Clearblue pregnancy test

The Clearblue pregnancy test is a modern device that allows you to determine with high accuracy whether you have conceived or not. The test is commercially available, it is simple and convenient to use, however, before using the device, you must carefully read the instructions in order to minimize the risk of a false positive or false negative result.

Clearblue is a subsidiary of the well-known Swiss company Procter and Gamble. Besides the fact that the tests are produced by such a reputable manufacturer with an excellent reputation, their quality is time-tested. Clearblue has been developing and producing pregnancy tests since 2008.

Types of Clearblue Pregnancy Tests

There are several types of tests from Clearblue, the main difference of which is the principle of using the device.

The following types of tests are commercially available:

• Inkjet;
• Electronic;
• Digital.

Accordingly, the more complex the test is, the higher its price category will be. It is noteworthy that the manufacturer of this test system guarantees a reliably positive or negative result, not only after the first day of delayed menstruation. It turns out that Clearblue tests can detect pregnancy a few days before the start of the next period.

How Clearblue Tests Work

The principle of operation of the Clearblue test devices is based on determining the level of hCG (human chorionic gonadotropin) in a woman's urine. Its level is known to rise after conception occurs. The highest concentration of the hormone in urine is observed in the morning, although the device can detect even small doses. The sensitivity of the tests is extremely high and amounts to 10-25 mIU / ml.

After the liquid enters the test, it moves upward through the channels available in the paper indicator and, reaching the set mark, gives either a positive or negative result. Depending on the type of test, it is also possible to determine the gestational age with an accuracy of 1-2 weeks.

Clearblue Plus Pregnancy Test Instructions

This test is the simplest of the entire Clearblue product line, but this does not mean that the accuracy of the results will be skewed. The manufacturer guarantees that pregnancy will be detected in 99% of cases from the expected day of the onset of menstruation.

The device also allows for early testing, that is, you can try to determine pregnancy 5 or less days before the start of the next menstruation. However, in this case, the percentage of reliability of the result will be lower. To minimize the likelihood of error, you need to take the first morning urine sample for testing.

How to do the test correctly? This test system detects pregnancy after urine has been spilled onto the staining tip. The device can be placed directly under the stream of urine or placed in a container of urine. A woman can choose the option that is most convenient for her. It should be borne in mind that the exposure time of urine to the test should be 5 seconds, regardless of the method of its application.

If the biological fluid hits the dough tip in the required volume, it will immediately turn from white to pink. If the tip is not completely colored, it means that not enough liquid got on it. When the tip turns pink, the test should be placed on a flat surface, or it is allowed to hold it with the tip down, but never up. After three minutes, it will be possible to evaluate the result.

How to decode the result? After the specified time has passed, blue lines will appear in the window located on the main device above the tip. They can look like a plus sign or a minus sign, that is, "+" or "-". The plus sign indicates the presence of pregnancy, and the minus sign indicates its absence. In this case, the brightness of the coloring of the lines does not matter. One of them can be lighter, and the other darker, this does not affect the reliability of the result.

It is very important to wait until the lines appear in both windows. If the first display allows you to understand whether there is a pregnancy or not, then the second window indicates the correct operation of the system as a whole. The test is considered correct if there is a vertical blue line in the control window. If not, testing should be repeated using a new test system.

It is important to evaluate the test result no later than 10 minutes after the test. When 10 minutes have elapsed, the test should be thrown away, not paying attention to possible changes on the scoreboard. They are no longer reliable.

Benefits

The Clearblue Plus test has certain advantages over other test systems, for example:

• The test result, which was carried out on the first day of the delay in menstruation, will be 99% positive;
• The study can be carried out five days before the onset of the expected menstruation;
• The test is equipped with a long and comfortable bent handle, so it will be easy to hold and guide it;
• Due to the shape of the device, the testing procedure allows you to observe the rules of hygiene;
• The test does not require an additional container to collect urine;
• The price for the test is about 170 rubles, which is quite inexpensive;
• It is not difficult to evaluate the result.

disadvantages

The disadvantages of the Clearblue Plus testing system include the fact that the result of a pregnancy detection procedure several days before the onset of the expected period may be false negative.

• With this test system, you cannot determine the gestational age in weeks.
• The test cannot be reused.

Clearblue Easy Pregnancy Test Instructions

This test system is represented by an elongated device that has two windows (a window for evaluating the result and a window for checking the correctness of the test). The indicator tip is located under the removable cap. The device is designed to detect pregnancy from the first day of delay in menstruation.

How to do the test correctly? After removing the dough from the individual packaging, remove the cap from the tip. After that, the tip needs to be exposed to urine for five seconds. To do this, you can pre-collect it in a separate container, or simply urinate on the colored indicator. If it completely turned pink, then there was enough urine for the study.

After five seconds, the test is removed from the biological fluid, the tip is closed with a cap and laid out on any flat surface. After two or three minutes, you can evaluate the result.

How to decode the result? Before evaluating the results of the test carried out, you need to wait until a blue stripe appears in the control window, which is smaller in size compared to the main display. This will indicate that the test has completed correctly.

If the woman is pregnant, a plus sign "+" will appear in the main window, which has the shape of a circle. If there is no pregnancy, one horizontal “-” bar will appear in this window.

It is necessary to evaluate the result two to three minutes after the urine test, but no later than 10 minutes after that. If the lines did not appear before this point in time, then the test was carried out incorrectly or the device turned out to be faulty.

Benefits

• The test allows you to determine pregnancy with high accuracy, which is 99%. The only condition is to carry out the procedure not earlier than the first day of the delay in menstruation.
• The test does not require a container to collect urine, as it can simply be placed under the stream.
• For the convenience of the user, the test is equipped with small protrusions, which makes it easier to hold it with your fingers.
• The test is inexpensive, its average price in pharmacies is 130 rubles.
• The test results are easy to evaluate, as they are understood even at an intuitive level. Moreover, each package is equipped with detailed instructions.

disadvantages

• With such a test system, it will not be possible to determine pregnancy earlier than the expected day of the onset of menstruation.
• The device does not allow you to establish the exact duration of pregnancy, but only notifies about its presence or absence.
• The test can only be used once.

Clearblue Digital Pregnancy Test Instructions

The Clearblue Digital tester is a highly accurate device that not only detects pregnancy, but also determines its due date. The device is equipped with an intelligent sensor that calculates the number of weeks and displays the number on the screen.

As for the reliability of the result, it is 99% if the test is performed on the first day of the delay in menstruation. The accuracy of determining the gestational age is also very high and equates to 96%. The device can show a period of 1, 2, 3, 4, 5 weeks. If the pregnancy occurred even earlier, the number 5+ will be displayed on the monitor.

Another feature of the Clearblue Digital Test is that it can be performed up to 5 days before the day of your expected period. However, in this case, the accuracy of the device is reduced to 65%. To increase this indicator, you need to use the first morning urine sample for testing.

How is the test done correctly? In order for the test results to be as reliable as possible, it is necessary to conduct it according to all the rules. To do this, remove the device from the packaging, remove the protective cap from the tip and bring it under the stream of urine. At the same time, the tip should be lowered down.

The jet should affect the test for 5 seconds. After that, it will turn from white to pink. You can also pre-collect the urine in a container for testing and lower the tip of the test into it for 5 seconds.

After the indicator turns pink, the cap is put on again and the device is placed on a horizontal surface. After three minutes, you can evaluate the result.

How to decode the result? It is not difficult to interpret the result, since if there is no pregnancy, the indicator will light up the inscription “not pregnant”. In the event that conception has occurred, the inscription "pregnant" will appear, and below there will be numbers indicating the number of weeks. In this case, the result will remain displayed on the screen for about a day.

Benefits

• The test system is highly accurate, reaching 99%.
• The device can be used to determine the gestational age.
• The device allows even early pregnancy to be detected.
• The test is very easy to use and does not require any special skills to conduct it.
• It is convenient that urine does not need to be collected in a separate container; it is enough to simply bring the device under the stream.

disadvantages

The only drawback of the test can be considered its high cost compared to other devices for determining pregnancy. So, the average price for a Clearblue Digital test is 300-350 rubles.

Some women note such a lack of the test as the disappearance of the result after a day. It turns out that the first test, which notified them of the long-awaited pregnancy, cannot be saved as a keepsake. However, this point does not have any meaning for everyone.

Which Clearblue test should you choose?

Reasons for obtaining an unreliable result

Like any early pregnancy detection system, the Clearblue test can give false results. First of all, it depends on the correctness of the testing procedure. However, even with strict adherence to the instructions, an error may occur.

The following factors can affect the reliability of the result:

• A woman is taking drugs for the treatment of infertility, which contain hCG.
• The woman has an irregular menstrual cycle and performed the test too early.
• If the woman has recently been pregnant (even if the pregnancy has not ended with childbirth), the result may be false positive.
• A woman has an ectopic pregnancy, ovarian cyst, endometriosis, hormone-producing tumor, myomatic nodes.

If a woman still has doubts about the reliability of the results, then she should consult a doctor.
