Pregnancy test – what the stripes mean
Every woman at least once in her life did a pregnancy test and was looking forward to the cherished seconds to see what kind of verdict we passed the test.
It’s good to see the result clearly and clearly, but sometimes it’s not clear how to interpret it. When preparing the material for writing the article, she herself was surprised that only women do not see on their test.
Let’s try to figure out what can be seen on our tests and how to correctly guess what this means. So, look at the picture and read:
Two strips on the pregnancy test are both clear – it means that you are pregnant.
Two strips, one clear, the second dim – also means a positive result, only the duration of your pregnancy is very small, so the concentration of hormones is still very small. You can make sure that you didn’t see the second strip very simply – in 3-4 days do another test.
One strip on the pregnancy test – the result is negative, alas, you are not pregnant.
If there are no strips on the test – this is not the correct test, its result cannot be considered negative, you need to repeat your research.
I also read about this result, the second strip on the test is a white red outline or a strip appears after 20-30 minutes, all this of course does not mean that you are pregnant. Since the correct result for the test cannot be seen if more than 10 minutes have passed since the test. After the dough has dried, so called "evaporation strips"which are very often mistaken for the desired second strip.
To make the test result as accurate as possible, you should follow these rules:
– the test will not show any result immediately the next day after conception, you need to wait at least a week;
– do not do the test immediately on the first day of the delay of menstruation, wait five days.
A pregnancy test is the easiest and most convenient way to determine pregnancy at home, which is used by most women. However, many of us faced with such an ambiguous result as a pale strip on the test. How to decipher this result and why such an incident happens – consider in today’s article.
About strips on the test
To begin with, we define where the second bar comes from and what it means. The appearance of the second strip indicates that the level of the hormone HCG (human chorionic gonadotropin) has increased, which is a sure sign of pregnancy. The maximum level of this hormone is observed at 8-9 weeks of pregnancy. However, as early as 7-10 days after fertilization, due to the concentration of hCG in the blood, a blood test can determine the presence of pregnancy. In modern tests for pregnancy, the level of hCG is determined in the urine, where this hormone enters much later than in the blood. That is why, a pregnancy test is recommended not earlier than 2 weeks after fertilization or from the first day of menstruation.
When using a pregnancy test, we usually determine the presence or absence of pregnancy by one or two pronounced stripes. If you purchased a quality test and according to the instructions, everything was done correctly, that one strip should appear in any case. Why? The fact is that this strip is a control one, which indicates the suitability of the test and the correctness of the result. But the second strip is a test one and its manifestation signals the onset of pregnancy.

Pale second strip – what does this mean?
If you have acquired a really high-quality test for determining pregnancy, and used it correctly, then, as a rule, the appearance of a second strip, even a pale one, indicates pregnancy. Moreover, in many test instructions there is a warning that even a pale stripe indicates pregnancy. Well, such a “pale” look is due to the fact that the level of hCG in your urine is not yet pronounced, but the presence of this hormone, even in the smallest amount, already speaks about the onset of pregnancy.
Pale strip on a pregnancy test – what to do?
Well, firstly, even if you are completely satisfied with the result, it would not be superfluous to do another control test, preferably if this test comes from another manufacturer. In this case, you can purchase not an ordinary test strip, but an electronic one, so that the result is the most reliable. If both tests have confirmed the presence of pregnancy – we can only congratulate you!
Secondly, sometimes a positive pregnancy test can be an indicator of an ectopic pregnancy, so in any case, after using the test, you should consult a doctor. Especially if you recently feel pain in the lower abdomen, general weakness and other deviations in the state of health. And in any case, if you are pregnant, you should register with a gynecologist as soon as possible.
Another secret pale strips on a pregnancy test
It turns out that the pale strip on the test can tell the sex of the unborn child. As a rule, a low level of hCG and, consequently, a pale strip notifies you that you will soon become the mother of the boy. But high levels of hCG and a bright strip on the test indicates that you will have a girl.
As you can see, the pale strip on the test can tell a lot, so we hope that today’s publication will be useful to you.
We sincerely wish you an easy pregnancy and good health!
Today, the most popular of the test systems are the test strips for pregnancy.
This choice is explained by the simplicity in the device and in use, the affordable price of these tests, which can be bought at any pharmacy and even in the supermarket.
Pregnancy test strips are a narrow plastic plate, with a paper strip glued to it, impregnated with a reagent sensitive to the hCG hormone, a particular human chorionic gonadotropin hormone whose concentration in the blood and then in the urine increases dramatically from the first days after conception and gradually reduced by the end of the first half of pregnancy.
The test procedure using pregnancy test strips is simple: the plate is lowered into the urine tank to the marked level for about 5-15 seconds (indicated in the test instructions), after which the plate must be placed horizontally on a clean, dry surface and the result will be evaluated in 3 5 minutes, but no later than 10 minutes from the start of testing.
Evaluation of test strips
If, after a specified period of time, one color line appears on the test area, the result of a negative pregnancy is most likely not. This line is a control line and its appearance indicates that the test was conducted correctly.
If two colored stripes appear, the test is considered positive, which indicates that the concentration of the hormone hCG is elevated and the pregnancy is most likely to be present.
A weak second line on pregnancy test strips is also considered a positive result.
It should be borne in mind that sometimes test results can be false positive and false negative. Therefore, if the test result is negative, but the woman feels unwell with a long delay of the menstrual cycle, or simply in the case of a positive result, she needs to consult a gynecologist to confirm the pregnancy or to detect possible pathologies in time.
Pregnancy test strips have pros and cons
Pluses of test strips for pregnancy consist in relative simplicity of their use and low price.
Video instruction strip on pregnancy ANSWER
The main disadvantage of test strips is the need to pre-collect urine in a clean, dry container, which makes its use is not very convenient and not hygienic. In addition, if the basis for the reagent is a strip of paper, there is a high probability of an erroneous test result, to avoid which it is necessary to strictly follow the instructions for use, as if you immerse the plate in the urine below a specified level or withstand a time period greater than the specified one, if the urine level is below the specified mark or the test is removed too quickly, the reagent strip will not have time to soak in the urine, in these cases the test will show negative results even in the presence of pregnancy th result. In this case, if the basis for the reagent is not paper, but, for example, latex, the probability of an erroneous result decreases.
Pregnancy Test Strip Sensitivity
The sensitivity of test strips for pregnancy varies from 25 to 10 mIU / ml, the higher the number, the lower the threshold of sensitivity. Thus, pregnancy test strips with a sensitivity of 20-25 mIU / ml are recommended to be used from the first day of menstruation delay, when the concentration of the hormone hCG in the urine is high enough – about 10-14 days after fertilization, the concentration of hCG in the urine is 25-100 mIU / ml. Testing is recommended in the morning when urine has the highest concentration of hormone.
Pregnancy test strips with a sensitivity of 10-15 mIU / ml can be used as early as 3 days before the expected delay of the menstrual cycle and at any time of the day.
?How to read test results
A reliable result of a pregnancy test can be given only after the onset of menstruation delay. But this “after” is very individual. It depends on the quality of the acquired test, and on the course of pregnancy, and on the correctness of use, and even on the shelf life and storage of the test.
Any test has special ZONES, where, in fact, stripes appear.
С (control) – the appearance of this strip during the study shows that everything is in order with the system itself, the test result is TRUE.
T (test) – this strip, reacting to hCG in the urine, appears in the test zone and informs about the presence of pregnancy.
We draw your attention to the fact that the strips on the test should be even, approximately of the same color (although in early pregnancy the test strip may be somewhat lighter than the control one) and be placed across the entire width of the control zone.
It is also necessary to doubt the positive test result if the strip is blurry, barely visible and is located at the junction of the plastic protective substrate and the test base (for the test strip).
Also, it should not be considered a positive white strip for a positive result. The white strip is an unreacted reagent that has become visible due to the large amount of test liquid that has fallen on the test. In other words, if a woman was pregnant, then this reagent would stain and as a result the test would show two full strips. For photos of positive pregnancy tests, see the Tests section.
As a result of testing, you can get 3 results:
Weak strip on pregnancy test
Today, there are quite a number of different methods for determining pregnancy, however, the most popular test is a pregnancy test, which you can conduct yourself at home and find out the result in just a few minutes.
Features of using a pregnancy test
Despite the great popularity of this method for determining pregnancy, it must be remembered that it does not give a 100% guarantee of the correctness of the result.
The fact is that today, many companies produce tests for pregnancy, while not all are high-quality and may have different degrees of sensitivity.
The basis of the work of such tests is the same principle – the test has a certain reagent, which has a direct reaction to the hormone gonadotropin contained in urine. The resulting reaction will indicate whether a pregnancy has occurred or not.
Each test has a special test area and exactly two control strips, which in fact will determine the final result. One of these strips is a control one, and by its appearance it will be possible to judge not only the suitability, but also the informativeness of the test being conducted. At the same time, the second test strip will tell whether urine contains hCG (it is she who has a special coating with a reagent that has a direct effect on the hormone gonadotropin).
Regardless of the manufacturer, each pregnancy test must have instructions, which will indicate exactly how long it may take to get the result. In almost all cases, approximately 5 or 10 minutes later, information will be available. After such a period of time, a second strip may appear, which in this case is capable of having a rather weak color – this will not be considered confirmation of pregnancy.
Not considered a positive result and the case when the test shows the second strip, having a gray or white color (called a drying strip, that is, in this case there was no manifestation of the reagent). Also it is necessary to take into account the fact that such a phenomenon can occur even if too much liquid is spilled on the surface of the dough.
Negative pregnancy test
Quite often such cases occur when, in the presence of pregnancy, the test shows a negative result. It is important to remember that a positive result can only be judged if two clearly pronounced stripes appear on the surface of the dough, while they must have a clear outline, not be blurred. The strips must be the same size, and must be strictly on the control zone, have equal color, intensity and intensity of expression.
Many women who dream of pregnancy, decide to carry out the test very early, while it can show the presence of hCG in the composition of urine, but at the same time, the manifestation of the reagent itself is very weak, which may be due to its minimum content. In this case, it will be necessary to repeat the test, since it is not worth judging the 100% accuracy of the result.
In all instructions attached to the tests, it is written that the weakly pronounced second strip cannot indicate the presence of pregnancy. But at the same time, practice shows that a weakly pronounced second strip may indicate a positive result, which is not always true.
Provided that the second strip has a weakly pronounced color, while it is not only very pale, but also blurry, this may be a sure sign that the test is damaged, defective or expired. Also, obtaining such a result may indicate that the woman herself conducted the test incorrectly.
Quite often there are cases when false positive results occur after an abortion, either due to prolonged use of medications for infertility, as a result of certain disturbances in the functioning of the kidneys, the presence of a tumor in a woman or the formation of a dangerous pathology.
The formation of a poorly pronounced second strip may indicate that the test gave a false result. Therefore, in order to confirm the presence of a pregnancy, it is necessary to carry out another test or consult an experienced doctor.
When re-conducting the test, do not hope to get an accurate result before the first day of the absent menstruation, but there may be exceptions. There is an opinion that the appearance of a weak second strip indicates the presence of an ectopic pregnancy, however, this is not always the case. The fact is that the onset of pregnancy can develop with certain disorders. However, it is worth remembering that a pregnancy test can only tell about the presence or absence of pregnancy, and only an experienced doctor can test its course and development.
How does a pregnancy test work?
The basis of the pregnancy tests is the determination of the presence of hCG in the woman’s urine. But at the same time, not all future moms read the enclosed instructions, which clearly indicate from which day of delay you can get the most accurate result.
In almost all cases, it is possible to get the most reliable result within a few days after the delayed menstruation. And before this period, all tests performed may give a false result, and sometimes only one strip appears on the test.
After the test, it is worth paying special attention to how the second strip that appears appears. It does not matter at all what manufacturer the test was purchased from, as the resulting strip should be even, and of course, be across the entire width of the tester and have a clear outline, even color. The ideal option is considered to be a test, in which both stripes appear equally clearly, have the same hue and brightness.
If the second strip that has appeared is almost invisible or is completely absent, this may indicate that a small amount of hCG is contained in the woman’s body. However, this can happen even if the body produces minimal hCG production (for example, this may indicate a threat of miscarriage or the development of certain pathologies). This phenomenon can occur in the event that the delay of menstruation is already more than a week.
What can cause doubts in the test?
In some cases, a non-pronounced second strip on the dough may indicate that a poor-quality test was purchased (both strips have a non-pronounced color) – for example, the test was stored for too long, storage was performed incorrectly, and the expiration date had passed.
Provided that a blurred second stripe appeared, but at the same time it is not pale, and the control area is covered with uneven spots, a low-quality test was acquired. The appearance of the strip occurs as a result of the reaction taking place, which is formed as a result of the interaction of a special dye and hormone in the urine. Provided that the woman is pregnant, a similar reaction can occur earlier than the prescribed time (the second bar appears earlier). Most often this applies to those cases where a red line appears below the control zone. This is the first sign that a poor quality reagent has been applied to the test.
No less important is the psychological factor. Many women strongly want to see the second strip, while not even paying attention to the fact that she has a weak color. But the poorly pronounced second strip is not capable of giving a 100% result. That is why a woman herself can see a positive result even where it simply does not exist.
For example, very often there are cases when on the test you can see a pronounced strip of dark color. But if you look more closely, it becomes noticeable that it also has a white color, which will simply differ in shade. This becomes possible as a result of unreacted reagent. This will be possible even if too much liquid got on the test itself.
That is why before using a pregnancy test, it is necessary to carefully study the enclosed instructions – the test must be lowered strictly to the specified level, and the test time must be strictly adhered to (in no case can you reduce the test time yourself, as in this case there is no guarantee getting accurate results).
The manifestation of a weak strip on the test
For many women, the manifestation of a weak strip on the test can cause quite a lot of excitement. Very often, in the case of an independent pregnancy test at home, a weak second band appears.
Today, it is the pregnancy test that is one of the most accessible methods for determining pregnancy, while it makes it possible to get a result very quickly.
Today there is a fairly wide range of instant tests, which can be tablet, inkjet, as well as test strips. The most accurate and reliable are precisely jet, as they are very sensitive, but at the same time have a higher cost.
Not only for the test strip, but also for the tablet test, it is the manifesting lines that are important for the reliability of the test. To carry out such a test is very easy and simple, it will be enough to collect the morning urine and for a certain time to drop the test strip into it, and you should strictly follow the instructions.
It is desirable to use morning urine, as it contains the highest concentration of hCG, therefore, it becomes possible to get the most accurate result.
The first strip on the test acts as a control, while its manifestation may indicate that the test is usable, therefore, the results obtained will have a more reliable result. However, to confirm pregnancy, it is worth to be examined by a doctor.
It is the second strip that acts as a tester, which may have a mild color, which can seriously confuse many girls. The manifestation of the second strip becomes possible only if the required amount of hCG is found in the woman’s urine.
A reliable result can only be judged if two uniformly colored stripes appear on the test strips, which should have an equally pronounced hue.
But at the same time, provided that the test will be carried out at an early stage of pregnancy, the second strip may be mild or have a dull shade. This becomes possible in the case that during the first few months of pregnancy, an insufficient amount of hCG can manifest itself in the female body. Therefore, in order to get a more reliable result, you will need to repeat the test or undergo an examination by a doctor.
A false negative result is also quite common, in which a weakly pronounced stripe appears on the pregnancy test. To avoid this, it is necessary to strictly adhere to the instructions for the test, which is recommended not the next day after the delay, but a little later, because at this time in the woman’s body may contain a small amount of hCG, which does not give an accurate result.
To provoke a false-negative result can be the presence of an ectopic pregnancy, as well as in the case of a violation of the proper functioning of the kidneys, which as a result can lead to hormone entering the urine, due to which pregnancy is determined.
If the test shows a weak strip, do not worry, because in this case you should seek help from a doctor. An experienced specialist, after examining a woman, may prescribe a series of tests that make it possible to accurately determine the presence or absence of pregnancy.
