May prevent false positive results in a very small number of women.
A very small number of non-pregnant peri and postmenopausal women may have very low levels of hCG in their urine due to changing hormone levels associated with the menopause transition. To find out more, read on below.
In the USA and across much of the developed world, women are waiting longer to start a family. Data from the CDC shows birth rates have increased for women in their early 40s since the 1980s.* This increase in women seeking pregnancy later means that more women could be in peri or postmenopause when taking a pregnancy test.
Though hCG (human chorionic gonadotropin) is known as ‘the pregnancy hormone’ a very small number of non-pregnant peri and postmenopausal women can have very low levels of hCG in their urine due to changing hormone levels associated with the menopause transition. Notably the rise in FSH (follicle stimulating hormone) which is associated with approaching menopause can result in tiny amounts of hCG being produced in a very small number of women. In a Clearblue clinical study 3% of perimenopause women (40-50y) had a urine hCG concentration >5mIU/ml.
Figure 1: Mean, 10th and 90th centiles of urinary FSH and hCG concentrations in pre-, peri- and post-menopausal women (FSH and hCG in mIU/ml). 397 urine samples (97 pre- (age 18-40), 150 peri- (age 41 to 55) and 150 post-menopausal (age 56-65)) were collected from volunteers who participated in a urine collection study conducted by Clearblue®.
This small number of non-pregnant peri and postmenopausal women who may have very low levels of hCG in their urine could carry the risk of returning a false positive result should they use a high sensitivity test for hCG, such as one that can be used very early.
That’s why Clearblue® Early Detection Pregnancy Test includes DualSenseTM Technology, to offer women the clinical benefits of early testing, and for the very small number of non-pregnant women who may have low levels of hCG in their urine, the potential for a reduced risk of false positives by detecting hCG and recognising the presence or absence of high levels of FSH. If hCG is raised in the presence of high levels of FSH, the hCG is unlikely to be due to pregnancy and thanks to DualSenseTM Technology the test should deliver a negative result.

How to use Clearblue® Early Detection Pregnancy Test
1. Before you begin
Always read the package insert carefully before testing. If you’re testing before you expect your period, use the first urine of the day, as any pregnancy hormone will be more concentrated. Otherwise you can test any time of the day, as hormone levels will be higher if you are pregnant. Avoid drinking lots of liquid including water, before using your Early Detection Pregnancy Test to make sure you don’t dilute any hormone in your sample.
When ready to test, remove the test stick from the foil wrapper, take off the blue cap and use the test straight away.
2. Take the test
Hold the test with the absorbent tip pointing downward, and place just the absorbent tip in either your urine stream for 5 seconds, or in a urine sample collected in a clean, dry container for 20 seconds.
IMPORTANT
Avoid getting the plastic housing wet during sampling.
Replace the cap and lay the test stick on a flat surface.
IMPORTANT
Throughout testing never hold the test stick with the absorbent tip pointing upwards.
3. Wait for your result
Red lines will start to develop. Wait 5 minutes before reading your result.
4. Read your result
If you see two lines, you are pregnant. It does not matter how faint or dark the lines are.
If you see one line, you are not pregnant A red line must be present in the control window for your result to be valid.
IMPORTANT
Read your result within 10 minutes of testing. Do not read results after 10 minutes.
FAQs
How does Clearblue® Early Detection work?
It detects the pregnancy hormone hCG (human Chorionic Gonadotropin) in urine.
How early can I test?
You can test 6 days before your missed period, which is 5 days before you expect your period.1
However, as hormone levels vary from woman to woman, and in early pregnancy can be very low, you may be pregnant but still get a negative result.
How accurate is Clearblue® Early Detection?
It is more than 99% accurate in detecting whether or not you are pregnant, when used from the day you expect your period.2
My test says I’m pregnant. What should I do?
See your doctor as soon as possible who may confirm your pregnancy, after all clinical and laboratory findings have been evaluated.
My test says I’m not pregnant. What should I do?
You may not be pregnant, or the level of pregnancy hormone may not yet be high enough to be detected. If you tested before your expected period, test again when your period is due. If this test gives you a ‘Not Pregnant’ result and you still think you might be pregnant, see your doctor.
Can any medication or medical conditions affect the result?
Always read the manufacturer’s instructions for any medication you are taking before testing. Medications containing hCG or FSH and other hormone therapies may affect the result.
The test should NOT be affected by hormone therapies containing Clomiphene citrate, common painkillers, alcohol, antibiotics, or the contraceptive pill.
If you get unexpected results you should discuss them with your doctor.
How does DualSense™ Technology work?
Though known as the ‘pregnancy hormone’, a very small number of non-pregnant women may have low levels of hCG in their urine. If these women use a very sensitive pregnancy test, they have a very small risk of a false positive result. This test may prevent false positives in some of these women.
