's most sensitive red bars in the world. Except for the "five bars" of the captain during school, the rest are the two bars for to test pregnancy.

Women test whether they are pregnant, the most common way is to use pregnancy test stick to test, one bar means not pregnant; two bars mean pregnant.

For this result, many women are love-hate intertwined. There are two bars for people who don't want to get pregnant, but people who want to get pregnant always deal with one bar, which is really exhausting.

Then in life, there will be another situation in the pregnancy test stick, that is, it shows two bars, but it is " one deep and one shallow ", then this result is pregnant or not pregnant? What does

appear on the pregnancy test stick?

First of all, let me talk about the principle of pregnancy test products on the market:

women will secrete chorionic gonadotropin in their bodies after pregnancy, which is what we often call HCG. HCG exists in human urine and blood, and pregnancy test products contain HCG antigens. Once HCG antibodies in the urine are detected, they will react with them to determine whether they are pregnant.

pregnancy test stick generally has two lines, one is the control line and the other is the test line. How to look at the

pregnancy test stick: After

test, only the control line shows color: it means no conception; after

test, the color of the control line and the test line are clear and obvious: it means you are pregnant;

test has no control line within 5 minutes: explain the pregnancy test stick Invalid; after

test, there are two lines, one dark and one light: if the control line is obvious, but the test line is very light, then it means that there is a possibility of pregnancy, but it is not true that the pregnancy is successful, pregnant and not pregnant The odds are each 50% .

usually has two lines, one deep and one shallow, so you need to retest with a new pregnancy test every two days.

pregnancy test stick appears "one deep and one shallow" reasons:

1) pregnancy test time is too early

some women start to use pregnancy test stick to test whether they are pregnant soon after having sex, especially when menstruation has just been delayed for 1-2 days . At this time, the level of hormones in women is usually not very high. HCG is usually only revealed a few days after the fertilized egg is implanted, and must reach a certain amount before it can be detected.

So if detects early, it is difficult to test it even if you are pregnant, or there are two lines, one deep and one shallow.

2) Operation error

When using pregnancy test sticks to test for early pregnancy, under normal circumstances, morning urine is used to test, and the results are often more accurate.

Because has a relatively high concentration of HCG in the morning, , the result is easier to be accurate, but if it is tested at noon or evening, it will easily affect the test results.

In addition, drinking too much water will also dilute the urine, which will affect the results, and then appear dark and light.

3) Physical differences

Each person's physique is different, and naturally the hormone levels in the body are also different. The level of HCG will also be affected by diseases, drugs and pregnancy history , which may affect the test results.

Some diseases can cause false positives in the test results. If the time between two pregnancies is too short, the HCG value in the body will continue to increase, resulting in the possibility of false pregnancy.

The best time to use pregnancy test sticks

Women's ovulation cycle is around the 14th day of the menstrual cycle. If the same intercourse and successful fertilization at this time, then the fastest fertilized egg to produce HCG will take about one week and .

, because of the large amount of HCG secretion, is after the successful implantation of the fertilized egg, and the implantation of the fertilized egg takes at least 11 days.

So if you want to use the pregnancy test stick to test the accuracy, then wait for about 11 days after have sex with , and then test, it will be relatively accurate. The test result of

is usually displayed in about 1 minute. If there are two clear bars, it means that you are pregnant.

But sometimes because of the low HCG content, you need to wait for 3 minutes. If the two lines appear after 3 minutes, then it also means that you are pregnant. Z2z

is written at the end: Z5z

is not 100% accurate, whether it is a pregnancy test stick or a test strip. Even if the pregnancy test result has two obvious bars, it does not necessarily mean that you are pregnant. Sometimes there will be errors.

Generally speaking, the accuracy rate of pregnancy test sticks produced by regular manufacturers is about 85%-95%, which cannot achieve 100% accuracy.

Therefore, if a woman wants to determine whether she is really pregnant, she needs to go to the hospital for a B-scan. The

B-ultrasound examination can not only find out whether you are pregnant, but also determine whether it is an intrauterine pregnancy, gestational age, etc. It is the best choice to ensure the health of mother and baby.
