May prevent false positive results in a very small number of non-pregnant women who may have low levels of hCG in their urine.
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.
hCG in perimenopause
Across much of the developed world, women are waiting longer to start a family. * In the EU the total live births to mothers over 40 in a year has more than doubled between 2001 and 2019. 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 is accompanied by 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 Ultra Early ADVANCED Pregnancy Test includes DualSenseTechnology, 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 DualSense Technology the test should deliver a negative result.

Leaflet
How to use Clearblue® Ultra Early ADVANCED Pregnancy Test
1. Before you begin
Always read the instruction leaflet 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 Ultra Early ADVANCED 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 full 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.
