives are rare but can occur."

Like other tests, if you wait until the day of your expected period, the accuracy jumps to 99 percent. Pregnancy tests are designed to identify hCG, either in blood or urine, according to the U.S. Food and Drug Administration (FDA). Once the fertilized egg implants in the uterus, your body begins producing hCG. A blood test can tell if hCG is present and the amount. This pregnancy hormone is also passed in your urine, making home pregnancy tests an excellent alternative to in-office blood tests. But, home tests are not as sensitive as a blood test and require waiting to test. During the first trimester, the pregnancy hormone increases from less than 5mIU/ml to over 100,000mIU/ml, and the further into your pregnancy you are, the more present this hormone will be in your urine.
