In every cycle there are only a few days when a woman can conceive, so having sex on these days is very important if you are trying to get pregnant. The Clearblue® Easy Ovulation Test will help maximize your chances of conceiving naturally by identifying your 2 most fertile days each menstrual cycle. The ovulation tests measure changes in the level of a key fertility hormone - luteinizing hormone (LH) which is more accurate than calendar and temperature methods at identifying the most fertile days of the cycle1

    1. Before testing

    - Please always read the instructions on pack and in the leaflet carefully before use.

    - Start testing on Day 9 of your cycle.  To work out when Day 9 is count the day your period starts as Day 1 and continue counting through to Day 9.  This is the day you should start testing.

    - You can test at any time of the day, but you should test at the same time each day.

    - Try not to urinate for 4 hours before you do the test, and you should avoid excessive fluid intake before testing – You might find it easier to use the first urine of the day. 


    2. Get ready to test

    - When ready to begin testing, open the foil wrapper.  Remove the test stick and take off the cap.  

    - Hold the tip pointing downwards in your urine stream for 5 seconds only.

     - Or if you prefer, you can collect a sample of your urine in a clean, dry container and dip just the tip for 20 seconds.



    3. Wait for 3 minutes

    - Replace the cap, and keep the tip pointing downwards or lay the ovulation test stick flat. Your results can be read at any time between 3 and 10 minutes. 

    - Discard the test after 10 minutes.

    4. Read your results

    - Look at the result window and compare the surge line with the reference line. 

    - The surge line is next to the arrow and indicates the level of LH in your urine.

    - The line furthest away from the arrow is the reference line The reference line shows you’ve done the test correctly.  If this doesn’t appear in 10 minutes, test again with a new test.  



    - If there is no surge line or it is a lighter shade than the reference line then you have not begun your LH surge.  Continue with daily testing. 



    - If the surge line is similar to, or darker than the reference line then you have detected your LH surge.  You should ovulate within the next 24 to 36 hours.


    5. Once you have detected your surge

    -  Your 2 most fertile days begin once you detect your LH surge.  Have sex at any time during the next 48 hours to maximize your chances of becoming pregnant.

    - There is no need to continue testing this cycle.

    Frequently asked questions

    Can I collect a urine sample and test it later?

    Yes. If your urine sample has to be stored for more than one hour, it should be kept in the refrigerator (do not freeze) and then allowed to reach room temperature for about half an hour before doing the test.

    How accurate is the Clearblue® Easy Ovulation Test?

    The Clearblue® Easy Ovulation Test has been shown in extensive laboratory trials to be 99% accurate in detecting the LH surge prior to ovulation.

    Do I need to compare my daily readings?

    No. Each day’s reading is a straightforward ‘LH Surge/No LH surge’ answer.

    Do I need to use all 5 tests?

    No. You can stop testing when you detect your LH surge and save any remaining tests to use in your next cycle if necessary.

    I’ve done all 5 tests as instructed, but have not yet detected my surge. What should I do?

    Cycle length varies from woman to woman and cycle to cycle, and it is possible that you may need more than one pack to detect your LH surge. Data from a study conducted in the UK with 109 women showed that 47% would detect their LH surge using 5 test sticks. If you do not detect your LH surge using 5 test sticks you should continue testing with test sticks from a new pack. The same study showed that 91% of women would detect their LH surge using 10 test sticks.

    Some women do not ovulate each cycle. This is not unusual but we recommend you see your physician if you do not see your LH surge for 3 consecutive cycles.

    I have used a Clearblue® Easy Ovulation Test but no Reference Line has appeared. What should I do?

    This may be because too much or too little urine has been used, or the absorbent tip was not kept pointing downwards or the test stick was not laid flat after urine was applied. You should test again, using a new test. You may wish to collect a sample of your urine. It is important that you have not urinated for at least 4 hours before testing. Take care to follow the instructions.

    Can any medication or medical condition affect the result?

    • Always read the manufacturers’ instructions for any medication that you are taking before conducting a test.

    • Certain medical conditions and medications can adversely affect the performance of the test,  for example if you are actually pregnant, have recently been pregnant, have reached menopause or have polycystic ovarian syndrome you may get a misleading result. This may also be true if you are taking fertility drugs containing Luteinizing Hormone or human Chorionic Gonadotrophin (such as Pregnyl® and Profasi®)

    • Clomid®3 does not affect the tests.

    I’ve recently stopped using hormonal contraception (e.g. the pill). Will this affect the results?

    No, it will not affect your results.

    I’ve been using the Basal Body Temperature (BBT) method to find my best days to get pregnant. Can the Clearblue® Easy Ovulation Test take its place?

    Yes. In fact the BBT method can only tell if you have already ovulated - and this may be too late for you to make the most of your best days to get pregnant. The Clearblue® Easy Ovulation Test can tell you 24 - 36 hours in advance of when you should ovulate.

    I’ve used the Clearblue® Easy Ovulation Test and haven’t become pregnant. Can I be sure of getting pregnant?

    It can take normal healthy couples many months to achieve a pregnancy. We recommend you see your physician if you are under 35 years and haven’t become pregnant after trying for 12 months. If you are over 35 years you should see your physician after trying for 6 months, and if you are over 40 years see your physician straight away.
