Clearblue Trying For a Baby Advanced Digital Ovulation Test, Kit of Test 20Clearblue Advanced Digital Ovulation Test is the first and ONLY test that typically identifies 4 or more fertile days each cycle. It tracks 2 key fertility hormones to identify your High AND Peak fertility days, so you can plan and have more opportunities to get pregnant. Clearblue Advanced Digital Ovulation Test works differently to other ovulation tests as it is designed to detect 2 hormones, estrogen and LH. TEST ONCE A DAY: The only test once a day until you see High Fertility. For reliable High Fertility results, you must use the urine from after your longest sleep. When you have seen High Fertility you can test more often, but avoid excess fluid intake before testingTRACK FERTILITY HORMONE: It's the only ovulation test to accurately track not only luteinising hormone but also estrogen to identify your wider fertility window. You cannot do another test while Peak Fertility is shown, as the holder will not be able to read it.SMART TECHNOLOGY: With its unique algorithm, the test adapts to your hormone profile, so you are less likely to miss your fertile days. The clear digital display gives you a Clearblue smiley face when it identifies your best days to get pregnant.RE-USABLE READER: If you have ovulation test sticks left after detecting your first LH surge then you can use them with the same test holder to identify your fertile day's next cycle if you're not already pregnant.Safety Warning: Please read the enclosed leaflet before use.
