It’s recommended that you wait until your period is due to arrive to take a pregnancy test because you have the highest rate of receiving an accurate result. If you test earlier, you do risk receiving a false negative result. Let’s take a look at the current most sensitive pregnancy tests on the market. How Do Home Pregnancy Tests Work?

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. How accurate are home pregnancy tests? These test strips have a sensitivity of 25 mIU/ml, which isn’t nearly as sensitive as First Response. If you wait until you are 12-14 DPO, using these tests is no problem, and there are a lot of other brand tests with a sensitivity that is not this low. Some pregnancy tests have a low threshold, but others might not indicate a positive result until your levels are over 75 mIU/ml. Those tests wouldn’t be ideal for early detection, but they should work for taking a test when you miss your period. How Early Can I Take a Pregnancy Test? Pregnancy tests detect the pregnancy hormone, human chorionic gonadotropin hormone (hCG), in your urine. This hormone starts to be produced around six days after fertilisation. There are 2 ways you can use your First Response Pregnancy Test, and each will give accurate results, so the way you want to test is entirely up to you. Begin by removing the pregnancy test from its wrapper and removing the protective cap from the absorbent end of the test, then take your test in one of the following ways:Typically, you never want to test before eight days post ovulation. Your body needs time to send the fertilized egg down your fallopian tubes, and the egg needs to implant into your uterine walls and start to develop the HCG hormone that pregnancy tests detect. Aside from being the most sensitive pregnancy test, First Response displays the results in three minutes, on average, and that’s faster than other brands. The curved handle makes the test screen easier to read, and it seems to help avoid user error. If you get too much urine on the pregnancy test, you might void the test, but the curved handle reduces that chance! 2. Clearblue Rapid Detection If you’re keen to test early, but don’t want to leave yourself squinting into the sunlight or editing photos of your pregnancy tests to see if that line is solely in your imagination, the Clearblue Digital Early Detection Pregnancy test can make the testing experience a whole lot simpler. Unlike dye-based tests that require looking out for a line or cross in the results window, these tests use digital technology instead. Home pregnancy tests work by detecting the hCG hormone in your urine, however, in some circumstances, such as when you are having fertility treatment or have medical conditions, you may be asked to head for a blood test with your doctor.

This test is 99% accurate at detecting pregnancy from the day of your expected period. Once again, this test isn’t as sensitive as the First Response, and it can detect HCG at levels of 25 mIU/ml. That’s not low, but we know it’s more sensitive than other tests.Testing before eight DPO increases the likelihood that you’ll receive a false negative because implantation typically occurs between 8-9 DPO. Asthma Our Asthma service is ideal in emergencies when you are unable to visit your own doctor and need your inhaler urgently. It is designed for emergencies and not regular use and requires you to have add a recent asthma review. It is recommended you take a pregnancy test on the first day after your period would have been due.

Are cheap pregnancy tests accurate? Acid Reflux Heartburn is a burning feeling in the chest caused by stomach acid travelling up towards the throat (acid reflux). If it keeps happening, it’s called gastro-oesophageal reflux disease (GORD).

The HCG sensitivity is nowhere close to FRER. It’s listed as 22 mIU/ml, and that could take two days to reach that point. Knowing two days earlier does matter to a lot of women. 3. Clinical Guard HCG Pregnancy Test Strips When you take your First Response Early Detection pregnancy test from the first day of your expected period, your results will be over 99% accurate. Although you can use this test up to 5 days before your expected period, your test may be less effective the earlier you test. This is why many women who test early choose to take a second test on the day of their expected period, to confirm their results with more accuracy. Laboratory testing of these First Response tests saw the following results:A lot of women complain that taking blue dye tests can give wrong results, but Clearblue designed an excellent test with a big sponge tip that makes taking these tests easier.

Generally speaking, as the levels of the pregnancy hCG hormone rise every two or three days during pregnancy, a pregnancy test will be more accurate the later you leave it after having unprotected sex.All home pregnancy tests work the same way - by measuring the hCG levels in your urine- but when it comes to dye-based tests, which are the ones which give line results, there is some debate as to whether pink dye based tests or blue dye tests are better. Whilst this is a frequent topic of discussion on the Mumsnet Conception boards, the general consensus is usually that pink dye tests - such as First Response Early Result tests - are more trustworthy than blue dye tests, which can be more likely to show evaporation lines and even false positives. What are the best pregnancy tests UK? Ease of use - Most pregnancy tests involve measuring the level of hormone present in your urine, but some are easier to use than others. Most home pregnancy tests tend to have a plastic casing around them, but you can also buy cheaper pregnancy strips, such as One Step, which have no casing but can be just as effective at detecting hCG. When testing, you would need to dip an uncased pregnancy strip into a pot of urine rather than attempt to wee on it. If you’re not sure when your next period is due, aim to test at least 21 days after you last had unprotected sex. What other kinds of pregnancy tests are there? Moms rave about these tests.
