Clearblue Advanced Digital Ovulation Test detects & tracks 2 key fertility hormones – luteinising hormone (LH) and estrogen (E3G): when a rise in estrogen is detected you have reached High Fertility, and when a surge in LH is detected you have reached Peak Fertility. Making love on High and Peak Fertility days maximises your chances of getting pregnant. Clearblue Advanced Digital Ovulation Test is over 99% accurate at detecting the LH surge. The clear digital display shows a Clearblue smiley face to identify your best days to get pregnant. Clearblue Advanced Digital Ovulation Tests are 2X MORE ACCURATE vs calendar methods* and unlike basal body temperature (BBT) charting, ovulation predictor kits detect the rise in luteinising hormone (LH) that rises prior to ovulation to accurately detect the day BEFORE, and day of ovulation. UNMISTAKABLY CLEAR DIGITAL RESULTS VS VISUAL OVULATION TEST STRIPS: the digital display shows within 5 minutes a clear smiley face when your LH surge has been detected, so you know your best days to try for a baby. Once your LH surge is detected have sex at any time during the following 48 hours to maximise your chances of getting pregnant. Research shows 73% of women did not find test strips easy to use*. Also, 1 in 4 women can misread a traditional ovulation line test (Johnson S., et aI. Exp Op Med Diag (2011) 5: 467-73). TYPICALLY IDENTIFIES 2X MORE FERTILE DAYS VS OVULATION TEST STRIPS: Clearblue Advanced Digital Ovulation test typically detects 4 OR MORE fertile days in each cycle, identifying both High and Peak Fertility days*. This means you have more opportunities to get pregnant - at least twice as many days as with any other ovulation test*. As sperm can survive in your body for up to 5 days, you can become pregnant by having intercourse during the days leading up to ovulation (on high and peak fertility days) to MAXIMISE YOUR CHANCES OF GETTING PREGNANT. Whether you have regular or irregular cycles, this product is great if you are trying for a baby. PERSONALISED PREDICTIONS: Clearblue Digital Ovulation Tests feature an Adaptive Algorithm that daily adjusts to your unique LH levels, designed to detect MORE LH surges and LOW LH surges even below 25 mIU/ml. And 2 out of 3 women have an LH surge under 25mIU/ml*. This kit takes the guesswork out of timing. EASY TO USE: all Clearblue ovulation tests come with a clear instruction for use leaflet in the box that make testing easy, even for first-time users. This kit is also easy to use when you are travelling (it works offline); it contains 1 digital holder and 20 test sticks. WHEN TO START OVULATION TESTING (IN MY CYCLE)? You need to know the length of your cycle to know which day you should start testing. Your cycle length is the total number of days from Day 1 (first day of full bleeding) up to and including the day before your next period starts. If your cycles vary, use the shortest cycle among the last 6. If you don’t know how long your cycle is, wait one cycle and note the length of this. WHEN TO TEST IN THE DAY? Test at any time of the day (morning urine not necessary), but at the same time each day. CAN I USE THIS OVULATION TEST KIT WITH AN APP? Yes. With our FREE comprehensive fertility tracking app designed for use with Clearblue Digital Ovulation Tests or Clearblue Advanced Digital Ovulation Tests, you can store your data, predict your periods, track your cycles, try for a baby - and share this information easily with your doctor or fertility specialist if needed. To find out if your phone is compatible and if the Clearblue Period & Cycle Tracker app is available in the country you live in, visit our Clearblue website. We respect your privacy: enjoy using the app without the need to provide your name, email, or phone number.

Please note test sticks are not available separately. Can any medical condition affect my result? You may get misleading results if you are pregnant, have recently been pregnant, have reached the menopause, have impaired liver or kidney function, have polycystic ovarian syndrome (PCOS). Can any medication impact my result? Always read the manufacturer’s instructions for any medication you are taking before testing. You may get misleading results if you are taking fertility drugs containing luteinising hormone (LH) or human Chorionic Gonadotrophin, or are taking antibiotic containing tetracyclines. Some fertility treatments such as clomiphene citrate may give misleading High Fertility results but Peak Fertility results should not be affected. If you have recently stopped using hormonal contraception your cycles may be irregular so you may wish to wait until you have had 2 cycles before testing. Checking with your doctor: as prenatal care is very important for a baby’s health, we recommend that you consult your doctor before you try to conceive. Check with your doctor if you are taking any medication or have any medical condition before planning a pregnancy. If you have a medically diagnosed fertility problem, ask your doctor if this test is suitable for you and if you do get unexpected results discuss them with your doctor. If you are under 35 years and haven’t become pregnant, we recommend you see your doctor after 12 months. If you’re over 35 years see your doctor if you haven’t become pregnant after 6 months, and straight away if you are over 40.

Review: Good accurate results from these tests! - These are a great way for you to detect and work out accurately when you are ovulating in your monthly cycle. It is intended to use them before you think you are ovulating and then throughout the time you are ovulating to allow the tests to detect two separate hormones: estrogen and LH. I found them easy to use and way more accurate than when testing and using other brands. They helped us to get pregnant before and I’m sure they will help us conceive again naturally this time around. They are pricey but I think they are worthwhile to have and use. Would recommend to all, friends and family! Review: Great product! - These tests are very useful for detecting your earlier fertile window but I do think cheapie LH strips are just as good for detecting peak. There is a lot of misunderstanding in the poorer reviews about how to use them. I want to start by start by saying that the low reviews referring to using their husband’s urine or dipping it in water and still having a flashing smiley are misunderstanding how these tests work. The first day you test is always negative, which is why it’s important to start before your fertile window. This measures a baseline from which it can detect an estrogen surge (flashing smiley) and an LH surge (static smiley). Once it has detected an estrogen surge and you have flashing smiley, it will display this UNTIL you have a LH surge and it changes to a static smiley. The static smiley will then stay on the screen for 48 hours because there is no need to test after this point. Because if this, once you have a flashing smiley, you can dip it in whatever you want and it will continue to flash a smiley. It will not measure any drop in estrogen because it’s not designed to do that. It is assuming that once it has detected your estrogen rise, that it will continue to do so until your LH surge. I think these tests are great for detecting your early fertile window, but in my case I wondered if it started flashing too soon. I got 5 days of flashing smiley before the 48 hours of static. If I’m not pregnant this month we will maybe wait until a couple of days into the flashing smiley before having sex as we tired ourselves out! Perhaps alternate days during flashing smiley would suffice next time. If you have very regular periods, I wouldn’t spend your money on these. If your periods are a little irregular (mine are 28-32 days) they are very useful for pinning down your fertile window for that month. I will definitely buy these again. EDIT - I just wanted to add that after 16 cycles I am pregnant this cycle! I’ve had an early loss before so it may not work out but I’ll be ordering these again if it doesn’t. ## Features - NO OVULATION TEST BRAND IS MORE ACCURATE*!

When a rise in estrogen is detected you have reached High Fertility, and when a surge in LH is detected you have reached Peak Fertility. **Q: What if you don’t see High Fertility?** A: If you don’t see any High Fertility days or fewer than expected, it may be that in this cycle your estrogen level is not high enough to be detected. Alternatively it may be your hormone changes occur close together or you started testing too late. **Q: What if you don’t see Peak Fertility in a cycle?** A: It may be that in this cycle your LH surge was too low to be detected or you may have missed a test around your LH surge. It is also possible that you have not ovulated this cycle. **Q: Started testing on the right day and seen 9 or more High Fertility days?** A: You may wish to stop testing this cycle. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good accurate results from these tests! *by A***H on 18 June 2026* These are a great way for you to detect and work out accurately when you are ovulating in your monthly cycle.

I think the price is a little higher than other products on the market but they are well worth the extra expense for ease and reliability. Added bonus that it comes with a pregnancy test too.
