How to use your Clearblue Advanced Digital Ovulation Test
In every cycle, there is only a short window of time when baby making is possible. The good news is, your new Clearblue Advanced Digital Ovulation Test Kit helps to track your high and peak fertility days so that you can make the most of that window.

Frequently Asked Questions
You should test as soon as you can after your longest sleep. If you do not use the first urine after your longest sleep, you may see unexpected High Fertility results.
It’s important to know your cycle length to work out what day you should begin testing. Your cycle length is the number of days from when your period starts (day 1) to the day before your next period starts. The instructions that come with your kit provide a table for working out what day to begin testing depending on your cycle length.
If your cycle length is irregular, use the shortest cycle over the last 6 cycles to work out when to start testing.
It is important to only test once a day for your High Fertility results to be reliable. After your first day of High Fertility has been displayed, and the tests start looking for your LH surge, you can test more frequently if you would like to.
Yes, the test reads your individual hormone levels and the level of oestrogen will be checked on the first day you test in each cycle. High Fertility cannot be displayed on the first day you test as the test needs to determine your baseline level. Further tests use this baseline level to detect a significant rise in oestrogen, where it will display High Fertility. The test will then continue to display High Fertility until it detects the LH surge and Peak Fertility is displayed.
There are enough test sticks in this pack for most women with regular cycles to detect their High and Peak Fertility. If your cycle length is long or irregular, you may need to do more tests. Continue to use the same holder with test sticks from a new pack. Some women may still see Peak Fertility even if they have not seen High Fertility. This may be because the rise in oestrogen levels is not high enough to be detected, or you started testing too late.
Your LH surge may be too low to be detected, or you may not have ovulated this cycle. This is not unusual, but we recommend you see your doctor if you do not see Peak Fertility for 3 consecutive cycles. If you miss a test around your LH surge, you may not see Peak Fertility, so remember to test as advised and use the same holder throughout your cycle.
When the test detects a rise in oestrogen, it displays High Fertility (flashing smiley face) and will continue to display this until your LH surge is detected. There are a couple of reasons why you may see High Fertility displayed for a long time.
- If you started testing too early or too late in your cycle (after the LH surge has occurred).
- Occasionally, some women have an LH surge that is too low to detect, or they do not ovulate during a cycle so they may see a lot of High Fertility days but no Peak Fertility. This is not unusual.
If you started testing on the correct day for your usual cycle length and you see 9 or more days of High Fertility, it is unlikely you will see Peak Fertility in this cycle. You may wish to stop testing for this cycle and save any remaining tests for the next cycle. If you do not see Peak Fertility for 3 consecutive cycles, we recommend you discuss this with your doctor.
When your LH surge is first detected, the test will display a static smiley face (Peak Fertility) that will remain there for 48 hours, indicating your 2 most fertile days. You cannot do another test while peak fertility is displayed. Instead, you can save your remaining test sticks for your next cycle if needed.
Always read the manufacturer’s instructions for any medication that you are taking before testing. Certain medical conditions and medications can give misleading results. For example, if you are pregnant or have recently been pregnant, have reached menopause, have PCOS, or have impaired liver or kidney function. If you have recently been pregnant, you should wait until you have had 2 cycles before testing. If you have recently stopped using hormonal contraception, your cycles may be irregular, so you should wait until you have had 2 cycles before testing. Taking fertility drugs containing LH or human chorionic gonadotrophin, or taking antibiotics containing tetracyclines can also cause misleading results. Some fertility treatments such as ovulation induction medication may give inaccurate High Fertility results. Please check with your doctor if you are taking any medication or have any medical condition before planning a pregnancy.
A laboratory study has shown the test to be over 99% accurate in detecting the LH surge (Peak Fertility).
No. If you have used all the test sticks in the pack, you will need to buy a new pack containing a new holder and test sticks. Make sure to use the same holder throughout your cycle, just with the new test sticks. If you have any test sticks left at the end of testing, you can use these and the holder for your next cycle if needed.
Ideally, you would use one holder per cycle. However, if you have any tests sticks left over from the previous cycle, you can use these with the same holder for your next cycle if needed. For the cycle after that, use a new holder from the new test kit.
The reason for this is that if you were to use the same holder repeatedly, it may run out of battery half way through a cycle. This would mean you would lose all the information from this cycle and have to wait until your next cycle to test again.
If you remove the batteries from the holder, you will not be able to use it again. When you have finished using the holder, separate the upper and lower halves starting at the end nearest the display. Remove the batteries from under the central metal cover and dispose of them according to the appropriate recycling scheme.
There are no products available that can guarantee success in achieving pregnancy. The Clearblue Advanced Digital Ovulation Test kit typically identifies 4 or more of your most fertile days – the days leading up to and including ovulation. Having sex on these days can help to maximise the chance of you getting pregnant, although it is recommended that you should have sex every 2-3 days instead of everyday.
1. Test sticks are not sold separately. If you have used all the test sticks in the pack, you will need to buy a new pack containing a holder and test sticks. Use the same holder throughout your cycle with new test sticks. If you have any test sticks left at the end of testing, you can use these and the holder for your next cycle if needed.
2. Make sure to check the ‘use by’ date on your test kit. Using the test after this date may cause misleading and inaccurate results.
For self-testing at home. For in vitro diagnostic use only. Not for internal use. Do not reuse test sticks. Keep out of reach of children. Store between 2° – 30°C. Bring to room temperature for 30 minutes if refrigerated. Do not use if the foil wrapper containing the test stick is damaged. Do not use a test stick after the ‘use by’ date. Only use test sticks for Clearblue Advanced Digital Ovulation Test with the holder. Not for contraceptive use.
Results must be read on the display and not by any lines you might see on the test stick. Do not take test apart, recharge, or dispose of the batteries in a fire. Do not swallow batteries. Dispose of the rest of the holder according to the appropriate recycling scheme for electrical equipment. Do not dispose of electrical equipment in a fire.
