Clearblue offers a range of home pregnancy tests, all of which detect the clinically proven urinary pregnancy hormone – human Chorionic Gonadotrophin (hCG) to provide accurate and trusted results in early pregnancy testing.

How hCG is used to detect pregnancy

The hormone hCG is produced in the earliest stages of pregnancy. During early pregnancy it plays a role in survival of the corpus luteum 1 and has a significant role in the implantation of the blastocyst and protection of the embryo against immune attack at the foetal/maternal boundary. The pregnancy hormone hCG is initially produced by the embryo and therefore acts as a marker for its presence. 2

HCG levels rise rapidly and predictably in the earliest days of pregnancy 3 and hCG can be detected in urine 9-10 days following estimated day of conception when using the most sensitive laboratory assays. 4 The levels of hCG in early pregnancy have also been found to be highly similar between women. 4 This makes hCG an ideal urinary marker for quickly and accurately assessing whether a woman is pregnant or not.

Clearblue Pregnancy Tests can be used Up to 6 days before the missed period

Published literature shows that pregnancy hCG levels reach at least 50 milli-International Units per milliliter (mIU/ml) on the day a pregnant woman’s period is due. 5-7 If a Clearblue Pregnancy Test is used from the day the period is due, it is more than 99% accurate in detecting pregnancy. 8 The high sensitivity of Clearblue Pregnancy Tests means that pregnancy can be detected up to 6 days before the missed period for women who wish to test early. The graph below shows a typical rise in urinary level of hCG from the first detection of pregnancy.

Reference ranges for urinary intact hCG for each day of pregnancy

*From calculated day of ovulation (LH surge +1 day)

Median, 10th and 90th centiles shown. Data from 109 UK volunteers 7

Not all pregnant women who test before the day their period is due will obtain a “Pregnant” result. This is because urinary hCG levels may not yet be above the threshold for the test.

Clearblue Pregnancy Tests are rigorously tested using early pregnancy urine samples from women whose luteinising hormone (LH) surge day is known and from which the day the period is due can be reliably estimated. 7 Using these samples it is possible to assess the proportion of pregnant women expected to have sufficient hCG levels in their urine sample to generate a “Pregnant” result, on each day with respect to the day of expected period. If women choose to test early with the Clearblue Pregnancy Test, the likelihood of detecting pregnancy before the day the period is due is clearly displayed on the product packaging. Any woman who tests and gets a ‘Not Pregnant’ result, but still suspects pregnancy, should test again the day the period is due if testing was done early, or 3 days later if the period is overdue.

Clearblue pregnancy tests are over 99% accurate from the day of the expected period

At Clearblue we believe that consumers need a result they can be confident in and act on, and therefore we provide pregnancy test products that deliver over 99% accuracy from the day of the expected period. 8

How hCG is used to estimate the time since conception

In order to demonstrate how hCG levels relate to the timing of conception it is important to conduct studies in which the day of conception has been accurately defined. Conception time can be estimated if the LH surge day is known in the cycle in which a woman became pregnant. LH surge is well validated as a marker of impending ovulation, 9-11 and ultrasound studies of follicular rupture have confirmed that the LH surge detected in urine occurs approximately 24-36 hours before ovulation. 12 As the egg survives for only around 0.7 of a day, 13 and the fertile period ends on the day of ovulation, 14 conception occurs shortly after ovulation. Therefore detection of the LH surge can be used to estimate the day of conception. Collection of urine samples from complete menstrual cycles in which the volunteer became pregnant and the LH surge is known can demonstrate the utility of hCG in providing an estimate of time since conception.

Following implantation, hCG levels rise exponentially and predictably in blood and urine so hCG has been used to estimate gestational age. 15,16 Rigorous trials have shown that there is a consistent pattern to urinary hCG levels in the first few weeks following conception 17 such that thresholds for the urinary hCG hormone can be assigned in order to determine time since conception in categories: 1-2, 2-3 and 3+ weeks since conception. These thresholds are employed by the Clearblue Digital Pregnancy Test with Weeks Indicator, so that the test provides not only a ‘Pregnant’/’Not Pregnant’ result, but also an estimate of the time since conception in these week bands.

Furthermore, pregnancy duration estimates using the Clearblue Digital Pregnancy Test with Weeks Indicator result are 97% in agreement with standard of care ultrasound results when ultrasound precision is taken into account. 18,19

Explaining ovulation awareness-based family planning methods

These easily taught birth control methods may be just what some patients are looking for. Nonhormonal approaches like the Standard Days and the TwoDay Methods hinge on identifying a woman’s fertile window: the days during her cycle when pregnancy is likely.

[The Billings Ovulation Method focuses on the cervical secretions produced in response to rising levels of estrogen during the late follicular phase of the menstrual cycle. 7 ] Women who use this method (developed in the 1960s by Drs. John and Evelyn Billings) are advised to observe their secretions many times daily throughout their cycle, to assess their quantity and quality (i. e., appearance, viscosity, and texture), to record their observations on a chart, and to avoid unprotected intercourse on all fertile days that the method has identified. They are taught to recognize the pattern of cervical secretions usually seen in a typical menstrual cycle—absence of secretions right after menses; scanty, sticky secretions for the next few days; abundant and wet secretions immediately before, during, and after ovulation; then absence of secretions again until after the next menses. Techniques for observing these secretions include noting their presence on toilet paper or underwear and simply being aware of a feeling of wetness at the vulva. Women using the Ovulation Method avoid unprotected intercourse during menses, on preovulatory days following days with intercourse, and on all days with secretions until the fourth day after the “peak” secretions day (i. e., the last day with watery, viscous secretions). Additional information about the Ovulation Method, including guidance for offering it to patients, is available from several sources, including http:// http://www. woomb. org/.

[The Symptothermal Method involves daily observation of cervical secretions as well as taking basal body temperature (BBT) readings. 8 ] Under the influence of progesterone, BBT rises at least 0.4�F around the time of ovulation and remains elevated until the end of the cycle. Women using the Symptothermal Method are told to observe their cervical secretions and BBT daily, record them on a chart, and apply the rules governing method use to avoid pregnancy. They’re also advised to identify when they’ve had 3 days of higher temperatures following 6 days with lower temperatures as confirmation that they have in fact ovulated. Further information is available at http://www. fertilityuk. org/.

Standard Days Method

The SDM, like other FAB methods, is based on the physiology of the menstrual cycle and the functional life span of the sperm and the ovum. 9 This method is appropriate for women whose menstrual cycles are usually between 26 and 32 days long (roughly 78% of cycles are within this range). 9 In developing the SDM, researchers considered two sets of probabilities: the probability of pregnancy vis-�-vis ovulation, and the probability of the timing of ovulation vis-�-vis the midpoint of the cycle.

How to scientifically predict ovulation

Many people have to know

In general, normal women of childbearing age ovarian monthly discharge of an egg, if not fertilized, the eggs in 12 to 24 hours after ovulation will be degraded, and the sperm in the female reproductive tract generally live for 3 to 5 days, so in 3

5 days before ovulation ovulation within 1 days after intercourse is easy pregnancy.

Determination of urinary LH

At present, the market has a strip of this test of urine LH (or predict ovulation test) for sale.

LH urine test strip and pregnancy test strip like.

The advantages and disadvantages

This is a kind of the existing prediction methods of ovulation accurately, is relatively simple, the only drawback may be expensive.

Schedule estimation method is generally used for women with regular menstrual cycles, their ovulation usually occurs within 14 days before the next menstruation.

35 days are normal).

A: the female menstrual cycle is stable

According to the days of the menstrual cycle has been recorded (record time, correct the higher) calculated the average days of their menstrual cycle, minus 14 days, the number is from the first day of menstruation is the assumed date of ovulation.

B: the menstrual cycle is not stable, but the shortest period and the longest period of difference is not great

Of course, if your menstruation is the shortest and longest menstrual cycle is not very large, can also be through the formula to calculate the fertile period or safety period:

The last day of the shortest cycle days before -19= safe period

The last day of the longest period of pregnancy -10= days

Such as: in the past, the shortest period recorded for 26 days, the longest period of 32 days, should be 26-19=7 days, 7 days before the period of safety period, eighth days into the easy pregnancy; 32-10=22 days, twenty-second day period is the last day of easy pregnancy.

22 days for easy pregnancy.

The advantages and disadvantages

Calculate the prediction of ovulation schedule no urine LH test is accurate, but the method is simple, easy to master, do not have to spend money, the commonly used method is still relatively good.

Observation of cervical mucus

Controlled by the hormone secretion of cervical mucus on the basis of the change with the menstrual cycle, so we can through the observation of cervical mucus, to speculate the possible date of ovulation.

Menstruation just ended when estrogen levels are relatively low, the cervical mucus is white or yellow, less sticky, like dry paste, the vagina outside the vagina is slightly moist, dry, underwear will not stick to any mucus, no wet and slippery feeling.

2 days less sticky, like dry paste, this is not easy to conceive.

A, a pregnant rule

During the menstrual cycle, with cervical mucus days again, especially in the cervical mucus is clear, flexible and smooth when.

B, contraceptive rule

The menstrual period, vaginal bleeding period should avoid intercourse; cervical mucus dry period may be the next night again; once the cervical mucus should avoid intercourse, until the re drying three whole day (fourth night) to her.

The advantages and disadvantages

Schedule and calculation method is the same, the cervical mucus observation method is relatively simple and easy to master, and economic application.

TIPS: Observation of cervical mucus problems should be paid attention to

1, observe the cervical mucus from the beginning of the menstrual cycle began, should be carried out several times a day, can be used to wake up, before taking a bath and urinate in front of the opportunity, take the check from the vaginal mucus, not into the vagina.

2, check the cervical mucus could not be in the same room before.

In 3, cervical mucus, never easy pregnancy and easy pregnancy to easy pregnancy is increasing, but not absolute.

Ovulation is relatively safe, and there is no harm to the follicle, ready for pregnant women can be assured.

Generally in the menstrual cycle of eighth days, every day a B-monitoring, if not the developing follicles, can every other day; follicles 10 mm in diameter at a daily check, until the ruptured follicle ovulation date.

The advantages and disadvantages

This method is more accurate.

Basal body temperature measurement

The basal body temperature measurement to determine whether the changes of women’s ovulation is based on periodic basis temperature.

During the menstrual cycle before ovulation, basal body temperature is relatively low, after ovulation, in under the action of progesterone can make the basis of temperature rise 0.3 degrees Celsius than before ovulation, this rise can be directly elevated or within a few days was stepped up in a day.

1, from the sixth day of the menstrual cycle, but if every measurement, short menstrual cycle (25 days), it should be measured from the period of first days.

To put the thermometer thrown to 35 DEG 2, the night before, and disinfection treatment within reach.

3, in the morning of the second day sleep guarantee 6

8 hours, or at least 4 hours after sleeping with oral thermometer; oral temperature measurement; don’t stand up, before the measurement do not eat or drink, not to get up to urinate immediately after the measurement, the measurement temperatures measured on the chart, a curve and numerical before the measured.

4, the basal body temperature was stepped slowly rising women, based on 3 consecutive days of high temperature can rise before 6 days (6 days before the rise in body temperature chart, if one day the body temperature is high, can be deleted, but not by the 2 day temperature) above average temperature of 0.2 DEG C, at this time. Easy to conceive.

5, if you want to contraception of women, and that he is ill, we should indicate in the basal body temperature chart, and to avoid intercourse to burn back 3 days.

The advantages and disadvantages

Needs to be pointed out that the basal body temperature measurement can only suggest that ovulation has occurred, but can not predict ovulation when it happened, because we never know if tomorrow your basal body temperature will rise, thus unable to determine the safe period.

TIPS: contraceptive notes

It is worth noting that, if one day the higher temperature began to rise 6 days before the average temperature is 0.2 degrees, this day is the first day of fever, from this day in first, second, third (second days and third days, the temperature must be maintained at a high level).
