ClearBlue Ovulation Test Advanced Digital
Read this leaflet carefully before testing
5 important points you need to read
- Peak Fertility is displayed constantly for 48 hours after it first appears. The holder will not be able to read another test whilst this is displayed.
- Every woman’s cycles are unique and hormone patterns differ so the number of fertile days you see is personal to you. In a study of 87 women, this is what we saw:
Number of High Fertility days before Peak Fertility % of women 0-4 66% 5-9 25% 10+ 1% No Peak Fertility after High Fertility 8% TOTAL 100% - If you started testing on the right day and you see more than 9 High Fertility days you may wish to stop testing as it’s unlikely that you will see Peak Fertility this cycle. See Q4.
- Only test once a day until you see High Fertility. For reliable results, you must use the urine after your longest sleep. When you see High Fertility you can test more often. Drink normally and it’s important not to urinate for 4 hours before testing again.
- If you remove the batteries from the holder you will not be able to use it again.
How to Do a Test
- Work out when to start testing
- Use the table below to work out when to start testing.
- The day your period starts (first day of full bleeding) is Day 1. Your cycle length is the total number of days from Day 1 up to and including the day before your next period starts.
- If your cycle length varies use the shortest cycle over the last 6 to work out when to start testing.
- If you don’t know how long your cycle is, wait at least one cycle and note the length of it so you know when to start testing.
- It’s important to start testing on the day shown in the table, for example, if your cycle lasts 27 days start testing on day 7.
Always test using the first urine after your longest sleep.
- Insert the test stick into the holder
- When you are ready to test, take a test stick out of the foil and take off the cap.

- Put the test stick into the holder making sure the purple arrows line up as shown.

- The first time you use the test the new cycle symbols will flash briefly.

- The ‘test ready’ symbol will then appear. Do the test straight away. If this symbol does not appear or the screen goes blank eject the test stick and put it back into the holder.

- When you are ready to test, take a test stick out of the foil and take off the cap.
- Do the test
- Either…put just the absorbent tip pointing downwards into your urine stream for 3 seconds. Take care not to get the holder wet.

Or…
collect a sample of your urine in a clean, dry container and put just the absorbent tip into the sample for 15 seconds.
- Replace the cap, wipe off any excess urine. Keep the absorbent tip pointing down or lying flat.
- Either…put just the absorbent tip pointing downwards into your urine stream for 3 seconds. Take care not to get the holder wet.

Your LH surge has been detected – today and tomorrow are your most fertile days. Once the first day of Peak Fertility is displayed don’t try to test again this cycle.
How long it will be displayed Low and High Fertility results are displayed for 8 minutes. If you miss seeing your result, eject the test stick and it will re-appear for another 2 minutes. Peak fertility is displayed constantly for 48 hours. If no result is displayed see ‘Other symbols and what they mean’.

Further information
- This test works differently to other ovulation tests which detect one hormone. This test detects 2 key fertility hormones – estrogen and luteinising hormone (LH). It’s important for the test to establish ‘baseline’ levels of these hormones so start testing as advised and keep testing with the same holder until you see Peak Fertility.
- If there’s no significant rise above the baseline level of hormones Low Fertility is displayed. You may see a number of Low Fertility days before you see High or Peak Fertility.
- Estrogen rises in the days before the LH surge and prepares your body for ovulation. When an estrogen rise is detected High Fertility is displayed each day until Peak Fertility is detected.
- High Fertility is indicated as a flashing smiley face.
- If an estrogen rise isn’t detected, or the estrogen rise and LH surge are close together, you may not see High Fertility.
- An LH surge happens about 24-36 hours before an egg is released from an ovary – ‘ovulation’. When your LH surge is detected Peak Fertility is displayed and is generally displayed after Low and High Fertility.
- Peak Fertility is displayed as a static smiley face (it does not flash) and stays on the display constantly for
48 hours. If your LH surge is detected on the first day of testing Peak Fertility will be displayed. - You may not see Low, High and Peak Fertility days every cycle. This is not unusual. Refer to Questions and Answers for more information.
- Make love on High and Peak Fertility days to maximize your chances of getting pregnant.
Questions and Answers
- What happens if I don’t use the first urine after my longest sleep?
You may get unexpected High Fertility results.
Test as soon as you can but drink normally. - How accurate is Clearblue Advanced Digital?
A laboratory study has shown the test to be over 99% accurate in detecting the LH surge (Peak Fertility).* - I’ve not seen any High Fertility days. Why is this?
It may be that the estrogen level is not high enough to be detected, or your hormone changes occur close together, or you started testing too late. You may still see Peak Fertility and you can rely on these results. - I’ve not seen any Peak Fertility days. Why is this?
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. - Can any medication or medical conditions affect the result?
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 impaired liver or kidney function, have the polycystic ovarian syndrome, are taking fertility drugs containing luteinizing hormone or human Chorionic Gonadotrophin, or are taking antibiotics containing tetracyclines.
Some fertility treatments such as clomiphene citrate may give misleading High Fertility results. Peak Fertility results should be unaffected.
If you do get unexpected results you should discuss them with your doctor.
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 may wish to wait until you have had 2 cycles before testing.
Please 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 you should ask your doctor if Clearblue Advanced Digital is suitable for you. - How do I recycle the batteries and dispose of the holder?
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. Caution: Do not take apart, recharge, or dispose of the batteries in fire. Do not swallow. Keep away from children. Dispose of the rest of the holder according to the appropriate recycling scheme for electrical equipment. Do not dispose of electrical equipment in fire. - Are test sticks available separately?
No. 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.
I’ve used Clearblue Advanced Digital for several months and haven’t become pregnant. Why is this?It can take normal healthy couples many months to achieve a pregnancy. We recommend you see your doctor 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 doctor after trying for 6 months, and if you are over 40 years see your doctor straight away.
