The sooner pregnancy is detected, the better for the woman and the baby. At home, this can be determined in the early stages - at 2-3 weeks. For this, the B-Shur-S pregnancy test can be used. Reviews testify to its effectiveness. In addition, it is inexpensive and is in every pharmacy. You will learn about its work and rules of use from the article.

A bit of history

Humanity has always been looking for methods to determine pregnancy. Because of ignorance, many difficulties arose. They began to look for ways a long time ago, but only in the Middle Ages did a scientific approach begin to be used. For a long time, pregnancy was determined by the consistency of urine, its smell and transparency. Pale lemon color, almost transparent with foam on top, testified to conception.

Later they began to wet a piece of cloth with urine and set it on fire. If a woman liked the smell, thenno pregnancy. Progress came only in the middle of the 20th century, when antibodies were isolated in the blood using radioimmunoassay. An analytical method revealed the presence of chorionic gonadotropin - a hormone that is secreted by the placenta of a pregnant woman. They call it HCG.

For 10 years, the method has been studied and improved. After that, a test was created that sets the level of hCG in 2 hours. Such a tool for home use began to be sold in the mid-70s in the United States. The test became widespread in 1985, when Clearblue was released by Swiss entrepreneurs. But he had to deal with it. After 3 years, the company began to sell the usual test strips.

Now this is a common method of determining if conception has occurred. The B-Shur-S pregnancy test is a modern tool for women. According to reviews, it is appreciated for its convenience, compactness and affordable price.

Features

Bee Sure S Pregnancy Test, when in contact with urine, reacts to the hCG hormone. It accumulates in the blood and urine of a woman if fertilization has occurred. The sensitivity of the Bi-Shur-S pregnancy test is 20 mIU / ml. Usually, this concentration of the hormone in the urine appears on the 7th day after conception and increases every day. Therefore, it is advisable to perform an express analysis no earlier than on the first day of a missed period.

According to reviews, the B-Shur-S pregnancy test shows the result with an accuracy of 99%. Inaccuracies rarely occur. What does a positive pregnancy test look like? It shows 2 stripes. In this case, the second may be pale, since the presence of hCG is low. Pricetest - from 20 rubles.

Thanks to this testing method, every woman can determine whether conception has occurred or not. The B-Shur-S test usually shows a reliable result. But if in doubt, even after testing, you can consult a doctor. A specialist with the help of modern equipment will provide accurate information.

Advantages and disadvantages

Bee Sure S Pregnancy Test has the following benefits:

1. Simple and easy to use.
2. Provides fast results.
3. High accuracy.
4. Affordable price.

The main thing is to do the testing correctly. According to reviews, the B-Shur-S pregnancy test shows a reliable result only with a delay in menstruation. He has no other shortcomings. The description of the B-Shur-S test is presented below.

What is it?

B-Shur-S is the most common type of pregnancy test because it is considered cheap. It is impregnated with a reagent that sets the hCG level in the urine.

There is a risk of errors, since you can lower the indicator below the indicated mark or leave it for a long time in the urine. It is important to follow the instructions. Reliability arises from the first day of the delay of menstruation.

Action

What is the principle of the B-Shur-S pregnancy test? It establishes the presence of human chorionic gonadotropin in the urine. He has 2 strips - control and diagnostic. The first works when any moisture hits the surface.

The test strip hasspecial components (antibodies) that react to hCG in the urine. Upon contact of chorionic gonadotropin with labeled antibodies, the second strip turns red. What a positive pregnancy test looks like is shown in the photo.

Acquisition

According to reviews, the B-Shur-S pregnancy test should be bought only in pharmacies. This will prevent the acquisition of a fake. The integrity of the packaging should be checked. The strip should be packed in thick cellophane. It often fills with air.

After the expiration date or if the packaging is damaged, do not perform the test, as the result will still be incorrect. The products of this company are sensitive, so it will be possible to detect pregnancy more reliably with it.

Due date

On what day should I take a B-Shur-S pregnancy test? It is advisable to do this on the 2nd day of a delay in menstruation. For accuracy in early diagnosis, in the evening, on the eve of using the test, you should not eat fatty foods. Sexual contact should also be avoided.

It is preferable to use the strip in the morning after taking the first urine. You need to perform the study before eating. After eating, the answer will not be true. Only at the beginning of the day, the concentration of the hormone is high, so the result is accurate.

Rules of procedure

How to use a pregnancy test? After waking up, you need to go to the toilet. Urine must be collected in a containerand lower the tip of the test strip to the indicated mark in the liquid for a few seconds. Then it is placed horizontally.

These are all the rules on how to properly use a pregnancy test. The result is ready after 5 minutes. After 10 minutes it will be invalid. How to understand pregnancy on a test? Conception is confirmed by 2 strips.

But it is important to consider that a positive result is shown even in the absence of pregnancy. This is usually observed due to a malfunction in the hormonal system. For an accurate result, it is advisable to visit a gynecologist after performing the test, who will examine the uterus. This will determine if there is a pregnancy.

In some cases, in the early stages, if a gynecological examination is not indicative, an ultrasound examination or tests are prescribed. But even if the second strip is weakly visible, it is likely that pregnancy has occurred. You can additionally use a couple of tests from other manufacturers.

Sometimes the hormone is produced not on the 6th day after conception, but on the 14-15th. This period is characterized by the maximum concentration of human chorionic gonadotropin. Therefore, with a negative result and the absence of menstruation, you need to wait a few days and perform the study again. This is the entire manual for Bee Sure S.

Characteristic of conception

Pregnancy is determined by the menstrual cycle. Its characteristics depend on the hormonal system. The first phase is formed by estrogen. This hormone helps the uterus prepare for conception. FROMits control is the endometrium. They cover the uterine body. Due to gradual increase, multiple layers are provided.

Estrogen also leads to the production of follicle-stimulating hormone. It acts on the work of the ovaries. In each of them there are eggs that take part in conception. With the formation of follicle-stimulating hormone, activation of one of the germ cells is observed. It passes into the ovary. This is how the follicle appears.

Follicular neoplasm interacts with luteinizing hormone. Due to its influence, the shell of the neoplasm bursts. The egg is released from the ovary. This phenomenon is called the ovulatory phase.

When a couple ovulates, the chance of conception increases. This process consists in the penetration of spermatozoa into the uterine cavity. They take part in fertilization. From the fusion of germ cells, a zygote is formed. The cystoblast passes into the uterine body. The zygote is attached to the wall of the organ and leads to the appearance of the chorion. This hormone is found only in pregnant women. It is detected with the help of a test and a blood test for hormones. The combined use of both methods allows you to establish conception.

What the results mean

When using the test, the following results appear:

1. No stripes. If everything is done correctly, but there is not a single strip, then the product is defective.
2. One strip. This confirms the absence of pregnancy.
3. Two bright stripes. This result indicates pregnancy.
4. Onebright and the other pale. This result appears with a questionable positive result. Probably pregnancy has occurred, but the concentration of hCG is low. In this case, it is better to repeat the analysis in a few days or do an ultrasound.

Positive result

The presence of two clear lines confirms pregnancy. This happens in the presence of the hCG hormone. Additional signs of pregnancy include the following:

1. My period is delayed by 3 or more days.
2. Mammary glands enlarged.
3. Rectal temperature increased to 37.1-37.3 degrees.
4. Morning sickness.
5. Mood swings.
6. Frequent urination.

It may be that the second stripe is poorly visible, but has blurred contours. The reason is the low concentration of hCG, you need to perform a secondary diagnosis after a few days. But usually this problem appears after the expiration date of the product or if the storage rules are violated.

False positive

This is the case when the test gives two cavities in the absence of pregnancy. Sometimes the dye is developed from the conjugate before the antibody-hCG-dye reaches the reaction zones. This is how blurry spots appear. This result is considered a false positive. But such situations are very rare.

A barely noticeable second band is visible if the test is overexposed, that is, look at the result after 10 minutes or more. This line appears due to the evaporation of water fromtest surface. This destroys the conjugates that release the dye. Since not all women follow the instructions and do not correctly interpret the answer, doctors do not have much confidence in such a diagnosis.

False-positive result occurs from taking special medications, impaired kidney function or due to a large amount of liquid drunk. Often the result is evidence of a trophoblastic tumor. Some gynecological ailments can lead to an increase in human chorionic gonadotropin. To exclude them after a positive result, you should visit a gynecologist.

If hCG was administered to maintain the luteal phase or induce ovulation, then traces of this hormone remain for 10 days after the medication. Therefore, the test shows a false positive result.

False negative test

There are situations where these products provide a false negative response. This is seen more frequently. A false-negative test occurs when the test is performed early or if its sensitivity is low. If there is a risk of miscarriage, human chorionic gonadotropin is not produced very actively, as in a normally developing pregnancy.

The main reasons for a false positive test include:

1. Chemical pregnancy. A fertilized egg is present, but it is not fixed in the endometrium, due to which the embryo quickly dies. The problem appears with fibroids, scars in the uterus, congenital anomalies of the reproductive organ, low progesterone.
2. Ectopic pregnancy. Appears when the embryo did not pass into the uterus, but remainedin the fallopian tubes. It is fixed on the ovaries or the mucous membrane of the abdominal organs. This manifests itself in the form of a sharp pain in the lower abdomen, on the lower back, vaginal discharge of blood, fainting. If these symptoms increase, an ambulance is needed.
3. Miscarriages, abortions, first 2 months postpartum.
4. Urinary tract infections, cysts, ovarian cancer, pituitary disorders.
5. Taking hormonal, narcotic, antihistamine, anticonvulsant medications.
6. Trophoblast tumors.

Another false-negative result appears with long-term use of diuretics, chronic diseases of the heart, kidneys, blood vessels, endocrine disorders, the threat of miscarriage. Alcohol, nicotine, antibacterials, emergency concentration drugs do not affect test results.

For the answer to be reliable, urine must be collected in sterile containers. All manufacturer's instructions must be followed. Before buying, you should check the expiration date. According to reviews, the B-Shur-S test in most cases shows the result reliably.

It is much better to detect pregnancy as early as possible. This will allow you to be more attentive to your he alth, to prevent threatening factors. Just the products of "Bi-Shur-S" will perfectly help with this. The main thing is to follow the instructions from the manufacturer during the procedure.

Thus, in any situation, the test will help not to go to the doctor with a slight delay. First, you can perform a diagnosis at home, and only then forsee a doctor for more details.
