3, judging the result shows is not pregnant, it is necessary to pay attention to the color changes and the completeness of the test paper.
Early pregnancy test paper results what do you think?
Early pregnancy test paper results mainly by observing the obvious situation of the test zone (T zone) and quality control zone (C zone) to judge, the specific steps are as follows:
quality control zone (C zone) 0 : regardless of whether pregnant, C zone must appear a clear color band, indicating the test paper is valid. test zone (T zone): 0 :C zone is not clear color, or the T zone is clear but C Other situations If the T line continues to fade or disappear, it may indicate biochemical pregnancy, it is recommended to seek medical attention. Weak positive results are recommended to repeat the next day (HCG will deepen with pregnancy), the continuous positive needs hospital confirmation. Please consult the doctor directly if there is any doubt based on the actual cold judgment. 0 1
If there is no visible color in the C zone, the test paper is not valid, it should be re-tested.
If the T line continues to fade or disappear, it may indicate biochemical pregnancy, it is recommended to seek medical attention.
g> Observing early pregnancy paper red leaf mainly judged by the colour condition of the control line and the test line, only the colour of the control line is negative (not pregnant); both are colour positive (indicating the possibility of pregnancy); the colour of the test line is lightly positive (needs further confirmation).
Negative results judge If early pregnancy test paper is only colourful, and the test line is not colourful, indicating that the urine has not detected sufficient concentration of folicular stimulating hormone (HCG), the result is negative, indicating not pregnancy.
As long as the test paper is normal and operating in accordance with the specifications, whether or not pregnancy will be visible. If the control line is not visible, it may be a test paper failure or operation error, it is necessary to re-test.
Positive results judge When the control line and the test line are both colorful (the color of the test line can be deep and shallow), the result is positive, indicating the possibility of pregnancy. The test line is visible because the concentration of HCG in the urine reaches the threshold, and reacts to the chemical on the test paper. If the color of the test line is close to or deeper to the control line, it usually indicates that the concentration of HCG is higher, the likelihood of pregnancy is greater; if the color of the test line is lighter,
For weak positive.
Weak negative analysis Detection line is light (weak positive) may be caused by the following reasons:
Pregnancy time is short : after the fertilized egg is laid, HCG secretion is gradually increased, early hormone levels may lead to the detection line is weak.
0 Detection method is incorrect
1 : if the urine volume is excessive (the concentration of HCG is diluted), the detection time is too early (not as required in the instructions for postmenstrual delay), test paper immersion
Other factors such as ectopic pregnancy (ectopic pregnancy), abnormal embryo development, etc. may cause HCG secretion deficiency, but such situations need to be further diagnosed in combination with clinical examination.
Detection principles and precautions Early pregnancy test paper determines whether HCG is pregnant by testing in the urine. HCG is the hormone secreted by the placenta after pregnancy and excreted by the urine. The chemical substances on the paper (such as anti-HCG antibodies marked by the gold capsule) will bind to HCG in the urine
:
must be carefully read before the detection of the instructions, according to the regulations (such as using morning urination, control the amount of urine, avoid paper pollution, etc.).
must be used within the valid period, as soon as possible after opening, to avoid flooding or exposure to high temperature environment.
weak positive results should be re-tested after 1-2 days, or directly to the hospital for blood HCG testing (more sensitive, more accurate quantitative) or B ultrasound (confirming whether intrauterine pregnancy).

The results confirmed with clinical recommendations Early pregnancy test paper can only be as a preliminary judgment, can not be as a confirmation basis. If the following situation occurs, it is recommended to seek medical attention in a timely manner:
test results are positive or weak positive, need to be tested by blood HCG (quantitative analysis of HCG level) or B supercheck (observing the location and development of the embryo) to clear whether pregnancy and state of pregnancy.
menstruation delayed for more than 7 days, nausea and vomiting, but the test paper results are negative, may detect time too early or hormone levels have not reached the threshold, need to be reviewed or for medical examination.

"two levers" with pregnancy relationship: appearance of "two levers" probability means pregnancy, but early pregnancy test paper is only a preliminary estimate. Because early pregnancy test paper is by detecting the human follicle stimulating hormone (HCG) in the urine to determine whether pregnancy, some special situations such as grapefruit, follicle cancer, etc., HCG levels in the body will also rise, can cause the test paper to appear "two levers"; in addition, the test paper expires, improper methods of use, and so on, can also appear false positive results.
The most accurate method of testing is blood HCG test : blood HCG test is more accurate than early pregnancy test paper. It determines whether you are pregnant by measuring the level of HCG in the blood, and the level of HCG in the blood will rise shortly after the fertilized egg is laid. Generally, it can be detected by blood HCG about 10 days after the same room, and can also help judge the development of the embryo according to the specific values of HCG. B ultrasound :
determine the criteriastrong>: The exact criterion for determining is that B is more than not to see the gestational vesicles. Do B excess, the doctor takes the probe to move on the skin to find the appropriate angle, when adjusted to the right position, can see the image of the uterus. If pregnancy, the uterus will be a little larger than when unpregnant, and can see the gestational vesicles in the uterus, the majority of pregnancy weeks can also see the fetal pulse, which indicates that the pregnancy is normal, the gestational vesicles are located in the uterus.
check time: if there is an abnormal pregnancy, worries of ectopic pregnancy, or unexpected pregnancy, do the B supercheck as soon as possible; young, no basic disease, naturally affected
In the case of pregnant mothers, it is possible to wait until 42 days after pregnancy is stopped, and this can not only determine the location of pregnancy, but also usually see the fetal germ, and determine that the fetus has survived.
B super-examination importance : Early pregnancy is much more than the role of B super pregnancy. It can also judge whether it is ectopic pregnancy, if the fetus is not seen in the uterus, the doctor will go to the "neighbor" of the uterus such as the ovaries, the ovaries and other places to look, if in these places to see the fetus, that is the uterus, the need to terminate the pregnancy. Because ectopic pregnancy will not only let the patient experience a huge psychological decline, but also may trigger
Serious consequences, such as the rupture of the ovarian tract leading to large bleeding, etc. The correct time to detect pregnancy is 18 days after the same period or when the grandmother is not delayed for 7 - 10 days, it is possible to test with early pregnancy paper, at which time it is possible to determine whether you are pregnant. But too early detection may have a false negative result due to insufficient levels of HCG in the body; too late detection although generally can get accurate results, but may miss some timely treatment situations, such as early detection and treatment of ectopic pregnancy.
