If you test too early in your cycle with a home pregnancy test, you could receive a false negative result, especially if your body is only producing a scant amount of hCG and the test is not sensitive enough to pick it up. Keep in mind, though, that the closer you are to the date of your expected period, the more accurate a home pregnancy test will be. It’s easy to hold, the absorbent pad is wide (as with other Clearblue tests), and its claimed accuracy is fairly high: 95% three days before an expected period and 75% a day earlier.

Whether it’s finding great products or discovering helpful advice, we’ll help you get it right (the first time). A test that claims to be 99% accurate on the day of an expected period may claim just 50% accuracy a few days earlier.We chose 26 tests to try based on their popularity and availability, as well as their ratings at online retailers. Each test’s design is slightly different, but it generally goes like this: In the first area of the paper the urine hits, dyed antibodies cling to the beta region of hCG, and together, the two molecules flow forward to a second area, where antibodies that cling to hCG’s alpha region are stuck to the paper. You can use the EasyRead app to scan the test lines if you would rather see “pregnant” or “not pregnant. Some tests detect several of these variants, but it’s not clear whether that makes them more sensitive.

If you take it too soon, the hCG levels might not be high enough for the test to detect, leading you to believe you’re not pregnant. If no lines appear anywhere in the result window or if only the test line appears, the test has not worked properly and is invalid. Similar to First Response Early Result, Clearblue Early Detection can detect pregnancy five days before an expected period 71% of the time (that goes up to 94% four days before, 98% three and two days before, and 99% a day before an expected period).I can see the lines hope it's good news for us both iv done a clearblue about 10 mins ago but that came back negative but it is still early days so hopefully a few more days and I will know for deffo. The cassette has the same kind of strip inside, but there’s no plastic layer covering the test zone.

After three minutes, the display window will reveal one or two lines: One indicates a negative result, and two lines a positive result. You can do this midstream while going to the bathroom or collect a urine sample in a cup and dip the strip.The Smart Countdown features a progress indicator that flashes or counts down in the digital display window until you see the words “pregnant” or “not pregnant.
