Your urine is most concentrated when you first get up, so hCG levels (if present) will be easier to detect at that time. If that's the case, it's better to throw it away and get a new one. If you've been storing the test anywhere that gets moist or warm, like the bathroom, it may have deteriorated. Check the expiration date on the package, especially if you've had it for a while. How do I use a home pregnancy test?įor best results when using a home pregnancy test: For example, a pregnancy test that claims to be able to detect hCG at 20 mIU/ml should be more sensitive than one that claims to detect it at 50 mIU/ml. New products come out frequently, and manufacturers can make improvements at any time.īut some package inserts provide information about a test's sensitivity – that is, they report the lowest concentration of hCG in milli-International Units per milliliter (mIU/ml) of urine that the test can detect. It's not always easy to tell which tests are the most sensitive. The ability of a test to pick up small amounts of hCG in your urine depends on the sensitivity of the test. Detecting hCG in the urine of someone 6 months pregnant (when there's plenty of hCG) versus 6 days past ovulation (when there's a very small amount of hCG) are two very different tasks. What will differ between tests is their sensitivity. As long as a test isn't expired, it should be equally as accurate as another test.

The amount of hCG in your body then increases rapidly over the next few weeks, often doubling every two days or so. It first enters your bloodstream when the fertilized egg starts to implant in the lining of your uterus, as early as six days after fertilization. This hormone is produced by cells that will develop into the placenta. Talk to your pharmacist about which brand may be best for you.Home pregnancy tests tell if you're pregnant or not by detecting the presence of hCG in your urine. For that reason, some tests are better than others at detecting hCG early on. Some home pregnancy tests are more sensitive than others. This means home pregnancy tests can be accurate as soon as 1 day after a missed period for some women but not for others. In up to 10% of women, implantation does not occur until after the first day of a missed period. Your body makes hCG after implantation occurs. Plus, the fertilized egg can implant in a woman's uterus at different times. Each woman ovulates at a different time in her menstrual cycle. Also, testing your urine first thing in the morning can boost the accuracy. Most home pregnancy tests can accurately detect pregnancy after a missed period. The earlier you take the test, the harder it is for the test to detect the hCG. The amount of hCG or pregnancy hormone in your urine increases with time. Research suggests that waiting 10 minutes will give the most accurate result. Wait up to 10 minutes after taking the test to check the results window. Be sure to check the expiration date and follow the instructions. Most home pregnancy tests claim to be up to 99% accurate.
