Q1. How accurate is Clearblue Digital Pregnancy Test
Clearblue Digital Pregnancy Test is more than 99% accurate in laboratory tests, when used from the day you expect your period to start. If you are testing earlier than the day of your expected period, the accuracy of Clearblue Digital will be lower. In lab testing, 99% of 'Pregnant' results were detected 1 day before the expected period, 98% at 2 days before, 95% at 3 days before, and 75% at 4 days before.
Q2. When can I test with Clearblue Digital Pregnancy Test with Smart Countdown
The pregnancy hormone hCG increases rapidly in early pregnancy and Clearblue Digital can be used to test 5 days before your missed period (which is 4 days before you expect your period). If testing before your expected period, you must use the first urine of the day; otherwise you can test at any time of the day.
Q3. Can any medication or medical conditions affect the result
Always read manufacturer's instructions for any medication you are taking before testing. Fertility medications containing hCG (such as Pregnyl and Profasi) can give misleading results (these fertility medications are usually given by injection) and testing too soon after administration may give a false 'Pregnant' result.
Other fertility therapies (such as Clomid), painkillers and hormonal contraceptives (e.g., birth control pills) are unlikely to affect the result. If you have recently stopped using hormonal contraception or are using fertility therapies like Clomid, yo r periods may be irregular, leading you to test too soon. If you have recently been pregnant (even if not carried to full term), you may get a false 'Pregnant' result. If you are in or approaching menopause, you may obtain a false positive result even though you are not pregnant. In a study of women tested with different lots of Clearblue, an average of 0.3% of results were positive, with a range from 0% to 1% for different lots. All false positive results were from women aged over 50 years. Ectopic pregnancy and ovarian cysts can give misleading results. If you have a 'Pregnant' result, it is possible that you may later find that you are not pregnant due to a natural loss of the pregnancy, which can occur in the early stages. If you get unexpected results, you should discuss them with your doctor.
Q4. The Smart Countdown went much faster than I expected, what does this mean
Some results can be displayed in as little as 1 minute. In such cases the Smart Countdown segments will appear more rapidly. A 'Pregnant' result is displayed on the screen for up to 6 months, for your use when you're ready to share the news. A 'Not Pregnant' result lasts for approximately 24 hours.
