The accuracy of at-home pregnancy tests vary from woman to woman. It can be frustrating not knowing whether or not you are pregnant right away, especially if you are trying to have a baby. However, not all pregnancy test results are accurate. False negatives can happen because the pregnancy test accuracy is not always precise. It depends largely on your ovulation cycle, the sensitivity of your pregnancy test, and the amount of hCG in your urine when you test. If you are worried about a false negative and the kind of heartbreak that it can provide, educating yourself about the accuracy of different at-home pregnancy tests is in your best interests.
Your body can have a major influence on pregnancy test accuracy. Here’s how it works; pregnancy tests detect hCG in your urine. This is commonly referred to as the pregnancy hormone. Your body begins to produce this hormone once your fertilized eggs implants into your uterus. Once your egg is fertilized, it can take approximately one week to make its way down your fallopian tubes and into your uterus. Sometimes it gets there faster and other times it takes a little longer. Furthermore, the average date of ovulation on an average 28-day cycle is 14 days from the first day of your last period. That means this is most likely the day on which your body releases an egg, allowing sperm to fertilize it. However, not all women ovulate this day. Some ovulate sooner and some later. That means that if your body ovulates a little later than you expect, it could take longer for your egg to implant in your uterus, meaning that a pregnancy test might not show that you are pregnant right away.
Pregnancy test accuracy is also determined based on the date that you test. Some tests are designed to detect even the smallest amounts of hCG in your urine, meaning you can test sooner than your missed period. While most tests are pretty accurate one day after your missed period, experts and medical professionals recommend that women wait to test until one week after their missed period for the best pregnancy test accuracy. However, most women cannot wait that long. Your impatience and excitement might get the best of you, which is why it’s important to know the accuracy rates of at-home pregnancy tests.

The First Response pregnancy tests, both traditional and digital, are the only pregnancy tests on the market that are sensitive enough to let you know if you are pregnant six days before your missed period. However, a negative result this early is not 100 percent accurate as you might have ovulated later than usual or your body simply is not producing enough hCG at the moment. There is a 54 percent chance that you will be able to detect your pregnancy six days before you miss your period with the First Response pregnancy test. On the day of your missed period, the accuracy of First Response jumps to 99 percent.
While it is exceptionally tempting to begin testing for pregnancy almost a week before your period is due, it can cause a bit of heartbreak if your body is not producing enough of the pregnancy hormone needed to show up on your pregnancy test. Even knowing that it’s early and you have a bigger chance of finding a negative result, it’s easy to feel sad. For the best accuracy, wait until one week after your missed period to test. For 99 percent accuracy, take a pregnancy test the day of your missed period. While you might be one of the many women who find out as many as five or six days before your missed period that you are pregnant, you might not want to take a negative result seriously until the day of your missed period.
